Every year, due to population growth and economy development, land uses and land covers are changing. The various types of land uses have significant roles on components of water balance of a watershed. The simulation modeling has the capability to predict floods, to evaluate land use impacts on floods, and to make decision in watershed management. In this research, the effects of land use chan...
Extended abstract 1- INTRODUCTION Landuse change due to human activities is one of the important issues in regional planning. Considering the advantages and capabilities of the distributed hydrological models, they are appropriate for the survey of landuse changes as well as their quantitative estimates. Land evaluation methods are used to determine the compatibility of the land according to ...

Identification of susceptible areas to landslide occurrence is one of the basic measures for reduction of the possible risk and hazard management. The main goal of this research is to compare the applicability of two statistical landslide hazard zonation models, valuing area accumulation and Analytical Hierarchy Process (AHP),in Ziarat Watershed, Gorgan, Golestan Province.In a review of previou...
Ziarat drainage basin, in the southern part of Gorgan city, is exposed to mass movement, especially landslide occurrence, due to geologic, geomorphologic, and anthropogenic reasons. The objectives of this study were to predict landslide susceptibility and to analyze the effective factors using rare events logistic regression. In view of this, the map layers of the variables including geology, l...
