Abstract

Landslide is one of the major natural hazards the world is facing. It happens as a result of both manmade
as well as natural factors. It causes severe effects on the environment as well as for the mankind. The main
triggering factors of landslide are rainfall/snowfall, tectonic activities and human activities. There are many
methods adopted for controlling landslides. The study is to know the application of geo-textiles in slope
stabilization.Ooty is one of the main areas in India which is prone to landslides. Landslides cause severe damage
to the life and property every year. The present study will be attempted in lake area. It is planned to collect
1.5m3 of soil sample from the landslide site and Physical, chemical and Engineering properties of the soil are to be
tested in the laboratory. To understand the application of geo-textile for soil erosion and slope stabilization,
laboratory models will be created, and the soil will be tested by varying the slope and rainfall intensity. The
main objective of our study is to measure the effect of slope and runoff on soil loss An automatic rainfall simulator
will be designed, considering the local conditions.Experiments will be conducted on a model of 2.0m length and
1m width with variations in slope. The collection trough will be made of size 1.0 x 0.3 x 0.3m below the
experimental model. A sprinkler system is planned to be set up to produce artificial rainfall. The water supply will
be given from an overhead water tank by adjusting a valve. For different intensity of rainfall by providing a
pressure gauge, with this experimental setup and the sample collected, test will be collected to know the soil
erosion quantity.
