Detailed Description

IHACRES模型

  

       IHACRES是一个UH降水径流模型,它在集水处被汇集。集水储存的集水地降水指数sk被计算,它依赖于先前的降水量和集水地干旱度而0和1之间变化。0表明集水地是干旱的,目前的降水会产生有效雨量;1表明集水地是饱和的,目前的所以的降水会变成有效径流。

                       

式中,c非线性存储的最大容积;rk是在第k时间段的实际降水;uk是有效降雨量;τwtk)是温度tk时集水地烘干的时间常数。根据:

                       

式中,τw20℃时集水地烘干的时间常数;f是描述温度变化对烘干速率影响的因子。

      有效雨量uk的计算如下:
