Abstract

Landslide susceptibility mapping is essential for land use planning and decision-making especially in the mountainous areas. The main objective of this study is to produce Landslide susceptibility maps (LSM) at Dalahoo basin, Iran using two statistical models such as an index of entropy and Logistic Regression and to compare the obtained results. At the ﬁ rst stage, Landslide locations identiﬁ ed by Natural Resources Department of Kermanshah Province is used to prepare of LSM map. Of the 29 lanslides identiﬁ ed, 21 (≈ 70%) locations were used for the Landslide susceptibility maps, while the remaining 8 (≈ 30%) cases were used for the model validation. The Landslide conditioning factors such as slope degree, slope aspect, altitude, lithology, distance to faults, distance to rivers, distance to roads, land use, and lithology were extracted from the spatial database. Using these factors, Landslide susceptibility and weights of each factor were analyzed by index of entropy and Logistic Regression models. Finally, the ROC (receiver operating characteristic) curves for Landslide susceptibility maps were drawn and the areas under the curve (AUC) were calculated. The veriﬁ cation results showed that the Index of Entropy model (AUC = 86. 08%) performed slightly better than conditional probability (AUC = 80. 13%) model. The produced susceptibility maps can be useful for general land use planning in the Dalahoo basin, Iran.
