Abstract

Surface water body ensures environmental sustainability, natural beauty and temperature balance in the urban area. Nowadays the surface water bodies is being filled up to meet the rapid urbanization. The aim of this study is to find out the location and the amount of filled up surface water body area in Khulna City Corporation (KCC) during the last twenty years (1998-2018). Satellite image analysis by geographic Information System (GIS) provides much more accurate result about the land cover change of any area. In this regard supervised image classification method of GIS technology has been applied in this study on Landsat satellite image to identify the location and amount of filled up surface water body area. According to the result, there is a significant land cover changed happen in the last twenty years in Khulna city area and a considerable amount of surface water body area has been replaced by the built-up urban space. Surface water body area not only conserves biodiversity but also retain an excessive amount of water during rainy seasons. Without proper management of surface water body area, Khulna city may face frequent urban flood during rainy seasons, which may increase the sufferings of urban peoples.
