摘要：Rawabangun is one of the areas in the City of Toboali in South Bangka Regency that is often flooded. There is a main river that passes through the Rawabangun area, which is the Linei River. The aim of this study is to analyse alternatives that can be used in flood control in Rawabangun. The analysis was carried out with the 5.1 Storm Water Management Model (SWMM) and 5-year planned rainfall. There were 9 overflow points found on the channel, and the implementation of flood control is to be carried out with infiltration wells, retention ponds, and channel modification. The application of infiltration wells with a maximum of 1267 units can eliminate 8 overflow points. The application of 3 units of retention ponds with a maximum of 3 units can eliminate 5 overflow points. Changing the channel depth to 4 m can eliminate all overflow points but is not relevant to be applied.
