Abstract In our era, the rapid increase of parallel programming coupled with high‐performance computing (HPC) facilities allows for use two‐dimensional shallow water equation (2D‐SWE) algorithms simulating floods at “hydrological” catchment scale, rather than just “hydraulic” fluvial scale. This approach paves way development new operational systems focused on impact‐based flash‐floods nowcasting, wherein hydrodynamic simulations directly model spatial and temporal variability measured or predicted rainfall impacts even a street Specifically, main goal this research is to make step move toward implementation an effective flash flood nowcasting system in which timely accurate impact warnings are provided by including weather radar products HPC 2D‐SWEs modelling framework able integrate watershed hydrology, flow hydrodynamics, river urban flooding one model.

Floods have a terrible impact on people's lives and property all around the world. In this study, we evaluated modeling capabilities of two Machine Learning (ML) approaches such as Naive Bayes Tree (NBT) (NB) four Multi-Criteria Decision-Making (MCDM) analysis techniques MABAC (multi-attributive border approximation area comparison), TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), VIKOR (Vise Kriterijumska Optimizacijaik Ompromisno Resenje), SAW (Simple Additive Weighting) were applied in Abela-Abaya floodplain Ethiopia. Sixteen flood influencing factors elevation, land use/cover (LULC), soil, aspect, geomorphology, normalized difference vegetation index (NDVI), rainfall, distance from river (DR..), topographic wetness (TWI), sediment transport (STI), stream power (SPI), geology, curvature, flow accumulation (FA), slope direction (FD) used input parameters.

Flooding is a natural disaster with extensive impacts. Desert regions face altered flooding patterns owing to climate change, water scarcity, regulations, and rising demands. This study assessed predicted flash flood hazards by calculating discharge volume, peak flow, depth, velocity using the Hydrologic Engineering Centre-River Analysis System Modelling (HEC-HMS HEC-RAS) software. We employed meteorological morphological data analyses, incorporating soil conservation service (SCS) curve number method for precipitation losses SCS-Hydrograph runoff transformation. The model was applied two drainage basins (An-Nawayah Al-Rashrash) in southeastern Cairo, Egypt, which recently encountered several destructive floods. revealed that 25-, 50-, 100-year storms produced volumes of 2461.8 × 103, 4299.6 5204.5 103 m3 An-Nawayah 6212 8129.4 10,330.6 Al-Rashrash, respectively. Flood risk levels, categorised as high (35.6%), extreme (21.9%), medium (21.12%) were low- very-low-hazard areas. highlighted areas closer Nile River mouth faced greater impacts from torrential rain.
