Modeling of dam-break flood wave propagation using HEC-RAS 2D and GIS: case study of Taksebt dam in Algeria

Modeling and Risk Analysis of Dam-Break Flooding in a Semi-Arid Montane Watershed: A Case Study of the Yabous Dam, Northeastern Algeria

Aissam Gaagai et al.

Summary: This study simulated the dam breach failure scenario of Yabous dam in northeast Algeria and analyzed its influence on the downstream urban and natural environments. Sensitivity analysis showed that adjustments in breach width and slope resulted in positive changes in flood wave flow, height, and width, while adjustments in breach formation time had opposite effects. The HEC-RAS hydraulic model effectively simulated the flood wave propagation downstream and highlighted the impact of breach parameters and flood hydrographical pattern.

A comparison of the analytical hierarchy process and the fuzzy logic approach for flood susceptibility mapping in a semi-arid ungauged basin (Biskra basin: Algeria)

Ali Bouamrane et al.

Summary: This study proposes a multi-criteria decision-making tool to identify flood susceptibility areas on a regional scale. By integrating multi-criteria analysis, GIS, and RS techniques, flood susceptibility maps were prepared for the Biskra basin in Algeria. The results showed that high and very high flood susceptibility areas were mainly located in the northern regions and urban areas near drainage networks.
