Landslide is considered one of the greatest natural hazards that causes high damage direct or indirect financial every year. One of the areas prone to natural factors in the occurrence of this watershed and from the North Country. One of the occurs Susceptible areas in watershed vaz. Landslide hazard zonation map was prepared by using AHP and 6 certainly factor, landslide index, weight factor, ...
Today, urban and regional issues related to sustainable development is a key challenge for policy-makers, planners and specialists in various disciplines. Geomorphologic studies can be useful and effective in analyzing and deriving acceptable means to assess the growth and development of the city, and to set criteria to determine the directions of urban development. Landslides ran...
Watersheds are changed positively or negatively as biotic and abiotic factors in natural circumstances impact them. Landslides, as a physical factor, one of the negative consequences on these catchments. Masoleh watershed, in North of Iran, is one of the susceptible areas to explode the natural landslides. In other to landslide hazard zonation, the Dempster-Shafer model is which is used has 14 ...
Introduction Geomorphological hazards posed as a potentially harmful phenomenon that most important ones are mass movements and landslides. The occurrence of natural hazards (including landslide) has imposed the serious impact on countries’ economic development, especially the third world countries. One of the most important tasks of applied Geomorphology, is to check the position and ...
Landslides are major natural hazards which not only result in the loss of human life but also cause economic burden on the society. Therefore, it is essential to develop suitable models to evaluate the susceptibility of slope failures and their zonations. This paper scientifically assesses various methods of landslide susceptibility zonation in GIS environment. A comparative study of Weights of...
A landslide hazard zonation is a division of the land surface into areas, and the relative ranking of these areas according to degrees of actual or potential hazard from landslides on slopes. Zonation from scientific research does not generally imply legal restrictions, but can be useful to those people who are charged with the land management, by providing them with information that is indispe...
the efficiency of three statistical models, ahp surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in chehel-chai watershed in golestan province, iran. in current study the hazard map was prepared according to the top model of landslide hazard map. chehel-chai watershed is located as one of go...
We are designing a system to forecast rainfall-induced landslides in Italy. The system is based on a set of rainfall thresholds for the possible initiation of landslides, and an ensemble of small scale landslide hazard and risk zonations. Rainfall thresholds include existing and new, national, regional and local empirical thresholds of the intensity-duration (ID) and normalized-ID types. The ne...
