Flood zonation mapping is one of the priorities for the soil and water management, which Remote Sensing (RS) capabilities are very applicable to this issue. The main objective of this research was study of accuracy of the Object oriented and Pixel based methods for flood zonation mapping in the Taleghan River basin. Therefore, the Sentinel 2A satellite image of the study area classified using s...
Landslide susceptibility zonation mapping is necessary in urban and rural development planning. So far different methods are presented for Landslide susceptibility zonation. In this study, using statistical method of Frequency ratio and Analytical Hierarchy Process (AHP) based on paired comparison and intervention based such as slope, aspect, altitude, geology, land use, Normalized vegetatio...
more than 30% of iran's land is formed from mountainous areas. so each year, landslides cause damages to structures, residential areas and forests, creating sedimentation, muddy floods and finally deposit the sediments in reservoir dams. therefore, for preventing of this damages and expressing the sensitivity rate of hillslopes, landslide hazard zonation is considered in prone areas. the p...
natural hazards are among destructive agents that annually take thousands of lives and impose devastating damages in iran. spotting such a high risk areas can help reducing the amount of their probable risk. a 1:500000 liquefaction and landslide hazard zonation map developed for the southern shoreline of the caspian sea. this geotechnical hazard map divides the study area to 15 hazard classes (...
