DESIGN OF DOWNSTREAM FILTER OF A DAM

Abstract

A study on the proper length of a filter installed downstream and a dam with an end sheet pile is presented in this paper. The finite element method is applied and a numerical model which covers a wide and practical range of variables is designed. The results are provided in non-dimensional graphs which may be used for design purposes. In addition a general design equation is presented to suit cases which cannot be evaluated directly from the graphs. Finally, two numerical examples are given to illustrate the procedure to be followed in designing the length of a downstream filter.
