Abstract:

In Kerala majority of the hilly or steep sloped regions are under the elevated risk of soil erosion. It is one form of soil degradation induced mainly by the actions of wind or rain. The factors affecting erosion includes land use, geology, geomorphology, climate, soil texture, soil structure, vegetation etc. Soil erosion may be a slow process that continues relatively unnoticed causing loss of fertile top layer soil, which is good for plant growth, and it may reduce the soils ability to absorb and store water, which is in increased rate results in landslides, debris flows, rock fall etc., in the sloped regions. So it is essential to put as much as effort as possible into actions especially in slopes along with highway that will stop the soil from washing away by suggesting methods to control it after the analysis of the stability of that slopes. ‘Nadukani Hills’ is one of the frequent land slide region in Kerala. The stability analysis on that region is necessary. One of the method for stability analysis of slopes is by using the software GEO5. Using this software, we can solve most geotechnical tasks. By using the software’s output, factor of safety and comparing it with the standards, we can analyze the stability of slope against sliding. The stability analysis on Nadukani Hills shows that the areas are highly susceptible for erosion. The control measure using reinforcements and anchors also suggested based on the analysis.
