Abstract:Urban expansion significantly alters natural hydrological regimes and increases the risk of flooding, particularly in suburban catchments undergoing rapid land-use transformation. The replacement of permeable surfaces with impervious infrastructure reduces infiltration and increases pressure on existing drainage systems. This study evaluates the hydraulic performance of a suburban catchment in southwestern Poland (18.78 km2) using an integrated modelling approach combining SWMM hydrodynamic simulations with high-resolution (1 m) terrain analysis in SCALGO Live Poland. ; Results show that an imperviousness level of approximately 18% is sufficient to exceed the hydraulic capacity of the drainage system during design rainfall events. The introduction of two retention reservoirs (total capacity 180 000 m3) reduced peak flows by 32% and eliminated 93% of high-risk flood zones. The study highlights the importance of integrated hydrological modelling for planning effective stormwater retention strategies in rapidly urbanizing catchments.
