Monitoring the Land Surface and water bodies temperature and its impact on surface water turbidity in Raipur, Chhattisgarh, India

Abstract

Land use land cover change is the process taking place in different parts of the country throughout the world and is adversely affecting the environment and will continue to affect both directly and indirectly. It has an impact on the water resource in a negative way. Rapid urban growth as a major cause of land-use change is one of the biggest reasons for the rise in surface temperature, and LULC change is one of the major causes of concern throughout the world. In developing countries like India, rapid urbanization is greatly influencing surface temperature and water resources. Surface water bodies are greatly affected by the rapid urban growth, which is taking place in almost all parts throughout the country, especially in the central part of India which is having plain areas. Many studies have been conducted by using the thermal data in integration with the Remote Sensing (RS) and Geographic Information System (GIS) techniques for estimation of Land Surface Temperature(LST), and based on those studies, it can be concluded that changing land use has its direct impact on surface temperature as with increasing urbanization rise in LST has been observed. Therefore, the present study has been done to estimate the impacts of changing LULC on surface temperature and turbidity in surface water using the satellite-derived thermal data, and based on results obtained it can be concluded that areas covered with the settlement, open or barren land have a relatively higher temperature than those of the areas which have plants, and vegetation on and nearby it, also waterbodies with turbid areas are showing relatively higher temperature than that of clear surface water.
