ASSESSMENT OF WATER RESOURCES
1. Purpose and objectives
To provide an approach to the assessment of the water resources in a region or state. The results of the assessment will provide the scientific basis for decisions on economic development, agricultural zoning, water conservancy planning, and rational development and utilization of water resources.
This component briefly describes the organization needed for an assessment and the methods to be used.
Water resources assessment in China was mainly carried out at the provincial level (including provinces, municipalities and autonomous regions) according to the unified disposition, requirements and technical standards. Then, on the basis of water resources regionalization, namely, by dividing the whole country into 10 large basins, the basin authorities or concerned departments compiled the assessment results of the provinces at basin level, determining the corresponding results for each basin. Finally, compilation of the assessment results of basins and preparation of the final report on national water resources assessment was organized by the Bureau of Hydrology, Ministry of Water Resources and Electric Power.
The assessment consists of four parts: surface water, groundwater, pollution of water sources, and analysis of balance between water supply and demand. A vast amount of data on hydrological elements, on water use investigation and on dynamic observation of groundwater at more than 2000 hydrological stations and 9000 precipitation stations has been used in the assessment.
The main contents of this component are as follows:
Historical data observed and investigated on hydrometeorological elements.
Tabulations of estimated results and distribution maps of surface water and groundwater resources in provinces, basins and the whole country. Individual parameters and synthetic assessments of water quality, with distribution maps, etc.
5. Operational requirements and restrictions
These technical methods may be used by hydrologists with knowledge of basic theory and practical experience to a certain degree in hydrology and hydrogeology.
6. Form of presentation
Technical documentation in English.
7. Operational experience
These methods have been widely used in water resources assessment in China since 1980, and the methods of computation and the quality of the assessment have been continually improved. A report on assessing national water resources using these methods has been published in Chinese.
8. Originator and technical support
Department of Hydrology, Ministry of Water Resources, P.R.C.
10. Conditions on use
Cost of reproduction and mailing.
