Abstract

Nowadays, in order to ensure high quality of municipal services, and thus a high quality of life for the local community, the authorities of both the basic local government unit and managers of municipal enterprises must strive to maintain high standards of sustainable development. The level of quality of life and services provided can be determined by various dimensions, such as: ecological environment, housing conditions, ecological production in the field of consumer goods, balance between built-up areas and green areas, care for agricultural areas, limiting the deepening social stratification, rational economy water or rational waste management. Therefore, the paper presents a theoretical analysis of the main directions of sustainable development in the activities of municipal enterprises.

Abstract

The paper presents the concept and deployment of the agro-hydro-meteorological monitoring system (abbrev. AgHMM) created for the purposes of operational planning of regulated drainage and irrigation on the scale of a drainage/irrigation system (INOMEL project). Monitoring system involved regular daily (weekly readings) measurements of agrometeorological and hydrological parameters in water courses at melioration object during vegetation seasons. The measurement results enable an assessment of the meteorological conditions, moisture changes in the 0-60 cm soil profile, fluctuations of groundwater levels at quarters and testing points, also water levels in ditches and at dam structures, and water flow in water courses. These data were supplemended by 7-day meteorological forecast parameter predictions, served as input data for a model of operational planning of drainage and subirrigation at the six melioration systems in Poland. In addition, it was carried out irregular remote sensing observations of plant condition, water consumption by plants and soil moisture levels using imagery taken by unmanned aerial vehicles and Sentinel’s satellites. All the collected data was used for support operational activities aimed at maintaining optimal soil moisture for plant growth and should to provide farmers with high and stable yields. An example of the practical operations using the AgHMM system in 2019 is shown on the basis of the subirrigation object at permanent grasslands located in central Poland called “Czarny Rów B1”.

Abstract

There were done simulations of fuels consumption in the system of electrical energy and heat production based on modernised GTD-350 turbine engine with the use of OGLST programme. In intention the system based on GTD-350 engine could be multifuel system which utilise post-fying vegetable oil, micronised biomass, sludge, RDF and fossil fuels as backup fuels. These fuels have broad spectrum of LHV fuel value from 6 (106 J·kg-1) (e.g. for sludge) to 46 (106 J·kg-1) (for a fuel equivalent with similar LHV as propan) and were simulations scope. Simulation results showed non linear dependence in the form of power function between unitary fuel mass consumption of simulated engine GTD-350 needed to production of 1 kWh electrical energy and LHV fuel value (106 J·kg-1). In this dependence a constant 14.648 found in simulations was multiplied by LHV raised to power –0.875. The R2 determination coefficient between data and determined function was 0.9985. Unitary fuel mass consumption varied from 2.911 (kg·10–3·W–1·h–1) for 6 (106 J·kg-1) LHV to 0.502 (kg·10–3·W–1·h–1) for 46 (106 J·kg-1) LHV. There was assumed 7,000 (h) work time per year and calculated fuels consumption for this time. Results varied from 4,311.19 (103 kg) for a fuel with 6 (106 J·kg-1) LHV to 743.46 (103 kg) for a fuel with 46 (106 J·kg-1) LHV. The system could use fuels mix and could be placed in containers and moved between biomass wastes storages placed in many different places located on rural areas or local communities.

Abstract

Smart farming is about managing a farm using modern information and communication techniques in order to increase the efficiency and quality of plant and animal production and to optimise human labour inputs. It is an inseparable part of a sustainable agricultural economy, where energy-saving and low-emission solutions are of particular importance, e.g. in livestock construction. Animal buildings are one of the main building elements of a farm. The paper presents the use of modern solutions that may result in lower energy consumption, and thus lower operating costs of the building. They also reduce the consumption of natural resources and the emission of pollutants, and ensure animal welfare and safety of the operators’ work. Rational use of energy depends, among others, on from the used insulation materials for the construction of livestock buildings, technical equipment, i.e. lighting, heating, ventilation, as well as zootechnical devices. The profitability of livestock production can also be supported by the use of solar, wind, water and biomass energy. Photovoltaic cells, solar collectors, wind turbines, heat pumps and agricultural biogas plants are used for this purpose.

Abstract

Human activities in relation to aquatic ecosystems result in significant economic losses in the form of contamination of water sources, deteriorating its quality and therefore its availability in lakes, water bodies and even in soil. Hence the need for systematic revitalisation or reclamation of water ecosystems. Such actions, in order to be rational, require a detailed understanding of the causes, and then the use of appropriate technology. The need for the above-mentioned actions result from the weather changes that have been noticeable in recent years, as well as environmental pollutants increasing water eutrophication in reservoirs and stimulating the development of some species of cyanobacteria. These cyanobacteria can cause serious water poisoning, especially in water supply systems. Therefore, a rational, comprehensive technology for the removal of bottom sediments and their processing into organic and mineral fertiliser has been developed with properties similar to manure. It also creates opportunities to improve the structure of soils thanks to the supply of organic carbon, the loss of which was found, among others, in also in soils of Poland and EU. These new possibilities of revitalisation hitherto unknown make it possible to a large extent, compliance with environmental requirements when revitalising water reservoirs and soil.

Abstract

Ethiopia has lost sizable forest resources due to rapid population growth and subsequent increase in the demand for agricultural land and fuel woods. In this study, GIS and remote sensing techniques were used to detect forest cover changes in relation to climate variability in the Kafa zone, southwest Ethiopia. Landsat Thematic Mapper (TM) images of 1986 and 1990, Enhanced Thematic Mapper plus (ETM+) image of 2010 and Landsat-8 Operational Land Imager (OLI-8) image of 2018 were acquired at a resolution of 30 m to investigate spatial-temporal forest cover and land use changes. A supervised image classification was made using a maximum likelihood method in ERDAS imagine V9.2 to identify the various land use and land cover classes. Both spectral (normalised difference vegetation index – NDVI) and post classification change detection methods were used to determine the forest cover changes. To examine the extent and rate of forest cover changes, post classification comparisons were made using ArcGIS V 10.4.1. A net forest cover change of 1168.65 ha (12%) was detected during the study period from 1986 to 2018. The drop in the NDVI from 0.06–0.64 in 1986 to (–0.08)–0.12 in 2018 indicated a marked forest cover change in the study area. The correlation of NDVI values with climate data indicated the forest was not in a stable condition. The declining of the forest cover was most likely caused by climate variability in the study area.

Abstract

This study aims to investigate how grazing is perceived across the Curvature Subcarpathians (Romania) by farmers. We investigate farmers’ attitudes toward and understanding of grazing practice and associated processes involving small ruminants (sheep and goats). Additionally, we review the scientific literature and new discussions about grazing vs overgrazing terms and changes in the Romanian small ruminant livestock. Results of the survey on the total of 101 case studies from villages in 3 counties (Damboviţa, Buzau, and Vrancea) show that: (i) grazing is differently perceived; (ii) most of the areas designated for grazing are located near riverbanks (over 55%); most of the respondents reported that the areas intended for grazing are quite close to the inhabited areas; distances are less than 2.5 km; and over 60% of respondents believe that the areas are continuously subject to soil degradation processes; (iii) answers given in connection with the issues addressed provide both relevance to the Curvature Subcarpathians (6792 km2) and the potential impact of higher pressure of grazing on local areas due to the discouragement of specific transhumance policies (more than 60% required subsidies). The average stocking density is about 4.7 head per ha. In general, beyond different farmers’ perceptions, a scientific question remains open regarding the quantitative impact of grazing on hydrological processes. Hence, a field survey (e.g., rainfall-runoff experiments) to assess grazing pressure on water and soil resources will be performed.

Abstract

The marshes are the most abundant water sources and ecological rich communities. They have a significant impact on the ecological and economic well-being of the communities surrounding them. However, climatic changes directly impact these bodies of water, especially those marshes which depend on rainwater and flooding for their survival. The Al-Sannya marsh is used as the example of marshes in Southern Iraq for this study between 1987–2017. The research takes place throughout the winter season due to the revival of marshes in southern Iraq at this time of year. The years 1987, 1990, 1995, 2000, 2007, 2014, 2017 are the focus of this study. Satellite imagery from the Landsat 5 (TM) and Landsat 8 (OLI) and the meteorological parameters affecting the marsh were acquired from NASA. The calculation of the areas of water bodies after classification using satellite imagery is done using the maximum likelihood method and comparing it with meteorological parameters. These results showed that these marshes are facing extinction due to the general change of climate and the interference of humans in utilising the drylands of the marsh for agricultural purposes. The vegetation area can be seen to have decreased from 51.15 km2 in 2000 to 8.77 km2 in 2017.

Abstract

The present study was to reflect the use of some bacteria in the treatment and removal of pollutants in three selected wastewater sites, including a vegetable oil plant (viz. Al-Etihad Food Industries), the main wastewater treatment station in the city of Hila, and Al-Hila River water from October 2019 to January 2020. The bacterial isolates identified in these three sites were Klebsiella pneumoniae, Escherichia coli, Enterobacteria cloacae, Pseudomonas aeruginosa, Thalasobacillus devorans, Acinetobacter baumannii, and Bacillus subtilis. The molecular study of the bacterial isolates involved the detection of bacterial genera using the polymerase chain reaction (PCR). The results showed that water had a variable nature, depending on the substances in it. It recorded varying chemical and physical property values, ranging between 6.36 and 7.82 for pH and from 2500 to 7100 mg∙dm–3 for total alkalinity. Additional values were 713–2051 μS∙cm–1 for electrical conductivity (EC), 5.90–9.80 mg∙dm–3 for chemical oxygen demand (COD), and 480–960 mg∙dm–3 for total hardness. The given values were also 0.20–0.65 μg∙dm–3, 0.03-0.23 μg∙dm–3, and 0–107 mg∙dm–3 for nitrite (NO2), phosphate (PO4) oils, respectively.

Abstract

The 2150 km2 transboundary Gurara Reservoir Catchment in Nigeria was modelled using the Water Evaluation and Planning tool to assess the hydro-climatic variability resulting from climate change and human-induced activities from 1989 to 2019 and projected to the future till 2050. Specifically, the model simulated the historic dataset and predicted the future runoff. The initial results revealed that monthly calibration/validation of the model yielded acceptable results with Nash–Sutcliff efficiency ( NSE), percent bias ( PBIAS), and coefficient of determination (R2) values of 0.72/0.69, 0.72/0.67 and 4.0%/1.0% respectively. Uncertainty was moderately adequate as the model enveloped about 70% of the observed runoff. Future predicted runoffs were modelled for climate ensembles under three different representative concentration pathways (RCP4.5, RCP6.5 and RCP8.5). The RCP projections for all the climate change scenarios showed increasing runoff trends. The model proved efficient in determining the hydrological response of the catchment to potential impacts from climate change and human-induced activities. The model has the potential to be used for further analysis to aid effective water resources planning and management at catchment scale.

Abstract

The drought ranked first in terms the natural hazard characteristics and impacts followed by tropical cyclones, regional floods, earthquakes, and volcanoes. Drought monitoring is an important aspect of drought risk management and the assessment of drought is usually done through using various drought indices. The western region in Algeria is the most affected by the drought since the middle of the 70s.The current research focuses on the analysis and comparison of four meteorological drought indices (standardized precipitation index – SPI, percent of normal index – PN, decile index – DI, and rainfall anomaly index – RAI) in the Tafna basin for different time scales (annual, seasonal, and monthly) during 1979–2011. The results showed that the SPI and DI have similar frequencies for dry and wet categories. The RAI and PN were able to detect more drought categories. Meanwhile, all indices have strong positive correlations between each other, especially with Spearman correlation tests (0.99; 1.0), the meteorological drought indices almost showed consistent and similar results in the study area. It was determined in 1982 as the driest year and 2008 as the wettest year in the period of the study. The analysis of the trend was based on the test of Mann– Kendall (MK), a positive trend of the indices were detected on a monthly scale, this increasing of indices trend represent the increasing of the wet categories which explains the increasing trend of the rainfall in the last 2000s. These results overview of the understanding of drought trends in the region is crucial for making strategies and assist in decision making for water resources management and reducing vulnerability to drought.

Abstract

In recent years, a growing problem of water deficit has been observed, which is particularly acute for agriculture. To alleviate the effects of drought, hydrogel soil additives – superabsorbent polymers (SAPs) – can be helpful.
The primary objective of this article was to present a comparison of the advantages resulting from the application of synthetic or natural hydrogels in agriculture. The analysis of the subject was carried out based on 129 articles published between 1992 and 2020. In the article, the advantages of the application of hydrogel products in order to improve soil quality, and crop growth.
Both kinds of soil amendments (synthetic and natural) similarly improve the yield of crops. In the case of natural origin polymers, a lower cost of preparation and a shorter time of biodegradation are indicated as the main advantage in comparison to synthetic polymers, and greater security for the environment.

Abstract

Permanent grasslands are the most environment-friendly way of using agricultural lands. Apart from producing fodder, grasslands play many other important non-productive functions. Biodiversity is the key factor decisive for their high natural and productive values. Grasslands play an important role in water retention. Not all types of grasslands may be used agriculturally. Out of 16 types of habitats, 10 may be used for production, the others are biologically valuable. The surface area of permanent grasslands in Poland has markedly decreased during the last decade. Now, they constitute slightly more than 20% of agricultural lands occupying 3127.8 thous. ha (in 2019) including 2764 thous. ha of meadows and 363.8 thous. ha of pastures.

Abstract

Models describe our beliefs about how the world functions. In mathematical modelling, we translate those beliefs into the language of mathematics. Mathematical models can yield prognose on the base of applied fertiliser dose. In this work results of finding yield mathematical model according to fertiliser (nitrogen) dose for perennials (willowleaf sunflower Helianthus salicifolious, cup plant Silphium perfoliatum and Jerusalem artichoke Helianthus tuberosus) on marginal land are presented. Models were described as normalised square equations for dependence between yield and fertiliser doses. Experiments were conducted in lisymeters and vases for willowleaf sunflower and cup plant. For Jerusalem artichoke experiments were done in vases only. All experiments have been doing during two years (2018 and 2019) for different fertilisers doses (45, 90 and 135 kg N∙ha–1) in three repetitions. From simulations maximal yield could be achieved for following fertiliser doses – willowleaf sunflower 104 kg N∙ha–1, cup plant 85 kg N∙ha–1 and Jerusalem artichoke 126 kg N∙ha–1.

Abstract

Unlike many other countries, tropical regions such as Indonesia still lack publications on pedotransfer functions (PTFs), particularly ones dedicated to the predicting of soil bulk density. Soil bulk density affects soil density, porosity, water holding capacity, drainage, and the stock and flux of nutrients in the soil. However, obtaining access to a laboratory is difficult, time-consuming, and costly. Therefore, it is necessary to utilise PTFs to estimate soil bulk density. This study aims to define soil properties related to soil bulk density, develop new PTFs using multiple linear regression (MLR), and evaluate the performance and accuracy of PTFs (new and existing). Seven existing PTFs were applied in this study. For the purposes of evaluation, Pearson’s correlation (r), mean error (ME), root mean square error (RMSE), and modelling efficiency (EF) were used. The study was conducted in five soil types on Bintan Island, Indonesia. Soil depth and organic carbon (SOC) are soil properties potentially relevant for soil bulk density prediction. The ME, RMSE, and EF values were lower for the newly developed PTFs than for existing PTFs. In summary, we concluded that the newly developed PTFs have higher accuracy than existing PTFs derived from literature. The prediction of soil bulk density will be more accurate if PTFs are applied directly in the area that is to be studied.

Abstract

The article is devoted to a topical scientific problem in modern conditions – valuation of land in Ukraine. The imperfection of the existing approaches requires further research on the changing conditions of land use and their impact on land pricing.
A methodology for determining the market value of reclaimed land based on a differentiated assessment of its productivity through crop yields is proposed, taking into account natural and climatic zones and other conditions of a particular region. The basis of the methodology is the application of long-term forecast and a set of forecast and simulation models, in particular the model of area climatic conditions and the model of water regime and water regulation technologies on reclaimed land. At that the crop yield model as a complex multiplicative type model takes into account all main factors influencing crop yield formation: weather, climatic and soil conditions, cultivation techniques, water regime of reclaimed land, etc.
The proposed approaches were tested by the method of large – scale machine experiment using a land plot in the zone of Western Polissya of Ukraine as the example. The obtained results indicate that there is a differentiation in land value, which is a proportional derivative of the yield of cultivated crops depending on the conditions of their cultivation. The variation range of the studied indicators in relative form by the ratio of maximum and minimum values to the weighted average value is for cultivated crops – 393%, and for the above soils – 44.6%. Thus, within one object, the estimated value of land in view of available soils and cultivated crops varies from USD2456∙ha–1 to USD4005 ∙ ha–1, averaging USD3522 ∙ ha–1.

Abstract

According to the SRES A1B climate change scenario, by the end of the 21st century temperature in Poland will increase by 2–4°C, no increase in precipitation totals is predicted. This will rise crop irrigation needs and necessity to develop irrigation systems. Due to increase in temperature and needs of sustainable agriculture development some changes in crop growing structure will occur. An increase interest in high protein crops cultivation has been noted last years and further extension of these acreage is foreseen. Identifying the future water needs of these plants is crucial for planning and implementing sustainable agricultural production. In the study, the impact of projected air temperature changes on soybean water needs, one of the most valuable high-protein crops, in 2021–2050 in the Kuyavia region in Poland was analysed. The calculations based on meteorological data collected in 1981–2010 were considered as the reference period. Potential evapotranspiration was adopted as a measure of crop water requirements. The potential evapotranspiration was estimated using the Penman–Monteith method and crop coefficient. Based on these estimations, it was found that in the forecast years the soybean water needs will increase by 5% in the growing period (from 21 April to 10 September), and by 8% in June–August. The highest monthly soybean water needs increase (by 15%) may occur in August. The predicted climate changes and the increase in the arable crops water requirements, may contribute to an increase in the irrigated area in the Kuyavia region and necessity of rational management of water resources.

Abstract

The presence of natural organic matter (NOM) in water has a significant influence on water treatment processes. Water industries around the world consider coagulation/flocculation to be one of the main water treatment methods. The chief objective of conventional coagulation-based processes is to reduce the turbidity of the water and to remove natural organic matter (NOM) present in solutions. The aim of this paper is to present some developments in terms of improved coagulation for the drinking water of Sidi Yacoub treatment plant located in the Northwest of Algeria.
The experiments involved studying the effects of the application of two coagulants (ferric chloride and aluminium sulphate) on the removal of turbidity and natural organic matter from water by measuring the chemical oxygen demand ( COD) and the UV absorbance at 254 nm. The results showed that the rate of turbidity removal increased from 81.3% to 88% when ferric chloride was applied and from 89.91% to 94% when aluminium sulphate was applied. For NOM removal, the maximum removal rates of COD and UV254 were 48% and 52%, respectively, in the case of ferric chloride. These rates increased to 59% and 65% after optimised coagulation. When aluminium sulphate was used, the rate of removal in water increased from 43% to 55% for COD and from 47% to 59% for UV254 after optimised coagulation. The combination of the two coagulants at equal dosage shows a slight improvement in the values obtained after optimisation, both in terms of turbidity and the NOM.

Abstract

The paper concerns the transformation of water resources induced by the construction and functioning of the Brest Fortress defence structure and presents the current water resources resulting from these changes. The study was conducted by analysing historical materials: maps, plans and written documents. Hydrographic changes were analysed for five study periods covering almost 200 years, from 1823, presenting the hydrographic network before the construction of fortifications, up to 2018, when most of these structures ceased or were repurposed. Hydrographic changes were analysed in detail for the area of the Terespol Fortification. The analysis revealed that almost 80% of the wetland area had disappeared after intensive drainage works, and several dozen originally small and isolated areas had been incorporated into a vast drainage network. One of the consequences of these activities was the creation of significantly transformed artificial catchments within the study area.

Abstract

Multiple anthropogenic agents have turned Lake Maracaibo into a hypereutrophic environment. Heavy metals resulting from the steel and oil industry augment pollution in the lake. There is a lack of research on the ecotoxicological effect of heavy metals in protozoa. To evaluate the ecotoxicological effect of Cr3+, Cr6+, Cd2+, Pb2+ and Ni2+ on free-living ciliated protozoa and to identify suitable ciliated protozoa candidates for bioindicators of water quality; we estimated the lethal concentration for 50% of the protozoa population (LC50) in samples from two stations (S1: narrow of Maracaibo and S2: South of the lake) using ecotoxicological tests in the Sedgewick–Rafter chamber and Probit analysis. The general toxicity patterns obtained for S1 protozoa (Euplotes sp. and Oxytricha sp.) were Cr3+ > Cd2+ > Pb2+ > Cr6+ > Ni2+; and those corresponding to S2 (Coleps sp. and Chilodonella sp.) were Cr6+ > Cr3+ > Cd2+ > Pb2+ > Ni2+. We found statistically significant difference (p < 0.05) in the LC50 of protozoa exposed to Cr3+, Cr6+, Ni2+ and Pb2+ when comparing the two sampling stations. The differences observed in toxicity patterns are probably the result of various kinds of protozoa adaptation, possibly induced by various sources, levels and incidents of exposure to heavy metals contamination of the protozoa studied and to the physicochemical conditions prevailing in the two selected stations. The levels of tolerance observed in the present study, allow us to infer that S2 ciliates are the most susceptible to the contaminants studied and can be used as possible microbiological indicators that provide early warning in studies of contamination by heavy metals in Lake Maracaibo.

Abstract

Municipal solid waste collection points (MSWCPs) are places where residents of municipalities can leave their waste free of charge. MSWCPs should operate in every municipality in Poland. The Geographic Information System (GIS) and analytical hierarchy process (AHP) were used in conjunction as tools to determine potential locations of MSWCPs. Due to possible social conflicts related to the location of MSWCPs, three variants of buffer zones for a residential area were adopted. As a result of the spatial analysis carried out using the GIS software, 247 potential locations were identified in variant no. 1 (which accounted for 7.1% of commune area), 167 for variant no. 2 (6.3% of commune area), and 88 for variant no. 3 (3.8% of commune area). The most favourable locations for MSWCPs were determined using the AHP method with additional criteria for which weights were calculated as follows: the area of a designated plot (0.045), actual designation of a plot in the local spatial development plan (0.397), distance from the centre of the village (0.096) and the commune (0.231), and population density of a village (0.231). The highest weights (over 50%) in the AHP analysis were obtained for 12 locations in variant no. 3, two of which had an area over 3 ha. The adopted methodology enabled to identify quasi-optimal solutions for MSWCP locations in the analysed rural commune. This research has the potential to influence future waste management policies by assisting stakeholders in the MSWCP location.

Abstract

Warna and Pengilon Lakes are very close to each other and connected with the sill, a famous tourist destination in the Dieng Plateau Java. Land-use changes are the main problem that affected the lakes. The conversion of forest into an agricultural area had induced erosion and increased the volume of nutrients discharged to the lake due to high use of fertilisers in potatoes farms. In the dry seasons, water from those lakes was pumped to irrigate agricultural land. This study aimed to determine the water quality of Warna and Pengilon Lakes based on physical, chemical parameters, and phytoplankton communities. Water samples were collected from 4 sites at each lake to analyse biological oxygen demand ( BOD), chemical oxygen demand ( COD), ammonia, nitrate, nitrite, and total nitrogen ( TN). Temperature, pH, dissolved oxygen ( DO), turbidity, and conductivity ( EC) were measured in-situ. During this research, turbidity and BOD in Warna and Pengilon Lakes exceeded the Indonesian water quality standard. Based on the STORET method, the water quality of Lake Warna was assessed as highly polluted for all classes. However, based on the pollution index (PI), Lake Warna was slightly to moderately polluted, as well as the saprobic index was in the β-mesosaprobic phase. Based on the species diversity index of phytoplankton, both Warna and Pengilon Lakes were moderately polluted. The long-term monitoring studies are necessary as an early warning sign of water quality degradation. Therefore, they provide insight into the overall ecological condition of the lake and can be used as a basis for developing suitable lake management.

Long term changes in the quality and water trophy of Lake Ińsko – the effect of the re-oligotrophication?

Abstract

In 1970–2010, during the period of spring circulation and summer stagnation, hydrochemical studies were conducted in Lake Ińsko (Western Pomeranian Lake Region, Poland) with determination of the lake susceptibility to degradation and trophic changes. Also, the effect of the catchment area on the water quality in this waterbody was assessed. The waters of the study lake were characterised by low static index, which is an additional indicator of low dynamics of water masses, and low susceptibility to degradation. In spite of this, significant changes in the lake quality and trophy were observed. The hydrochemical parameters defining water quality of the study lake continued to improve. In the 70’s, the water quality was at the border of class II and III, while in 2006 and 2010 it reached the level characteristic for class I waters. Moreover, in the 70’s and 80’s of the previous century, Lake Ińsko Duże was a mesotrophic lake. Then, an increase in the lake trophy was observed, resulting in signs of eutrophy. At the end of the 90’s and in the first decade of the 21st century, the study lake returned to the state of mesotrophy. No restoration works were undertaken in Lake Ińsko in the study period. The improvement in water quality, called oligotrophication, resulted most probably from the lake reaction to changes in the soil use in the catchment area, since fewer phosphorus and nitrogen compounds flow into the lake, and also from the regulation of the wastewater management in the town of Ińsko.

Abstract

Energy dissipator functions to dissipate the river-flow energy to avoid longitudinal damage to the downstream river morphology. An optimal energy dissipator planning is essential to fulfilling safe specifications regarding flow behavior. This study aims to determine the variation of energy dissipators and evaluate its effect on the hydraulic jump and energy dissipation. For this purpose, a physical model was carried out on the existing weir condition (two steps). It was also carried out on four stepped-weir variations, i.e., three-step, three-step with additional baffle blocks at the end sills, four-step, and six-step. Dimensional analysis was employed to correlate the different parameters that affect the studied phenomenon. The study shows a three-step jump shows a significantly higher Lj/y1 ratio, which is an advantage to hydraulic jumps’ compaction. The comparison of energy dissipation in all weir variations shows that the three-stepped weir has wasted more energy than other types. The energy dissipation increase of the three-step type is 20.41% higher than the existing type’s energy dissipation and much higher than other types. The dimensions of the energy dissipation basin are the ratio of the width and height of the stairs (l/h) of the three-step type (2.50). Therefore, this type is more optimal to reduce the cavitation risk, which damages the river structure and downstream area.
