Solid Waste Dumping Site Suitability Analysis Using Quantum GIS for Thiruvallur District, Tamilnadu

Solid waste dumping is a serious problem in developed and developing countries because most solid waste are not dumped in suitable areas Thiruvallur district Tamilnadu. One of the fast developing districts in Tamilnadu has issue in dumping the solid waste generated in the district. The main objective of one study is to identify the potential dumping area for Thiruvallur using GIS tools, using Quantum GIS land suitability analysis is carried out including various data such as landuse, land cover, distance of site from road, lake, river, urban& rural settlement. the data collected are converted into raster format. Weights and ranks are assigned to the raster files based on their contribution to potential site selection. Raster calculation expression formulated to create potential site suitability map. The result map indicates that 8.95 % of total area is highly suitable for solid waste dumping, 47.28 % of total area is moderately suitable for site, 21.45 % of area is least suitable and 22.32 % of total area is not suitable for dumping solid waste. The potential most suitable areas for solid waste dumping falls on the outskirts of the district where the effect of solid waste dumping has least effect on health and environment of the study area.
