Safety of dams in crisis situations
Abstract The safety of dams in crisis situations can be divided into several areas that can affect their functions. The aim of this work is to focus on water crisis situations on the technical infrastructure during emergencies, of which there were many in the world. The protective function of dams can be based on a thorough analysis and their measures. In the article there was risk analysis performed on a dam of choice. The ALARP analysis was used to determine risks that have to be addressed and taken precautions against. According to F-N diagram it was determined that ALARP region is located at frequencies of 0,000 1 (1-in-10 000 years) and number of people at risk at 1 – 1 000. Next there was a benefit-cost analysis performed of mitigation project, that concluded beneficial value of the dam and the costs of the mitigation project and the BCA ratio came out > 1, thus the mitigation project was recommended. In conclusion there was recommended to use both methods in comparative manner.
