  • Assessment and utilization of soil water resources
  • Agriculture ; China ; Groundwater ; Irrigation ; Northern China ; Water ; Water budget ; Water management ; Water resources
  • Based on the analyses of water interactions and water balance, this paper discusses the issues on the assessment and regulation of soil water resources, which lays the scientific basis for limited irrigation and water-saving agriculture.

  • Rough water, smooth water : a comprehensive classification of water-flow characteristics
  • Classification ; Montana ; Runoff ; Taxonomy ; United States of America ; Water
  • Article contains the author's original classification of water-flow characteristics. Classification is made up of 7 categories that may be combined into two broad groups. The A. provides a verbal description (no precise measurements
  • or instrumentation are needed) of the water in each category and a photograph from Montana to illustrate each. He ends by broefly discussing the uses of the classification scheme. - (SLD)

  • Based on the essential principle of sustainable development, this paper puts forward a general idea on water resources optimization and eco-environmental protection in Qaidam Basin, and identifies the competitive multiple targets of water resources
  • optimization. According to the Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environmental protection and sustainable development in Qaidam Basin is finally decided.

  • Ireland's water budget - model validation and a greenhouse experiment
  • Climatic warming ; Drought ; Experimentation ; Greenhouse effect ; Impact ; Ireland ; Model ; Runoff ; Water budget ; Watershed ; Years 1970-79
  • In a previous paper (Mills, 2000) the A. described a simple water budget model that was applied to Ireland for the period 1961-90, but no model validation was attempted. In this paper the A. examines the relationship between the estimated surplus
  • water calculated for the catchment of the Shannon River with the measured discharge for that river. The close correspondence between these values suggests that the model is capable of estimating water budgets components at this scale. A simple climate
  • change experiment is presented that evaluates the impact of greenhouse warming on the water budget of this catchment. Discussion of the results.

  • Environmental and ecological water requirement of river system : a case study of Haihe-Luanhe river system
  • China ; Ecological crisis ; Ecosystem ; Environmental conservation ; Hydrosystem ; Northern China ; Stream ; Water resources ; Water use
  • In order to reduce the environmental and ecological problems induced by water resources development and utilization, this paper proposes a concept of environmental and ecological water requirement. It is defined as the minimum water amount
  • to be consumed by the natural water bodies to conserve its environmental and ecological functions. Based on this definition, the methods on calculating the amount of environmental and ecological water requirement are determined in the case study on Haihe-Luanhe

  • Asynchronism-synchronism of regional precipitation in South-to-North Water Transfer planned areas
  • China ; Hydraulic works ; Precipitation ; Project ; Statistics ; Twentieth Century ; Water management ; Water resources
  • In this research, the AA. try to provide the rational basis for South-to-North Water Transfer Project planning and designing by analyzing the water resources synchronism features for North China versus the middle and lower reaches of the Yangtze
  • River and North China versus the upper reaches of the Hanjiang River. Usually, the water resources of a certain region are estimated according to its natural runoff. The features of the runoff, however, have been distorted greatly due to the impact
  • of human activities. The synchonism features should be obtained by analyzing precipitation rather than by natural runoff series. The AA. regard precipitation as the original water resources for a certain region and use it as the basis for water resources
