Application of Analytical Hierarchy Process (AHP) to Landslide Susceptibility Mapping at Korek Anticline, Northeast of Iraq

Noor Aqeel Shams | Hamed Hassan Abdullah

Abstract: Landslide problems are abundant in the korek anticline due to a unique combination of adverse geological conditions. To control such problems, systematic studies of landslides are necessary, including inventory mapping and risk assessment. The purpose of this study is to produce landslide susceptibility maps by using analytical hierarchy process (AHP). At first, landslide locations were identified by aerial photographs and field surveys. seven parameters were used in the AHP method gives value from 1 to 9 according the most important factor and each one was separated into five categories ranging from 1 to 9, representing their specific conditions derived from the investigation of the landslides. Lithology, Slope angle, TPI, lineament Density, TRMM, drainage density and Curvature of the study area are considered as the landslide conditioning parameters. This procedure helps in the produce of the final susceptibility map. five levels of relative hazard are defined on a landslide susceptibility map (1) very low, (2) low, (3) moderate, (4) high, and (5) very high hazard. From the field observation of the study area, 18 stations were selected and this station were represented on maps of study area, some of them suffer from different type of failure and after studying and preparing the model it appears that this stations lies within high risk classification to very high risk. The hazard increase toward the top of korek anticline limb and decrease toward the edges of limbs.
