流域水文对全球气候变化的响应模型

 

(1)    流域水量平衡模型:

式中,为降雨量;为流域蒸散量;为月末流域蓄水量;为月初流域蓄水量;为产水量补给地下水的比例;为产水量形成直接径流的部分;为该月地下水动态储量;为上月地下水动态储量;为地下水动态储量中形成地下径流排出流域出口断面的部分;是平均径流来自地下水的比例系数;是表征地下水汇流速度的参数。

(2)    流域蒸发量:

式中,为土壤有效水分;为蒸发不受土壤水分限制的临界值;为最大蒸发量(冠层阻力达到最小值时的蒸发量)。

(3)    流域蒸发力:

式中,为辐射平衡;为地下热通量;为定压比热;为空气密度;为气温下的饱和水汽压;是实际水气压;为饱和水汽压在气温时的斜率;为干湿表常数;为蒸发面至某一参考高度的空气阻力;为冠层表面阻力;是用涡度相关技术直接测定的通量与用梯度扩散理论计算的热通量和水汽通量之比。
