Seepage Analysis and Control for Dams (EM 1110-2-1901)
From ASDSO Dam Safety Toolbox
United States Army Corps of Engineers, 1993
All earth and rock-fill dams are subject to seepage through the embankment, foundation, and abutments. Concrete gravity and arch dams are subject to seepage through the foundation and abutments. Seepage control is necessary to prevent excessive uplift pressures, sloughing of the downstream slope, piping through the embankment and foundation, and erosion of material by loss into open joints in the foundation and abutments. The purpose of the project, i.e., long-term storage, flood control, etc., may impose limitations on the allowable quantity of seepage. The objective of this manual is to provide a guide for seepage analysis and control for dams.
