The development of the city of Lublin has been closely associated with the exploitation of water resources in the Bystrzyca river basin. The extension of this city ditinctly affects the water conditions of the middle part of this basin. Lublin
is supplied with water almost solely from underground resources, a situation which has been dictated by excellent-quality and easy-available underground waters and small resources of surface water. A high level of exploitation of the underground waters has led

potential of eastern part of the East-Slovakian Lowland)
The conception of hydrogeographical research of underground waters is outlined and methodical approaches are explained. Problems of natural environment water potential and a balance valuation of ground water resources are given on exemple
The great flood of 1993, Part II: water, water everywhere

Parts of nine Midwestern states were ravaged by the enormous flood on the Mississippi and tributaries in 1993. It became one of the costliest natural disasters ever to strike the USA. Flood chronology, flood damage and human toll are described

In many parts of India, neither the quantity nor the quality of drinking water supplied to the public comply with required standards. In addition there are vast disparities between different regions and communities. The article deals with a chronic
A partial explanation of the dependency of hydraulic conductivity on positive pore water pressure in peat soils
Hydrology ; Natural gas ; Peat ; Porosity ; Soil ; Soil properties ; Soil water
Part of the relationship between positive pore water pressures and hydraulic conductivity in peat soils may be explained by accumulations of methane bubbles. The AA. show how compression and expansion of gas bubbles with changes in pore water
pressure could cause changes in hydraulic conductivity and thus help to explain some observations of dependency of hydraulic conductivity in peats on pore water pressure. Consideration is also given to the effect on hydraulic conductivities of methane gas
going into solution with increase in pore water pressure.

In the course of 90s, the Czech part of Elbe River Basin underwent a significal change in the quality of surface water. The scope and speed of such water quality changes is unprecedented in the Czech as well as in the Central European perspective
. Decrease in the pollution is however limited to the Elbe-River and its main tributaries. It is the area of small water-courses that has to be now in the centre of attention. - (MS)

Irrigation plays a major role in improving agricultural production to cater to the needs of increasing world population. It is to be noted that in countries with advanced technologies, the water use per hectare is about half that of the less
advanced. Thus, new irrigation technology and modern methods of irrigation will play an important part in the achievement of improved irrigation efficiency.
the frozen part may contribute to increase the frost shattering (measurements on matric potential and water content during freezing). Freezing expansion of porous rocks was measured.
Presents a quantitative expression of the frost shattering rate including temperature moisture and lithology. The water migration caused by unfrozen-adsorbed pore-water may play a large role in the frost shattering. The water migration toward

Territorial aspects of water quality in the Lužnice River Basin (South Bohemia) with special emphasis put on the running water. The impact of different human activities on the water quality has been studied. The main role of phosphorus as a driving
force of eutrophication was emphasized. The results are especially important for the regime in the protected area Třebonsko as a part of the international systeme of Biosphere-Reserve. - (MS)

The main objective of the construction of the dam is the safe water supply for Maputo. As part of this project the water quality of the reservoir has been examined partly by a synoptic water quality study in March 1991, partly by studying data from
Neoliberalism and water reforms in western India : commercialization, self-sufficiency, and regulatory bodies
India ; Maharashtra ; Marketing ; Neo liberalism ; Reform ; Regulation ; Urban supply ; Water
The paper deals with the changes brought about by the reforms in water currently under way in many parts of the world. Three particular reforms in the state of Maharashtra are discussed : the commercialization of a parastatal body, the concept
of self-sufficiency as it plays out in the contxt or urban local bodies, and the working of the regulatory body in water. Changes in institutional practices are resulting in changes in subjectivities, foreclosing alternatives, and leading to attempts

Finding solutions to the many water resource utilisation problems that face South Africa has been the driving force behind a large part of the hydrological research that has been undertaken in the country. The changing face of South Africa
and the requirements of managing water in a transformed, democratic society have made the need for cooperation across various discipline even more essential. - (AJC)

Lake-Müggelsee - The use of lake water and its consequences in The eastern part of Germany.
The use of the lake and its catchment area has continuously increased during the past decades and has caused a substantial deterioration of the lake water quality. The lake water shows signs of a permanently growing eutrophisation. Phosphorus
