Abstract:

The failure of a major flood control structures, like dams, involves rapid transients with strong interactions between flow and topography which may expose the surroundingpopulation to serious risks. In order to simulate the consequences of a dam failure in a complex topography correctly, present study explores a series of small- scale laboratoryexperiments of dam- break waves propagating over loose granular beds. The case ofplane bed with various concentrations is investigated. Experiments were carried out in anideal flume with a fast up- ward moving gate, and instrumentation of the tests performedby means of fast digital imaging through the sidewalls of flume. Results include water surface level time evolution, maxima wave levels and time to peak
