Urban flooding has become a major concern in rapidly urbanizing cities due to increased impervious surfaces, inadequate drainage systems, and high-intensity rainfall events. This study presents rainfall–runoff modelling and urban flood analysis for the Bhavanipuram area of Vijayawada using EPA SWMM 5.2 integrated with GIS techniques. Elevation and rainfall datasets were collected and processed to generate contour maps and Digital Elevation Model (DEM). Intensity–Duration–Frequency (IDF) curves were developed using the Gumbel distribution method to estimate rainfall intensity under different return periods. The study area was divided into sub-catchments and modelled in SWMM by defining conduits, junctions, outfalls, and rain gauges. Dynamic wave routing was used to simulate runoff and drainage behaviour during storm events. Results indicate that low-lying regions and highly urbanized sub-catchments experience higher runoff generation and water accumulation. Certain conduits showed surcharge conditions due to inadequate drainage capacity. The study demonstrates that GIS and SWMM integration provides an effective framework for urban flood modelling, flood-prone area identification, and sustainable storm water management planning.
KEYWORDS
This study presented rainfall–runoff modelling and urban flood assessment for the Bhavanipuram area of Vijayawada using SWMM 5.2 integrated with GIS techniques. The analysis demonstrated that inadequate drainage infrastructure, rapid urbanization, and low-lying terrain significantly contribute to urban flooding. SWMM simulation successfully identified flood-prone nodes, runoff behaviour, and conduit surcharge conditions under varying rainfall events. The integration of GIS and SWMM provided efficient spatial visualization and hydrological assessment of the study area. The study recommends improving drainage infrastructure, implementing sustainable stormwater management practices, and adopting proper urban planning strategies to reduce future flood risks and improve urban resilience.
