Landslide

Landslides are among the most common natural hazards and are the most damaging, leading to a variety of human and environmental impacts. Landslide is the result of a wide variety of processes which include geological, geomorphologic, and meteorological factors. Landslides triggering factors including geological, hydrological, topographical factors and loading conditions. From Garg to the Himalayas, covering an area of 30% of the world's long land, resulting in a large number of different and complex

LANDSLIDES Introduction The term ‘landslide’ includes all varieties of mass movements of hill slopes and can be defined as the downward and outward movement of slope forming materials composed of rocks, soils, artificial fills or combination of all these materials along surfaces of separation by falling, sliding and flowing, either slowly or quickly from one place to another. Although the landslides are primarily associated with mountainous terrains, these can also occur in areas where an activity

PROBLEM STATEMENT: Landslides impact thousands of people and damage billions of dollars of infrastructure each year. Mitigation can be difficult and expensive when detailed risk and hazard maps are not available to local planners. For over 50yrs, the coastal population of Southern California has been increasing steadily and drastically. The rate of anthropogenic activities (construction of roads and other hillside utilities) under the banner of development has followed population growth resulting

consequences associated with different natural and man-made hazards. Among most of the natural hazards, Landslide is being prioritized as a matter of great concern as a result of its devastating nature. South-eastern part of Bangladesh is very much prone to this hazard with long history of instability since the people have been living there though there is not enough record of incidents. Landslides are frequently resulting in losses of both lives and properties which are being worsened with rapid and

applying the principles I have learned in this class when it comes to purchasing a home. This class has taught me the type of areas that are prone to mass wasting. I know that I should not purchase a house in the mouth of a canyon, on existing old landslides, and on or at the base of steep slopes. I also know that rain, loose soil, and steep slopes increase the likelihood for disaster dramatically. When it comes

Consequently, in future hazard surveys remote sensing could identify the land characterises of landslides in “cloud free areas” and use this data to direct traditional methods of field-data collection (i.e. helicopters) to “hot-spots” of greater landslide susceptibility. This report will explore and test this hypothesis using a large landslide dataset collected during the ‘Gorkha earthquake series’, Nepal, 2015. 1.1. Study area Nepal is situated on the Himalayan arc

Cuckmere Haven hosting approximately 450,000 visitors each year is a popular tourist destination particularly with views of the Seven Sisters chalk cliffs. It is situated in Sussex, South-East of the UK as shown in Figure 1. The Environment Agency has undergone discussions over restoring the Cuckmere estuary to a floodplain multiple times in the past but local residents have opposed this due to “concerns over the impact this would have on their homes and on business”. The task question I have chosen

River valley and is prone to landslides. This area is prone to landslide due to steep slopes, an addition of water, adding weight to the top of the slope or cutting support at the bottom, causing movement. The Plotterkill Preserve is a tributary of the Mohawk River that has steep slopes made of glacial till making it susceptible to landslides. It is an unstable hillslope with active parts. There are three main features to the hillslope: a southwest slump, a main landslide, and a creep slope. The southwest
