- 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 land¿ll siting with grading values greater than 4.0. This included five sites distributed in three qadhaas of governorate.

Journal article (peer-reviewed)abstract
- In Najaf Governorate, Iraq, there are five landfill sites. This study aims to rank these sites based on their criteria which are site capacity, land elevation and land price. AHP (analytic hierarchy process) method was used to weight the criteria and the technique for order preference by similarity to ideal solution. Fuzzy TOPSIS (technique for order of preference by similarity to ideal solution) method was used to rank these sites from best to worst. Based on AHP method, the site capacity criterion was the most important than land price and land elevation.
