| dc.description.abstract | Solid waste management system is the most difficult task that many countries, both developing and developed, are facing. Landfill method is one of the easy and cheap management systems which are always needed for sustainable management of solid waste. The main objective of the study was to select landfill site for the town that is environmentally sound, socially acceptable and economically feasible in Welkite town. To achieve the objectives, the present study was conducted by integrating Geographic Information System and remote sensing for selecting suitable landfill sites. All the factor maps were reclassified and standardized in GIS environment followed by preparation of their suitability map. Analytical Hierarchy Processes pair-wise comparison module was used to derive weights for all factor parameters. Accordingly, 49.64km2(62.17%) of the study area is unsuitable, 22.16km2(27.75%) of the total study area is moderately suitable and 8.04km2(10.1%) is highly suitable for landfill. The finding of the study shows that 9 candidate landfill sites in relation to those evaluating criteria. Landfill site 2 which is located in Addis sub- town, is chosen as the most suitable site. Landfill sites 6 and 9 located in Gubre sub-town are the second and third most suitable sites respectively. Therefore, landfill sites 2, 6 and 9 are ranked from 1 to 3 based on their area and distance from the center and nearby settlements due to their minimum environmental and social negative effects compared to the other sites. In general, landfill site selection has been required appropriate consideration from stakeholders and other concerned bodies.
