ABSTRACT:
Waste management
system is not regulated in Iraq. At present, there are various techniques used
for solid waste management such as landfill, thermal treatment, biological
treatment, recycling etc. Landfill is the most common mode for the disposal of
solid waste. However, landfill site selection is a quite complex process and it
depends on several criteria and regulations. In this study landfill site
selection is performed for Al-Mahaweelqadaa using Multicriteria Decision
Analysis (MCDA) and Geographic Information System (GIS). It should be mentioned
however, that the existing landfill in this area, is temporary and does not
fulfill the environmental conditions. To select suitable landfill site, several
criteria were considered 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 which are prepared. (MCDA) was used to
evaluate the relative importance of each criterion. Each map layers were formed
with the aid of GIS and final suitability map was created by overlay analyses
of each criterion map. According to obtained results, high and low suitable
areas were determined in the study area. Field and office checks were performed
out to determine the accuracy and suitability of the candidate sites.
