Geomatic Techniques Based TOPSIS Method for Blajo Canal Evaluation

Abstract

Water is one of the world’s most important natural resources and has recently revealed several emergencies that are becoming national concerns. This research focused on the Iraqi water crisis because a huge percentage of Iraq's water is flowing from outside sources. particularly the problem of water shortages in the Wind River, using a GIS-integrated TOPSIS method to evaluate the Blajo Canal. Present channels were evaluated by TOPSIS, an MCDM technique that takes into account the separation between the positive and the negative points between the different options. The excellent alternative should lean toward the favorable while avoiding the passive. The results indicated that the Blajo Canal was spatially placed in alternative number 4, ranked number 3 by the TOPSIS method. This site is therefore close to arable areas and meets the criteria, although it is not the best place for it when compared with other alternatives.
