Evaluating the capacity to meet the need of water is crucial in order to fulfil expectations of managers, particularly in the Mediterranean area. The region is risk in terms of resources available as well as a steadily increasing in demand for water. The frontier drain of the city of Souk Ahras is located at the extreme Northeast of Algeria, on the Algerian-Tunisian borders, the study region includes eight city, which are Taoura, Drea, Zaârouria, Merahna, Ouillen, SidiFredj, Heddada and Khedara, these are relatively poor in surface water, but groundwater has always been the main water resource. The region’s population is around 93,000 inhabitants, 45% of them living in rural areas. Annual average precipitation is approximately 470 mm∙y–1, but it is distributed unequally in space and time. The average supply water varies from one zone to another and the coverage of demand by groundwater in the region remains low and does not meet all needs. Faced with the regions socioeconomic growth and development, this situation is expected to worsen in the future.
In this context, the WEAP (Water Evaluation And Planning system) model was applied to simulate the water balance and assess strategies for the sustainable management of water resources and makes it possible to explore different scenarios, in order to choose the desired scenario to ensure the sustainable development of the sub-basin of the border until 2050. The availability of drinking water permanently in rural areas is a factor in the stability of a population and a means of combating the rural migration and the congestion of urban centres.

Zola's novel world can be seen as a play of forces that takes place in a strictly defined spatial configuration between aspirational characters striving to realize their desires; the body in motion becomes their expressive medium. Always semantically marked, movement is not only understood as the hero's movement between points in space. In this analytical perspective, based on the body of La Curée et L`Argent, the movement becomes the embodiment of the will / desire, the transformation of thought into action, what is potential into real.

This paper points out that the ARMA models followed by GARCH squares are volatile and gives explicit and general forms of their dependent and volatile innovations. The volatility function of the ARMA innovations is shown to be the square of the corresponding GARCH volatility function. The prediction of GARCH squares is facilitated by the ARMA structure and predictive intervals are considered. Further, the developments suggest families of volatile ARMA processes.

Problematyka związana z nieszkodliwym przepływem przez morze terytorialne jest od lat przedmiotem zainteresowania doktryny i praktyki. Jednym z takich porozumień jest STRANG l I 00 - Zasady wizyt okrętów państw NA TO w portach NA TO oraz w portach nie należących do NATO. Umowa ta weszła w życie w stosunku do członków sojuszu w 1995 roku. STRANG dzieli wizyty okrętów na oficjalne oraz nieformalne i robocze. Wizyta oficjalna odbywa się na zaproszenie jednej ze stron lub związana jest z ważną państwową albo międzynarodową uroczystością, jeśli druga z zaangażowanych stron zgadza się na przyznanie wizycie tej rangi. Wizyta nieformalna to dobrosąsiedzka wizyta w porcie jednej ze stron, która nie łączy się z żadnymi oficjalnymi uroczystościami. Wizyta robocza realizowana jest w związku z ćwiczeniami NATO, podczas których okręty wymagają napraw, uzupełnienia zapasów oraz transportu ludzi, paliw i innych materiałów. Oprócz wymienionych zasad STRANG reguluje pewne kwestie protokolarne, zagadnienia związane z wejściem w życie i obowiązywaniem jego postanowień, zastrzeżenia do umowy oraz formularz informacji kierowanych do kraju-gospodarza wizyty. Autor omawia również polskie przepisy mające znaczenie w zakresie omawianej problematyki.
