Effect of Land Use Land Cover Changes on Urban Floods

The flood disasters are responsible for causing huge losses across the globe whether tangible or intangible. The land use land cover (LULC) is one of the most important factors which influences the hydrological processes; thus, it is very much important to evaluate the effects of LULC on the urban floods. The Vadodara City in India is prone to very frequent urban floods and the most disastrous floods happened in 1994, 1996, 2005, 2014 and 2019 in the recent years. The goal of this study is to find out how LULC changes affect the flood of the Vadodara City. In the present study, image classification using ArcGIS has been carried out for accounting for the LULC changes. The LULC image shows the continuous increase in the urban sprawl throughout the Vadodara City. Rainfall-runoff model has been developed using HEC-HMS. For the evaluation of flood-influencing aspects, the current study analyses hydrological parameters using the LULC and curve number.
