Abstract:

Basin level water analysis is the base for scientific water assessment and rational allocation. Traditional basin level water balance analysis mainly adopted simple lumped models based on limited station data. It is hard to meet complicated basin water resource management when consider spatial changes of water cycle. This paper probed into one water balance analysis way with relationship of upstream and downstream considered based on distributed hydrologic simulation technique and take Haihe River Basin for example. Haihe River Basin is located in North China, which spatio- temporal variability of precipitation and evaporation is relatively great. So we built distributed hydrological model using SWAT, base on hydrological process the water balance of the Haihe River basin and the third - level water resource regions is analyzed. According to analysis results, the article also discussed the necessity and countermeasures for maintaining healthy water balance and reducing basin evaportransprition to carry on real water saving in agriculture.

Key words: distributed hydrological model, Haihe River Basin, SWAT model, water balance analysis
