Ranapratap Sagar Dam : A 40 m. high straight gravity dam of stone masonry built across river chambal with 19 bays of spillway. Power house having 3 units of 43 MW each, located on left bank had problems of stability due to clay seams present in between Quartzite layers.

Contribution : Stability Analysis, Stress Analysis, Design of spillway and detailing of project was carried out. Tension cables were designed for the stilling basin and the power House.

Koyna Dam Project : The project comprised of a 800 m long ,110 m. high rubble concrete dam, an intake structure, an underground powerhouse, a transformer hall, Control valve house and a tail race tunnel.

Contribution: The dam was designed for a nominal earthquake (0.05g). It suffered a very severe earthquake shock(0.63g) which caused some distress, mainly to the overflow section. The studies for the strengthening the dam and the design of the remedial measures was carried out. A computer program was developed for this purpose. The case history written by me has been published by ICOLD.
 

Contribution: Complete design and detailing of the chute spillway including anchorage in the foundation, horizontal and vertical curves. Physical model studies were supervised and changes incorporated in the profile.
 

Karnali Dam (Chisapani), Nepal: A 270 m .high dam with an underground powerhouse was under investigation in Nepal by a consortium of three companies from Canada called HPC(Himalayan Power Consultants).

Contribution: Plate jacking tests using bore hole extensometers and in-situ stress measurements by overcoreing technique were carried out. A computer program to calculate the principal stresses in magnitude and direction was developed for the purpose.
 

Pancheshwar Dam Project: A high dam with an underground powerhouse was under investigation in Nepal by a consortium of multi-national companies called PACO( comprising of Morrison Knudsen, USA, EPDC, Japan, Electro consult, Italy and Monenco Consultants, Canada.

Contribution: Organized field tests for modulus of deformation, using plate jacking and Goodman jack techniques, besides carrying out laboratory tests on Rock samples for physical and engineering properties.
 

Nathpa Jhakri Hydro Electric Project: The project comprises of a 40 m. high concrete gravity dam, 29 km. long tunnel and an underground powerhouse, four large underground de-silting chambers.

Contribution: Rock mass Classification studies in different reaches of the tunnel, measurement of in-situ stresses, deformation modulus using different techniques.Removal of large boulders and debris from the river bed to clear its passage.
 

Srisailam project(A.P): Located in Andhra Pradesh across river Krishna, Srisailam Dam is 160 m. high straight gravity concrete dam. It has a spillway, a powerhouse and a non-overflow portion.

Contribution: Complete design of the concrete dam, spillway land the power dam were carried out. back water computations, Energy dissipation arrangement and the layout was finalized.
 

Lakhwar Dam project(U.P): A 204 m. high concrete dam is proposed across river Yamuna in Utter Pradesh. The foundations comprised of quartzites and states and the junction of the two rock types was problematic.

Contribution: A number of in-situ tests were carried out to determine the rock mass characteristics required for design. Instrumentation of support system was carried out in the underground powerhouse.
 

Salal project(J&K): The project has an earth and rockfill dam and a concrete spillway both about 100 m. high from the deepest river bed level. The spillway was located on a dolomite ridge.

Contribution: A record number of field tests were done to obtain the shear strength of rock joints. Measurements of roughness were carried out in the field. It was possible to reduce the conventional factor of safety on the basis of enormous data generated by testing.
 

Chukha Project(Bhutan): The project had a 40 m. high concrete gravity dam, two inclined pressure shafts and underground powerhouse. The project is located on river Wang-chu

Contribution: Instrumentation of the underground powerhouse to measure the rock loads and deformations was carried out.
 

Tala H.E.Project (Bhutan): The project was under investigation, envisaging a high dam, a tunnel and an underground powerhouse.

Contribution: Drilling and field testing for characterizing the soils and rocks was organized.
 

Chamera Hydro electric project(H.P): The project comprises a 121 m. high arch gravity dam with an integral spillway, a 9.5 m. dia tunnel, a powerhouse with 3 x 180 MW capacity and a tail race tunnel.

Contribution: Investigation for the project was carried out under the supervision of Canadian agencies with a funding from CIDA. All procedures and methodologies used were as per International Standards.
 

Tehri Dam project: The project envisages construction of a 260.5 m. high rockfill dam and an underground powerhouse of 2000 MW capacity which would be installed in two stages. It has four large diversion tunnels of 11 m. dia finished. The chute spillway has two systems. Four head race tunnels led to a surge shaft from where penstock carry the water to turbines.

Contributions: In-situ rock mechanics tests, deformation characteristics of the rockfill material and suitability of materials of construction was established, shear strength characteristics were determined.
