Pune has always been known for its good climate, but in the last couple of years the city has been receiving heavy rainfall which has given rise to yearly floods in Pune. The city is also surrounded by dams like the Khadakwasla dam, Panshet dam, Warasgaon dam the overflowing of these dams is the main cause of flooding in Pune. The use of gis can prove to be of immense help in the flood management of Pune.
Dam is a ubiquitously disputed subject ranging from its benefits, the effects of dam construction towards the ecology system, the collapse of local communities and epidemic diseases. The reason for the failure of dams is often internal piping or leakage. Another substantial factor is the overtopping of dams in the rainy season, which gets special importance in this project. In this project we mainly focus on the flooding problems caused by the Khadakwasla dam, which happens to be one of the most important dams in Pune. A small case study of the Khadakwasla dam has been done by studying its reservoir area, areas which are affected due to the overtopping during the monsoons and suggesting methods for reducing the effect of floods in Pune with the help of GIS.
In this paper emphasis has been given on mapping the catchment area, slums in the nearby area which have a direct or indirect effect due to the flooding of this dam, with the help of GIS. GIS offers a great deal to this project, enabling a much more complex analysis than would otherwise be attainable. The characterization of the water balance during a major flooding event is useful to scientists, land use planners and government agencies that need such information to develop strategies for coping with future floods. GIS as a tool in complex social science research is only just beginning to be explored, but the field is expanding rapidly.
