地下水流域的自然流域产水量可以通过对流域数学模型的计算机数值解所得到的流动网络进行定量分析来计算。流域天然产水量是流域的一种独特性质，可以作为地下水对流域的补给量的一种度量，也是对流域安全产水量的一种保守估计。地下水的补给和排泄速率在盆地的整个面积范围内因地而异;定量分析可以用来确定集中的位置。地下水流网络的定量解释在流域水量平衡计算中起着重要的作用，因为水流系统一端的地下水补给和入渗与另一端的地下水排泄、蒸散和河流基流之间存在着相互关系。
The natural basin yield of a ground water basin can be calculated from a quantitative analysis of the flow net obtained from a digital computer solution to a numerical mathematical model of the basin. The natural basin yield is an unique property of the basin and can be considered as a measure of the ground water recharge to the basin and a conservative estimate of the safe yield. Rates of ground water recharge and discharge vary from place to place throughout the areal extent of a basin; a quantitative analysis can be used to determine the positions of concentration. Quantitative interpretation of ground water flow nets can play an important role in the calculation of basin-wide water balances due to the inter- relationships between ground water recharge and infiltration at one end of the flow system and ground water discharge, evapotranspiration, and stream baseflow at the other.
