Earth fill dams are a common type of dam used to store water for a variety of purposes, including irrigation, flood control, and hydroelectric power generation. Seepage is the flow of water through the dam and its foundation. Seepage can be a significant problem for earth fill dams, as it can lead to instability and failure. It occurs in most dams regardless of the measures taken to prevent it by use of impervious cores. Therefore the objectives of seepage analysis should be to determine locations of seepage zones, and the gradients flow rates and uplift pressures, so that adequate control measures can be designed

This book provides an overview of the principles of seepage analysis, methods for seepage analysis, and the application of seepage analysis to the design and construction of earth fill dams. The book is written for professional engineers who are responsible for the design and construction of earth fill dams.

Principles of Seepage Analysis

The principles of seepage analysis are based on the laws of conservation of mass and energy. The conservation of mass requires that the total amount of water entering a system must equal the total amount of water leaving the system. The conservation of energy requires that the total amount of energy entering a system must equal the total amount of energy leaving the system.

These two laws can be used to develop equations that describe the flow of water through a porous medium, such as an earth fill dam. These equations are known as the governing equations of seepage analysis.

Methods for Seepage Analysis

There are a variety of methods that can be used to perform seepage analysis. These methods can be divided into two main categories: analytical methods and numerical methods.

Analytical methods are based on the assumption that the governing equations of seepage analysis can be solved exactly. These methods are relatively simple to use, but they can only be used to solve problems with simple geometry.

Numerical methods are based on the approximation of the governing equations of seepage analysis. These methods can be used to solve problems with complex geometry, but they are more difficult to use than analytical methods.
