Project: Phukot Karnali Hydroelectric Project 

Assignment: Sedimentation Study of Phukot Karnali Hydroelectric Project

Location: Kalikot District, Nepal

Client: NEA Engineering Company Limited

Duration:  July 2019 to November 2019

Project Description: Phukot Karnali Hydroelectric Project is a Peaking RoR project of installed capacity of 426 MW. The project is located in Kalikot district. Its proposed intake is approximately 35 km upstream of Upper Karnali HEP (900 MW) and its powerhouse site is approximately 7 km upstream of Karnali and Tila River confluence. The project has approximate catchment area of 16,764 km2 and uses design discharge of 278 m3/s. It generates total annual energy of 2510.02 GWh.

Scope of Services:

1. Collection, gathering and transportation of all the materials and equipment;
2. Appoint and train the site technician to carry out the sampling by depth integration method and in different frequencies;
3. Carry out the concentration analysis at the lab established in the site;
4. Transportation of the dry sediment samples (after concentration analysis) to the lab at Kathmandu and perform the Mineral and Particle Size Distribution analysis;
5. Compilation of the PSD Data and Preparation of the sediment rating curve;
6. Monthly progress report preparation and submission;
7. Equipment used to take samples using point sampling method:
   a) USGS Depth Integration Sampler with four-wheel crane system;
   b) Filtration system, Drying Oven and weighing accessories;
   c) Microscope for Mineral content analysis; and
   d) Particle Size Analyzer for Particle Size Distribution Analysis.
