单宽渗流量小于或等于允许设计渗流量（以蓄水水能利用为原则）。

The discharge of seepage per unit width q is lower than or equal to the allowable design discharge (in consideration of storage and exploitation of water energy).

实例计算表明，层面的渗流单宽流量计算值和实测值很相近。

The estimation example shows that on layer surface seepage discharge per unit width is approximates to measured value.
