The DCS did the Hydraulic Modelling of Headworks of Rasuwa Gadhi Hydroelectric Project (111 MW). This includes the verification of current headworks design and work performance of the settling basin/Desander with flushing system currently proposed. For this project SMEC is the International consultant and China International Water and Electric Corporation is the contractor. The work is under CWE for the contractor. This Hydraulic model includes the Computational Fluid Dynamics (CFD) works to verify the current deign parameters.
