GIS Site Selection Model for Sanitary Landfill Based on Geotechnical Parameters

Abstract

Solid waste disposal area is a function of many parameters. Geo-technical parameters are very important, since they are often connected to the surrounding open ground. In addition, secure and appropriate land that is usable is also scarce. Geo-technical parameters are also used in this document to establish a GIS model to determine a suitable location for landfill purposes. Surat Metropolitan City is India's most densely populated and fastest growing urban area. The research goals are to perform field experiments to collect data and move the facts to find an optimal position in the GIS platform to evolve a model. The expectations of planners were collected in order to find weights for each parameter using the analytical hierarchical method (AHP). In order to improve decision-making, GIS integration and Multi-Criteria Decision Analysis (MCDA) techniques are applied. It increases an atmosphere for transformation and mixing of geographical data and preferences of planners. Deterministic overlay and buffer operations are carried out by GIS. MCDA approaches test alternatives based on the individual beliefs and preferences of the decision makers. Many alternative sites have been illustrated by study findings. Economic analysis of the chosen site from the point of view of real activities is not included in this report.
