Abstract:
The selection of a suitable landfill site is considered as a complicated task because the whole
process is based on many factors and restrictions. The management of collection and disposal
site of solid waste existing in shambu town is done through open dumping of waste and the
poor quality of the collection process which does not conform to the scientific and
environmental criteria applied in the selection of landfill sites. So this study aims to presents
landfill suitable site selection for solid waste disposal by using geographic information system
and remote sensing with multi-criteria decision analysis. Geographical information system
has a large capacity for managing input data and easy to analysis suitability of landfill site.
Geographical information system combinations with the Analytical hierarchy process and
Multi-Criteria Decision Analysis method were used to derive the relative weighting overlay
for each criterion using pairwise comparison. For this study, 5(five) dominant factors were
adopted (Geology, soil types, land use land cover, slope and roads) to minimize the negative
impacts of landfills in order to find appropriate site for solid waste dumping. Based up on
these factors the results have shown that four sites were suggested as highly suitable for solid
waste disposal. These sites were site1, site2, site3 and site4 which were found in North, North
West, East and South part of 01 and 02 kebele of shambu town. Those sites were easy to
access and manage for disposal of solid wastes
