This study aims to predict the consequences of the flood wave caused by the failure of the Taksebt dam and propose an effective emergency action plan for risk mitigation. The hydrodynamic model HEC-RAS 2D was used to simulate the dam-break wave and estimate the downstream hydraulic characteristics. The geospatial analysis in GIS showed that many residential areas are at risk in the event of a dam break, and an emergency action plan was suggested to reduce casualties in the downstream area.
PurposeThis study aims to predict the consequences associated with the propagation of the flood wave that may occur after the failure of the Taksebt dam and suggest an efficient emergency action plan for mitigation purposes. Design/methodology/approachTo achieve the objectives of this study, the hydrodynamic model HEC-RAS 2D was used for the flood routing of the dam-break wave, which gave an estimate of the hydraulic characteristics downstream the Taksebt dam. FindingsGeospatial analysis of the simulation results conducted in a geographic information system (GIS) environment showed that many residential areas are considered to be in danger in case of the Taksebt dam-break event. Based on the obtained results, an emergency actions plan was suggested to moderate the causalities in the downstream area at risk. Originality/valueOverall, this study showed that the integration of 2D hydraulic modeling and GIS provides great capabilities in providing realistic view of the dam-break wave propagation that enhances assessing the associated risks and proposing appropriate mitigation measures.
