Document Type: Journal Paper


The effectiveness of an interceptor drain is reduced if part of the water is allowed to bypass the drain as saturated flow in the material below the drain or as unsaturated flow above the drain. Saturated flow losses below the drain may be reduced to a minimum by placing the drain on an impermeable stratum and by providing a suitable porous envelope. Water bypass above the drain may be more difficult to prevent.
