Abstrakt

Water is essential for plant growth and development, and the degree of its availability significantly shapes ecosystems in different climate zones. How does an overabundance or deficiency of water affect the flora in Poland and different parts of the world?

If we throw something into a river, how long will it take to reach a certain location downstream? We talk to Prof. Ian Guymer from the University of Sheffield about our increasingly complex models of this deceptively simple problem.

Abstrakt

Poland is among the countries that are facing water stress, although we largely remain accustomed to having water always there when we need it. Should we take this unrestricted access for granted?

Abstrakt

We can hardly imagine the Earth without majestic trees and omnipresent shrubs. But not all of us realize that these plants owe their success to ubiquitous yet often unnoticeable fungi. What links these two types of organisms together is life-giving water. It is the reason why trees and fungi have been inseparable for hundreds of millions of years. How do droughts affect trees and their evolutionarily ancient symbiosis with fungi?

Abstrakt

Floodplains are highly valuable, but highly endangered ecosystems. Restoration programs need to carefully consider their multifunctionality, ecological value and the provision of ecosystem services. The example of the Danube River illustrates the impacts of various restoration measures.

Abstrakt

Environmental hydraulics is a sub-branch of environmental fluid mechanics that deals with the movement of water and transport processes in both natural water bodies and engineered waterways. Techniques developed to evaluate flow resistance in man-made conduits can be successfully applied to natural waterways.

Abstrakt

Forecasts suggest that the freshwater resources available to our civilization will shrink by 30% in the coming two decades. How can we reverse the degradation of water resources and create a balance between the society’s demand for water and the capacity of the hydrosphere?

Abstrakt

Multi-purpose reservoirs play an important role in satisfying demands for water supply, irrigation, hydropower, drinking water, flood protection, recreation, navigation, and other purposes. At the same time, they can often have considerable negative impacts on the environment and local biodiversity that remain largely unseen. These “dirty secrets” include sediment deposition, cyanobacteria blooms, and greenhouse gas emissions.

Abstrakt

The Vistula’s riverbed is a treasure-trove of relics concealed by continually shifting sands and by the turbid river water. So what lies down there, hidden in the Vistula’s depths?
