There will be a possible groundwater divide, if it can get enough groundwater to recharge between two discharging areas in a aquifer system.

同一含水系统中在至少两个排泄区(点)之间有足够的地下水补给源情况下，两个排泄区(点)之间才能形成地下水分水岭。

The principle for water balance analysis is to reversely derive the area of water supply according to runoff amount in the karst system, further to determine the position of the groundwater divide.

水均衡分析法原理是根据岩溶系统径流反推补给面积，进而确定地下水分水岭的位置。
