小流域雨水资源化理论潜力计算方法与评价模型

 

(1)小流域雨水资源化理论潜力计算方法:

                

式中,Rt为小流域雨水资源的理论潜力(m3);P为流域降水量(mm);A为小流域的面积(km2.

(2)小流域雨水资源可实现潜力表达式:

                

式中,Ra为雨水资源可实现潜力(m3);P为降水量(mm);A为面积(km2),是指可以调控的雨水资源量。

(3)雨水就地利用方式下的可实现潜力计算公式;

               

(4) 雨水叠加利用方式的可实现潜力计算公式:

             

式中,A1区的降水调控系数;A2区的降雨调控系数,可以通过野外降雨径流资料或室内模拟降雨试验确定。

(5)雨水异地利用方式的可实现潜力计算公式;

                  

  (6)小流域雨水资源利用平均模型;

   1)用DWmax表示小流域雨水资源最大可以开发的程度:DWmax可以表达如下:

              

式中,Ra为可实现潜力;Rt为理论潜力。

2)WDreal表示小流域雨水资源实际开发的程度:WDreal可表达如下:

           

式中,Rr为现实潜力;Rt为理论潜力。

3)Wd表示小流域的实际需水程度,则Wd可以表达如下:

           

式中,Rd为实际需水量;Rt为理论潜力。
