Abstract

The industrial, municipal and household solid waste produce lots of environmental issues in urban and rural areas, being one of the major sources of environmental pollution on the Earth's surface. Rapid urbanization coupled with increasing industrial, commercial and economic development, have given rise to an increased generation of various types of waste. This work demarcates the suitable sites for solid waste disposal using Remote Sensing and GIS of an urban environment of Ranchi City. Several factors have been considered in site selection for solid waste disposal. Using different parameters in weighted overlay analysis tool in Arc GIS software a final solid waste dumping site map has been prepared. The parameters such as a road network, railways, drainage, urban, vegetation, soil, geology, slope, and land use/land cover have been analyzed for suitable site selection. The final result indicates, three classes in the study area (Restricted, Suitable and Highly Suitable). The restricted area covers 205 sq km (66.97%), the suitable area covers 52 sq km (19.77%) and highly suitable area covers 40.08 sq km (13.26%) of the total study area. These potential sites are economically and environmentally suitable for solid waste dumping to reduce the environmental problem in Ranchi city.
