Evaluation and analysis of the impact of factors affecting urban flooding using SCS-TR20 and SBUH hydrological models (opens in new tab)

Land use change and intense rainfall, particularly in urban areas, are among the key factors contributing to flood occurrences. This study investigates the impact of land use and rainfall changes on flood events using the Soil Conservation Service - Technical Release 20 (SCS-TR20) and the Santa Barbara Urban Hydrograph method (SBUH) models within the HydroCAD software. A key novelty of this study is the comparative application of the SBUH model-never before used in Iran for rainfall-runoff si...
