چکیده مقاله:

One of the environmental crisis are major natural hazards that threaten human life and property and injury is always harmful. Landslide hazard zoning is one of the ways in which that can with use it determine critical areas and the zoning map prepared in environmental planning to reduce damage caused by it. In the present study investigated the landslide occurrence hazard zonation in Kharv basin using information value model and Shannon entropy. The most important factors affecting landslides in the areas of research in order include distance from the river, shelves, shape, slope, aspect, and distance to fault, land use, elevation and geology. Map factors affecting landslide was cut off by landslide occurred map ,the following factors were weighted using the value of the information and criteria using the Shannon entropy index, and finally by using a combination of different factors landslide risk map was prepared. Results show excellent accuracy of model verification (AUC 92/0) to predict landslides in the study area. So carefully mapped 92%, a good performance in predicting the risk of landslide.
