Sažetak
The city of Zagreb is situated on the slopes of Medvednica mountain. Creeks that are formed on the southern slopes of Medvednica affect the city's sewage system. Torrential waters from Medvednica caused several floods in the city of Zagreb with significant damage and even human casualties. That was the reason for building flood protection system based on retention basins. Since 1980 on the southern slopes of Medvednica 19 retention basins were constructed that fully protect central and western part of the city from torrential waters. All retention basins are formed with embankment dams. In the case of a sudden collapse of embankment dams, positive downstream wave (shock wave) will be formed. Areas downstream from the retention are densely populated, and in the flooded area there are some hospitals, schools, kindergartens, crafts and police facilities. Shock wave can cause loss of human life and serious material damage in the valley downstream of a dam. In order to analyze possible consequences of such a wave as well as their reduction, there is a need to analyze the hydraulic parameters of shock wave for engineering acceptable scenarios of dam failure. To define hydraulic parameters of such a wave a two dimensional model was developed. The model is based on MIKE 21 package. In this paper the developed model has been described and some results presented.
