Investigation of Flood Inundation under Climate Change and Landuse Change for the Small Urban Catchment

Climate change and land use change are two significant factors that impact flood inundation.The effects of these changes can be seen in various regions worldwide, with some areas experiencing an increase in flood frequency and severity while others may see a decrease.Thus, the main objective of this study is to investigate the impact of climate change and land use change on the occurrence of floods.The hydrological data and land use, soil types, and hydraulic data were used as input data to simulate the flood scenarios.Two different land use types, current and future, were used to compare the impact of these changes coupled with the Climate Change Factor (C.C.F.).The result shows that flood depth is not significantly different between current and future land use; the flood depth varies from 0.1 -2.217 meters and 0.3 -2.247 meters for current and future land use, respectively.
