Tailings dam breach: HEC-RAS dam collapse model

In order to predict the maximum discharge of the rupture (RMD), it is very important to evaluate the statistical data of the influence of the configuration of the dam breach on the most relevant parameters which are needed to be representative enough to get the conclusions. This study summarizes the main points in already finished project which carry out dam breach analysis for the pyrite depostits pond, flotation tailings pond and the accumulation for the collection of leachate, on a Čukaru Peki dams using a one-dimensional hydraulic model called Hydraulic Engineering Center's River Analysis System (HEC-RAS). This study should also serve to extricate the main factors for future conversion of variables in order for better prediction of the dam failures.
