    • Landfill siting is a complex process. It is one of the major problems in waste management, where many factors should be taken into consideration when selecting a suitable site for landfill in any given area. At the present time, there are many random waste disposal sites distributed throughout Al-Hashimiyah Qadhaa in Iraq. In this study, the Geographic Information System (GIS) and the Analytical Hierarchy Process (AHP) were used to select the best sites for landfill. The process of selecting sites for landfill in Al-Hashimiyah Qadhaa comprised two steps. First, fifteen different criteria were mapped and incorporated into overlay analyses within GIS software to produce the final suitability index map for the site. The second step comprises the exclusion of unsuitable areas from the final map to simplify identification of the candidate sites for landfill in the study area. The weightings of criteria were identified using AHP, and the weightings of the sub-criteria of each criterion were determined based on multiple factors. In order to accommodate solid waste from 2020 until 2030, two suitable candidate landfill sites were determined which fulfill the required area of 1.013 km2 with areas of 1.374 km2 and 1.288 km2 respectively.

    • Selecting a landfill site is a difficult task because the process depends on many factors and restrictions. Landfill is an optimal solution for the disposal of solid waste in Al-Musayiab Qadhaa, which is located in the northern part of Babylon Governorate. At the moment, there is no landfill site in that area that follows the scientific selection site criteria. For this reason, in this research, fifteen variables were considered (groundwater depth, rivers, soil types; agriculture lands use, land use, elevation, slope, gas pipelines, oil pipelines, power lines, roads, railways, urban centers, villages and archeological sites) using geographic information system (GIS) to find out the best suitable landfill site. In addition, two methods of multi-criteria decision-making were used to derive weights for criterion’s maps on GIS to obtain potential landfill sites. The first method is analytical hierarchy process (AHP) which was used to identify the weight for each criterion from the matrix of pairwise comparisons. The second method was the simple additive weighting (SAW) which is a simple method to solve the problem of the selection landfill sites. After comparison of the results obtained based on combining two final maps resulted from methods of AHP and SAW using GIS environment to determine the pixels percentage of matching and non-matching for two maps, two suitable candidate landfill sites were identified that satisfy the requirements with an area of 7.965–5.952 km2. Area of these sites can accommodate the solid waste generated from the Qadhaa up to 2030.

  • Landfill Sites Selection Using Analytical Hierarchy Process and Ratio Scale Weighting : Case Study of Al-Mahawil, Babylon, Iraq
  • 2017
  • Ingår i: Engineering. - : Scientific Research Publishing. - 1947-3931 .- 1947-394X. ; 9:2, s. 123-141

    • Selecting a landfill site is an optimal solution for the disposal of solid waste inAl-Mahawil Qadhaa, both to fulfill the environmental and scientific requirements,and to comply with regulations and restrictions in this Qadhaa. Presently,there is no landfill site in the area that meets the scientific site selection criteria.Therefore, in this study, two methods of multi-criteria decision-makingand Geographic Information System (GIS) were used to produce a map ofcandidate sites for landfill. Fifteen criteria were entered within GIS: groundwaterdepth, rivers, soil types; agriculture lands use, land use, elevation, slope,gas pipelines, oil pipelines, power lines, roads, railways, urban centers, villagesand archaeological sites. The Analytical Hierarchy Process (AHP) is the firstmethod that was applied to derive criteria weightings using the matrix of pairwisecomparisons. The second method was the Ratio Scale Weighting (RSW),which is based on experts’ opinion, in order to identify the criteria weightingsby giving a ratio score value for each criterion relative to the other criteria.Accuracy assessment (Kappa and Overall Assessment) methods were used tocompare the two raster maps which resulted from the two models, and to determinethe percentage value of matching pixels for the two maps. Two suitablecandidate sites for landfill were identified that satisfy the requirementswith an area of 2.218 km2 - 2.950 km2 in order to accommodate the solidwaste generated from the Qadhaa in the period 2020 to 2030.

  • Landfill Sitting by Two Methods in Al-Qasim, Babylon, Iraq and Comparing Them Using Change Detection Method
  • 2017
  • Ingår i: Engineering. - : Scientific Research Publishing. - 1947-3931 .- 1947-394X. ; 9:8, s. 723-737

    • The selecting of a site for landfill is considered as a difficult process because many criteria should be involved. The main aim of establishing a landfill is to protect the human and environment. Al-Qasim district is considered as the study area in this work. It is one of the main districts in Babylon Governorate, Iraq. There is no systematic site as landfill that fulfil the environmental and scientific criteria in this area. Therefore, the most important fifteen criteria that suited the environmental requirements were selected in the current study. These criteria are: groundwater depth, urban centers, rivers, villages, soil types, elevation, roads agricultural land use, slope, land use, archaeological sites, power lines, gas pipelines, oil pipelines and railways. Two methods of multi criteria decision making AHP (analytical hierarchy process) and SRS (straight rank sum) were applied to obtain the weights of criteria in dissimilar styles. The raster maps of the selected criteria were prepared and analyzed within the GIS software. Then, the change detection method was implemented to compare the two output raster maps resulted from AHP and SRS methods. Two appropriate candidate sites for landfill were selected to accommodate the cumulative solid waste until the year 2030 in Qasim district. The areas of these sites were 2.766 km2 and 2.055 km2 respectively.

    • Babylon Governorate is located in the middle of Iraq and includes five major districts called Qadhaa. It occupies an area of 5315 km2 with population of 2,092,998 in 2015. The process of selecting landfill site is considered complicated task related to many factors and regulations. Currently, there is no landfill site in Babylon Governorate that fulfils the scientific and environmental criteria. Therefore, in this study fifteen of suitable criteria were selected. These criteria are: groundwater depth, urban canters, rivers, villages, soil types, elevation, agriculture, roads lands use slope, land use, archaeological sites, power lines, gas pipelines, oil pipelines and railways. Then these criteria were used in the GIS (geographic information system), which has a high ability to manage and analyse various data. In addition, the AHP (analytical hierarchy process) method was used to derive the weightings of criteria through using a matrix of pair-wise comparison. After that the weighted linear combination (WLC) method was used to obtain the suitability index map for candidate landfill sites. Ten suitable candidate sites for landfill were selected (two for each District), where all these sites satisfied the scientific and environmental criteria which were adopted in this study. The areas of the selected sites were adequate to accommodate solid waste from 2020 until 2030.

  • Soil Characteristics in Selected Landfill Sites in the Babylon Governorate, Iraq
  • 2017
  • Ingår i: Journal of Civil Engineering and Architecture. - : David Publishing Company. - 1934-7359 .- 1934-7367. ; 11:4, s. 348-363
  • Tidskriftsartikel (refereegranskat)abstract
    • The Babylon Governorate is situated in the middle of Iraq. It covers an area of 5,315 km2 and has 2,092,998 inhabitants distributed throughout its five major cities (Qadhaa). Presently, there is no landfill site in the governorate that meets the environmental criteria for the disposal of municipal and industrial waste. Consequently, GIS (geographic information system) and methods of multi-criteria decision making were used here to select the best sites in each city in the Babylon Governorate that would fulfil the environmental requirements. Two sites were chosen in each city. As the groundwater is very shallow in this area, the design should ensure against groundwater pollution by leachate from these sites. To avoid this problem, soil investigation was conducted at these sites so that the most suitable landfill design could be accomplished. The results of soil investigation in these sites include the soil profile, groundwater depth, chemical properties, allowable bearing capacity, Atterberg limits test results and material characteristics of the soil strata. From the research, it is believed that the best design is one that puts the landfill above ground.
