Urbanization is the process in which population shifts from rural to cities or urban centers for an improved standard of living due to economic growth and development. As the migration rate increases, urban cities undergo major changes in land use and land cover which trigger several negative effects such as overcrowding, water scarcity, air pollution, loss of productive agricultural lands and forest cover. Remote sensing and Geographical Information System (GIS) are used for monitoring the emerging urbanization of the cities using satellite images. In this study, the land use land cover classification of Surat city has been studied for 26 years (1993-2019). The results showed that the urban built-up area in the city has increased by 175.2% over the years. In this study, the contemporary situation of surface water bodies of Surat city was examined by the intersection of urban land use areas and the digitized surface water bodies. The result reveals the reduction and disappearance of surface water bodies due to the encroachment of urban land-use. This study is done to raise the awareness paid for surface water management issues during the urban expansion process.
