| dc.description.abstract | Solid waste dumping site is a serious problem in Logia town as most solid wastes are not dumped in suitable sites. The main objective of this study was to select suitable solid waste disposal sites that are economically feasible, environmentally sound, and socially acceptable in Logia town by applying Geographic Information System and Remote Sensing technologies. For this research, data were gathered from different sources. Sources include STRM image from USGS with a spatial resolution of 30×30 m for slope, fault and drainage extractions; Google Earth map of the study area for digitizing road, land-use/land-cover maps generated from Sentinel 2A image with a spatial resolution of 10×10 m. To accomplish the objectives, the present study used factor maps as groundwater well points, slope, fault, built-up area, road network, river, land-use/land-cover, geology and soil map, which were reclassified in GIS environment followed by preparation of the suitability map. Even if the degree of weight to each factor varies, factors were considered important and mandatory in the selection of suitable sites for solid waste disposal. Analytical Hierarchy Process pair-wise comparison module was used to accomplish weights of factor parameters, and finally suitability map was prepared by overlay analyses and assigned as highly suitable, suitable, moderately suitable, less suitable and unsuitable. The final result shows that from total area, 5.93 % (499.43 ha) is highly suitable, 6.4% (537.5 ha) is suitable, 3.23 % (272 ha) is moderately suitable, 1.02% (86.10 ha) is less suitable and 84.99 % (7154.61ha) is unsuitable for solid waste dumping in Logia town. In general, the selection of highly suitable sites requires further geotechnical and hydro-geological analyses to ensure conformity with serious standards required for design and construction of the facility. It was recommended that Logia should consider closing its current dump site for a better location from the possible suitable sites selected in this study especially the site/location on the northern part of Logia town, which is suitable in terms of all buffered parameters as well as other confounding factors that include economy, accessibility and elevation as well as slope. | en_US |
