ABSTRACT
Solid
waste management aspect is one of the most important challenges facing the
local administration in the Governorate of Najaf. Therefore, this study aims to
provide for solid waste management problem by choosing the best locations for
the establishment of sanitary landfills in the governorate. In this study, GIS
(geographic information system) and MCDA (multi-criteria decision analysis)
were used based on 17 environmental, economic and geological criteria converted
to input digital map layers. These were urban centres, cemetery, airports,
electrical power lines, oil pipes, railways, roads, slope, historical sites,
main rivers, industrial areas, religion sites, wells, military area, electrical
power plants, nature reserves and national borders to select most importance
sites in the governorate. AHP (analytic hierarchy process) method was used in
weighting the criteria used. All layers’ maps were graded from 0 (not suitable)
to 5 (most suitable) using spatial information scale then SAW (simple additive
weighting) method was integrated in GIS used to calculate the suitability index
for the studied area. The results indicated that 4.4% of the study region is
suitable for landfill siting with grading values greater than 4.0. This included
five sites distributed in three qadhaas of governorate.
