  • (Pilica catchment in Sulejów, central Poland). The consequence will be an intensification of freshwater eutrophication, of which the most dangerous symptom, especially in reservoirs which supply drinking water, is the appearance of toxic algal blooms.
  • The development of ecotones positively depends on temperature, rain and water level. From among the many scenarios of global climate change, two : the GISS and GFLD scenarios have been considered in relation to their effect on freshwater ecosystems

  • There have been three different types of utilisation of karst water : drinking water, mechanical power of the springs (and streams), supply for artificial lakes of recreational use. Nowadays, the most important usage is the water supply
  • for the artificial lakes in the Orfü Valley. These lakes were dammed in the 1970s for recreational purposes. To maintain this usage, water pollution has to be prevented in the karst region. - (ZK)

  • China ; Human impact ; Impact ; Phreatic ground water ; Water balance ; Water cycle ; Water pollution ; Water quality ; Water use ; Watershed
  • This paper studies effects of human activities on water cycle in Haihe basin, focusing on the effects on the key elements of water balance and environmental issues caused by unreasonable water development and utilization. River runoff reduction
  • , groundwater over-exploitation, and water pollution have caused a series of environmental problems in the area. The best way to meet increasing water demands of human activities is to raise efficiency of water resources use. Waste water discharge should

  • Uncertainty in water management
  • Hydrological processes and water resources in the face of global climate change
  • Climatic variation ; Decision aid ; Drought ; Forecast ; Global change ; Natural hazards ; Uncertainty ; Water ; Water management ; Water resources
  • Water management is choice in face of bounded uncertainty. This papre presents some theories, as well as 3 principles of uncertainty, namely : of the minimum and maximum of uncertainty and of its immutability. Examples are cited of the undesirable
  • consequences of a failure to heed these principles. Methods of rational decisionmaking in conditions of uncertainty are presented, while methodological considerations are supported by examples of applications in water management.

  • The Northwest Shandong Province constitutes a complex system with very uneven year-to-year precipitation. In order to improve the linkage between design work and water management and to enhance irrigation efficiency within the system, water
  • management reforms and design innovations have been implemented since the introduction of the Production Responsibility System. The manipulation of economic incentives, encouraging farmers to participate in water management and changing the financing
  • situation facing to farmers, are the basic techniques used to improve water management in Northwest of Shandong Province.

  • Study on micro-water-collecting technique in dryland field of spring maize
  • Applied hydrology ; Arid area ; China ; Crop yield ; Evapotranspiration ; Maize ; Shanxi ; Soil moisture ; Technology ; Water use
  • This paper analyses the effect of water storage and soil moisture conservation by means of micro-water-collecting technique in the dryland field of spring maize. This technique not only has the function of regulating and adjusting the amount
  • and distribution of field evapotranspiration, but also can raise the water use efficiency, which results in an obvious effect of increasing crop yield, especially in the dry years.
