Abstract

This study deals with the application of geographical information system(GIS) datasets and methods to assess the landslide susceptibility in WadiHujran. The area has a rocky terrain and belongs to the Shaqlawa districtof the Kurdistan Region of Iraq. The region is placed towards theNortheast side of Erbil city. The region covers an area of 18.56 Km2(1856.1 ha) and consists of rough broken and stones. The watershed areais surrounded by North latitudes 36° 21' 53.514" to 36° 17' 49.7796" andEast longitudes 44° 17' 5.658" to 44° 20' 9.06". Three factors, namely themorphometric, geological, and environmental, were used to prepare thelandslide susceptibility index. The study made use of AHP method andprepared a landslide susceptibility map. Data related to geology,topography, hydrology, rainfall, and land use were used to prepare themap. Physical and statistical methods were used to validate the map. Aheuristic approach was incorporated to produce the final susceptibilitymap. ArcGIS software was used to generate the landslide zones. A totalof five landslide zones were generated, which varied from very lowlandslide zones (80.5) to very high landslide zone (84.5). The zones alsoincluded low landslide zone (1262.2), moderate landslide zone (1505.9),and high landslide zone (566.8), and the ratio of consistency in thepresent study was 0.06 AHP less than 1, and all the five zones in the studywere compiled landslide zonation estimated
