To minimize the loss of human lives and wealth from the intensive rainfall, the more effective maintenance of the sewer-pipe network and the prevention of the floodings due to the lack of flow capacity of the sewer-pipe need to be made. For that, a system of the GIS-based sewer network analysis for analyzing the flow capacity of the sewer-pipes should be developed to provide proper maintenance of the sewer network for the drainage basin of the metropolitan area and to identify the critical areas to minimize the damages from the intensive rainfalls. This study mainly concentrates on the development of a system for sewer network analysis, thereby forecasting possible areas of the flooding. For the verification of the forecasting results, existing flooding data for the study area have been used. Also, this system contributes to decrease the damages from the flooding by providing alternatives to minimizing the flooding areas such as suggesting proper diameters of the sewer pipes, etc.
