A dam is a structure that can represent a risk to the surrounding area. In case of a collapse we can face catastrophic consequences of a flood wave, that does not cause only damage to structures but may threaten human lives. In my thesis, I focused on the analysis of the effects of a collapse of a bulkhead, the primary purpose of which is to provide flood protection. I introduced the purpose and the principle of the operating system of the Drtijščica. The Drtijščica Dam is located along the Styrian highway in the municipality of Lukovica, and in case of a collapse it can endanger the inhabitants of the villages downstream, all the way to Domžale. The basis for etermining the number of endangered structures is the calculation of the flood wave in case of the Drtijščica Dam collapse. The thesis is complemented with the theoretical background of the dams and the related risk, which can be reduced with minimal mesures.
