Synthèse des lois d'écoulement au droit des seuils et déversoirs : étude théorique et expérimentale.

Abstract

This work aims to study the validation of flow laws used to measure the flow at right thresholds and weirs. For this we conducted the study of flow over 11 spillways placed on some experimental channel with different flow rates. This process aimed at determination of experimental flow coefficients that will be then compared with theoretical values obtained by laws and which can permit to study validation. The comparative study will be done by the method of mean square error. Moreover, this work is the determination of the most efficient weirs by taking as criterion the flow discharge capacity. Finally, some performance conditions during the experimental or actual use of weirs are given.
