GIS with its capacity for storing and displaying spatial data can be an excellent tool for the management of flooding problems in HCM city. The system can visualize a the overall flooding status of the city, for example i) on a specific rainy day ‘x’ in the past, the locations of flooded areas, their respective depths and durations; ii) how flooding developed at a certain location ‘y’ in the city over the last several years; iii) or the most serious flooding areas of the city, etc. An advantage of the system is its capability to link flooding information with existing related geographic, landmark and drainage systems. This article presents such a system in managing flooding information. The application is developed using the vb.net program and ArcObject library. The system is built to run as independent software on the platform of ESRI ArcGIS Engine 9.2. The application has been piloted effectively for a set of sample data of HCMC. Initial results show this is a promising system to support management of information flooding in Ho Chi Minh City.
