Abstract

Purpose This 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/approach To 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. Findings Geospatial 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/value Overall, 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.

基于HEC-RAS 2D和GIS的溃坝洪水波传播建模——以阿尔及利亚Taksebt大坝为例

目的本研究旨在预测Taksebt大坝溃坝后可能发生的与洪水波传播相关的后果，并提出有效的应急行动计划。设计/方法/方法为了实现本研究的目标，水力模型HEC-RAS 2D用于溃坝波的洪水路径，该模型对Taksebt大坝下游的水力特性进行了估计。Findings在地理信息系统（GIS）环境中对模拟结果进行的地理空间分析表明，如果发生Taksebt溃坝事件，许多居民区被认为处于危险之中。根据获得的结果，提出了一项应急行动计划，以缓和下游风险地区的伤亡。原创性/价值总体而言，本研究表明，2D水力建模和GIS的集成在提供溃坝波传播的真实视图方面提供了强大的能力，从而增强了对相关风险的评估并提出了适当的缓解措施。
