Solutions Analytiques de l’Onde de Rupture de Barrage sur Plan Horizontal et Incliné
Analytical Solutions of the Dam Break Wave Problem on Horizontal and Inclined Inverts
Abstract
Dam break waves have been responsible for numerous losses and tragedies. The present work is focused on simple solutions of the dam break wave problem using the Saint-Venant equations Theoretical solutions are developed for instantaneous dam break of semi-infinite reservoir in initially-dry channels. Both laminar and turbulent flow conditions are considered. Solutions for horizontal inverts are compared successfully with previous experimental results, and they are then extended to sloping channels. The results yield a series of simple analytical solutions that are well-suited for educational purposes as well as for emergency services. Keywords : Dam break wave, Analytical solutions, Saint-Venant equations, Turbulent and laminar flows, horizontal and sloping channels.
