灌区水量供需平衡模型

(1)        降水的有效水量模型:

1)    农田降水的有效水量B1模型:

     

式中,P1位灌区降落到农田的降水;为形成地表径流;为补给地下水,形成地下径流。

2)    非农田降水的有效水量B2模型:

        

式中,P2为非农田降水;为无效水量。

(2)        侧向地下水补给的有效水量B3模型:

  

式中,G31为灌区侧向补给的地下水;G32位地下径流;Q32为形成地表径流。

(3)        流入灌区地表水的有效水量B3模型:

式中,Q41为地表水或渠道引水;Q42为形成地表径流;G42为形成地下径流。

(4)        井渠结合灌区渠灌需水量模型:

    

式中,Q41位自流灌区渠灌需水量;M1为净灌溉需水量;()为灌溉损失水量。
