摘要

The landslides that have been taking place in a certain area of Uttarkashi are the subject of this particular piece of literature, which focuses on the topic. Earthquakes and flash floods are two more natural threats that have been brought up in this series of discussions. As a consequence of the increase in the number of activities carried out by humans, the number of landslides that have taken place in these areas has increased. This will make it possible for the required development activities to be carried out in the later stages of the project. It is required to split areas that are prone to risks into various zones in order to establish the amount of the influence that these dangers have. This is done in order to determine the extent of such an impact. Field data, Google Earth, landslip location data, eight Landsat satellite imageries, toposheets prepared by the Survey of India department, and the development of several thematic layers such as slope, altitude, structure, geology, drainage, land use, and land cover have all been utilized in the process of hazard zonation mapping. These hazard layers include slope, altitude, structure, geology, drainage, and land cover. The weight of evidence method was utilized in order to develop LHZ. This was accomplished by combining all of the spatial layers that are regarded to be a part of the GIS domain. A number of separate zones have been established throughout the region in accordance with the landslip threat zonation map. In order to validate the Landslip hazard zonation map, the Landslip Inventory map of the study region was utilized. This allowed for the validation of the map. In addition, the danger zonation map has been validated by mathematical analysis in addition to being tested in the field.
