DEF

A belt on a slope, such as the bank of a stream, along which water emerges at atmospheric pressure and flows down the slope.

When pumping occurs from a well in an unconfined aquifer, a seepage face develops between the elevation where water table intercepts the well face and the water level in the well. The existence of a seepage face often leads to well yields which are less than values determined by conventional analysis.
