Survey of the Effects of Land Use Variation on Flooding Potential in Tang-e-Bostanak Watershed

The use of new methods of Remote Sensing (RS) and Geographical Information System (GIS) in zoning the flooding potential and its variations in a particular geographical area (Tang-e-Bostanak Catchment Area) constitutes the main subjects of this study. In this regard، the production، combination، and composition of effective information layers such as K index and run off in identifying these zones have been noted، highlighting the capacity of GIS. Theaim is the identification and percent of flood zoning and their variations within an 18-year period by RS and land use variation maps. In this study، we have observed excess rainfall under the curve number (CN). According to the results، the above mentioned area isexperiencing a 15% increase in flooding during the 18-year period.
