In this study, Vanak catchment because of high sensitivity to landslide was selected. Then with geological, topographic maps and field survey, Landslide hazard map was prepared using GPS as dependent variables. A total of 110 landslides were mapped in GIS out of which 77 (70%) locations were chosen for the modeling purpose and the remaining 33 (30%) points were used for the model validation. Th...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

The most crucial but difficult task in the analysis of the risk due to landslide hazard is the estimation of the conditional probability of the occurrence of future landslides in a study area within a specific time period given the presence of spatial and geomorphologic features. This contribution explores a modeling procedure for estimating that conditional probability. The procedure proposed ...

Landslides are a major geological hazard in Garhwal Himalayas, since they are widespread dynamic processes that cause damage, and even loss of life, every year. Development of urban areas, Highway construction and expanded land use in Garhwal Himalaya mountain regions has increased the incidence of landslide disasters. The enormous damage caused by landslides can be reduced by means of monitori...

Landslide awareness, especially in regions where natural disasters are always happening, is of the most extreme importance. To anticipate disaster, several statistical methods have been proposed, but it still unclear which one more accurate. However, few studies proposed a dependable method. These strategies considered rather indiscriminate this digital world every study based on new technology...
