... at Karavallikkombai to Sholaikkadu at the top is selected for the present study. The hill is situated at a fault zone which is extended from Mettur dam, Salem district, Tamil Nadu. In this study, undisturbed soil samples were collected from 10 landslide locations and tested for its index and engineering properties...

.... Earthquake shocks have been felt locally at Mettur Dam in recent years on an active fault. Bauxite deposits being mined at 1800 m elevation on top of the Shevaroy Hills 60 JOHN C. GRADY have been dated mid-Miocene in age (Vaidyanadhan, 1967). The climate at the ].5 km bauxite deposits is temperate...

.... In maps 58 B/7 + 8 + 12 the orographic axes are aligned mainly WNW-ESE, while there is a 60 km fracture aligned NNW-SSE, and a group of echelon north-south fractures extending for 55 km. More caution is required in the area of the Mettur dam where the NE-SW strike ridges predominate over a subdued...

... of a river like Cauvery. It is here that, a massive concrete dam has been constructed across the river, creating the Mettur reservoir. Senile course over the Tamil Nadu plains Leaving Mettur and still keeping a straight, narrow course it captures the course of the river Bhavanijoining it from the west. From...

..., in the Cauvery basin, the erosion rate at Bhavani, downstream of Mettur Dam, was 100 tonnesjkm2jyr whereas at lower Anicut, 150 km farther downstream, it was only 40 tonnes/km2/yr. Table IV shows the various fluxes and erosion rates obtained for the rivers of the world. The Asian rivers show a very high erosion...

... between the Sivasamudram falls and the Mettur dam is at the rate of 2.67 m/km. Considering the above highly varied geomorphic characteristics and the imminent need for water resource-based developments and managements for improving the quality of life in the area, a detailed investigation has been carried...
