Compensation of KHEP impact on NJHEP due to Dudhnial and Kohala Projects

CWC’s has contrived in the end of its report an offsetting mechanism of reduction of energy at NJHEP due to implementation of KHEP by referring to the alleged Dudhnial and Kohala hydroelectric plants.


Pakistan disagree with such thoughts based on merely some information possibly shared in the past about the planning of the Dudhnial project as storage works. Dudhnial HEP was initially conceived in early 80s as a storage project incorporating a 210m high dam with about 9km long tunnel to tap a total head of more than 300m. The project parameters were based on a desk study carried out in the offices of WAPDA. Till 1980 to date the project has to undergo the pre-feasibility and feasibility studies so that the configuration of the projects may be finalised and it may be decided whether the project would be feasible as a storage or run-of-river scheme.


It was checked and found, using satellite images and SRTM DEM, that construction of 210m high dam at Dudhnial would inundate about 30km of upstream river reach till Kel which amounts to inundation of the native population and relocation of the road that would become part of the reservoir. The inundation would also submerge Sharda village which is an ancient Buddhist monastery.

Inundation due to Dudhnial Dam with 15 m Height.

Sindh Water Sector Improvement Phase1

Selection Based on Soil Texture Seepage losses mainly depend on the soil texture through which

an irrigation channel traverses. Thus soil texture has been taken as the 2nd but prime criteria for the selection of sample channels. In order to identify various soil texture types in project area, soil texture maps developed by Planning Division of WAPDA on 1:250,000 scale have been studied. These maps classify project land with following types of soil textures;

Coarse (Sand, loamy sand) Moderately Coarse (sandy loam, fine sandy loam) Medium ( loam, silt loam, silt) Moderately fine (sandy clay loam, clay loam, silty clay loam) Fine (sandy clay, silty clay, clay)
