Waste management system is not well regulated in Iraq. Despite the fact that there are various
techniques used for solid waste disposal, landfill is the most common mode for the disposal of
solid waste in Iraq, landfill site selection criteria is quite complex process and it depends on several
regulation and factors. In this study landfill site selection is performed by using Multicriteria
Decision Analysis (MCDA) and Geographic Information System (GIS) for the Al-Hashimyahqadaa.
Existing landfills in qadaa are temporary and/or non-conforming to the environmental conditions.
In order to determine landfill site, several criteria were examined such as urban centers, land use,
airports, pipes, power lines, railways, roads, slope, streams, surface water, industrial areas, oil
pipes, liquid gas pipes, soil types are prepared. MCDA was used to measure the relative importance
weighting for each criterion. Each map layer was prepared using GIS and the final suitable
map was created by overlay analyses of each criterion map. According to the results, high and low
suitable areas were determined in the study area. Field site check was performed to determine the
accuracy and suitability of the candidate sites.
