GIS and AHP based modeling for landfill site selection (case study: west side of Mosul city)

Abstract

<jats:p>The accumulation of large quantities of solid waste inside Mosul city becomes a real residential and municipal management problem. There are many reasons including the existence of unplanned dumping sites within the city boundaries, and the absence of scientific researches which applies modern techniques for selecting the optimal solid waste landfill. This study uses geographic information system (GIS) and analytic hierarchical process (AHP) which is used to extract the weights with the help of Super Decision SD software. The studied variables data can be classified according to specified processing method into two types: continuous data, and discrete data. The ranking map has been designed after multiplying each variable with its extracted weight, then the final map has been created based on the values obtained from the ranking map. The results show that the optimal landfill area is located at south west Mosul city. This study aims at building a model by using GIS to determine the optimal and potential solid waste landfill site.</jats:p>

Multi-Criteria Analysis for Selecting Suitable Sites of Water Harvesting in Northern Al Tharthar Watershed

“…The Table 3 demonstrates 14*14 of pairwise comparisons. First, set a hierarchy system of variables (Faisal & Ahmed, 2018). Second, is to derive weights from a pairwise comparison of the importance between each two relevant parameters.…”

“…Finally, the consistency ratio is calculated according to pair-wise comparison (Ochir et al, 2018). Super Decision (SD) software 20.8 is used to assess weighting accuracy (Faisal & Ahmed, 2018). The consistency ratio of our AHP matrix is 0.0123.…”

“…The consistency ratio of our AHP matrix is 0.0123. The criteria weight of the study is acceptable because consistency ratio is less than 0.1 (Alkhatib et al, 2019;Faisal & Ahmed, 2018;Ochir et al, 2018;Saaty, 2008;Tupenaite et al, 2017)…”

GIS based modeling of GWQ assessment at Al-Shekhan area using AHP and SAW techniques

“…AHP technique was fi rstly developed by (Saaty, 1980(Saaty, , 2008. This technique can be used in different applications (Faisal & Ahmed, 2018). This technique uses pair wise comparison to derive the relative weights of parameters.…”
