Original Abstract

The existence of the dams retaining water is always connected with the risk of their failure. The failure of a dam gives rise of a flood wave that advances through a valley below the dam. The effects of a dam break wave originated in this way may have disastrous consequences and may cause numerous fatalities and a financial loss exceeding many times the price of the water structure itself. The analysis of embankment dam failures shows that most failures were caused by overtopping and by piping. Overtopping occurs when the water level of the reservoir behind the dam rises above the dam crest. It can be caused by an insufficient spillway capacity, improper manipulation, a landslide in the reservoir or when the design discharge is exceeded. Practical application of evaluation of maximum breach discharge is carried out in a case study (the Korycany dam). The results of the Koryčany dam failure modeling included the maximum breach discharge, the time of the failure duration, the breach discharge hydrograph and the water level in the reservoir.
