Water balance analysis method and its application

Hui Ying Peng

Abstract

For reasonable realization and evaluation of regional water resources,the systematic theory method was used to analyze the structure and components of the water system in terms of some specific progresses during water circulation,and the water balance equations of a natural water system and social water system were established,respectively.The calculation results of the components of the water system in the study region were substituted into corresponding water balance equations to check the balance of the equations.If the equations were found to be unbalanced,it indicated the following:(1) The components of the water system are insufficient during water balance analysis,and the tests or statistics for a certain component are lacking.(2) The test or statistical results for some components are not consistent with reality and are not accurate.The proposed method was applied to the water balance analysis for Tianjin City.
