Abstract
Solid waste management continues to be one of the major issues facing
municipal planners, which Involves managing activities associated with
generation, collection, transport and disposal of solid waste in an environmentally
compatible manner. Land filling is a common method of waste disposal in
Ethiopia. Recently, due to an increase in the awareness of environmental risks
from land fills, there has been a movement towards the selection of new solid
waste disposal sites for the city, however due to the lack of appropriate criteria
and a set of detailed criteria that consider all aspects of the water resource
protection all the results of the previous researches were inadequate
In order to alleviate this acute environmental problem, a multi criteria analysis
approach using remote sensing and GIS is necessary and immediate.
GIS can be used to convert geo-referenced data into computerized maps and
map analysis tools can be used to manipulate maps in an efficient way. This is
especially useful when dealing with large amounts of data, which is typical in
landfill siting
The result of the study shows that the areas, the city planners proposed for the
landfill site be revised in a way to consider the best sites, some areas of the
central east and southern part of the city, are appropriate as land fill site shown in
the final out put map of the study area.
