The purpose of this research is to create a database of rainwater drainage systems in urban areas for spatial analysis of rainwater drainage systems using the SWMM 5 model. Solutions to drainage problems in urban areas in Chanthaburi province was performed by using the method of creating a drainage database and analyzed with the SWMM 5 (stormwater management model), which is a hydrological process model that is suitable for urban areas. The drainage capacity was assessed on that existed in the area with 30 years of rainfall by selecting the day with the highest daily rainfall, which was on 23 July 2013 from the weather radar data at the Rayong station of the department meteorology. The results from the study created a drainage system database using conduit, junction, outfall, sub-catchment as a database. The analysis by using SWMM 5 model found that the drainage system in Chanthaburi urban area still had the highest flooding around the road and residential area which was the community area no. 6, Wat Mai Muang Chan, with a depth of 0.82 meters. It was due to the flooded basin, resulting in no area to allow water to penetrate into the ground. Guidelines for preventing flooding are suggested, i.e. adding green spaces, and modifying ground structures such as roads, sidewalks and floors around buildings, to allow water penetrating into the soil.
