Abstract: Urban flooding oftentimes staggers the livelihood in an urban area mostly in the lowland parts. The research location is in Palembang, Indonesia with approximately 30% of the urban part is in lowland areas. Aur Sub Catchment is one of the 20 sub catchments of Palembang and located in Silaberanti. The main objective of this research is to improve the current drainage system in order to achieve the optimal design for urban drainage arrangement. This research was developed using Duflow (Dutch Flow) 3.8.3 and ArcGIS 10.1 to schematize the drainage system. As a result, there are three development scenarios established; the first scenario is the existing condition, the second scenario is the extreme condition, and the third scenario is the improvement possibilities of the existing drainage system. There are three different types of improvement: dredging, dike, a pump, and a flap gate.  In conclusion, the most feasible, effective, and efficient alternative for overcoming the flooding in Silaberanti is a flap gate combined with the dike construction in the river.  In addition, the implementation of concept “Living with Water” for the further urban expansion is necessary. These technical and practical approaches need to be combined for solving the flooding in Silaberanti.
