Contribution a l'etude de l'effet du sol sur le coup de Bélier.

Abstract

Water hammer phenomenon is the largest risk of carrier water pipe , which is caused by the transitional phenomenon that occurs due to flow interruption. This interested researches decades ago to prevent or minimize the risks. water hummer vary according to the case and the dimensions of the pipe where the value increases considerably if those pipes buried, soils are the most important factor affecting its value. Our aim in this study is to explain the phenomenon of runoff Transitional and study the effect of soil factor on water hummer value, and to identify the forces that are applied to the buried pipes.
