  • Evaluation of PQ Applications in progress by Consultants.

4.    Hydraulic Model Studies
Hydraulic model studies were carried out for Dasu Hydropower Project in order to assess/confirm the design of the project. These studies included construction of a scale model of the project components and their performance through operation with properly scaled discharge. The facilities for these tests are available at Hydraulic Research Station, Nandipur, where the studies were conducted by the WAPDA Model Studies Cell, Irrigation Research Institute, Lahore.
The following models have been prepared and tested:


I.    Comprehensive Model at a Scale of 1:80
i.    Main dam including the spillway with 8 bays and 9 No. low level outlets.
ii.    Flushing tunnels
iii.   River channel reach of about 7Km


II.    Sectional Model of Spillway at a Scale of 1:50 & 1:20
This model of the spillway was comprised of three bays, constructed in transparent Plexiglas, to observe the flow conditions and make elaborate measurements of hydraulic parameters.


III.    Sectional Model of Low Level Outlet at a Scale of 1:40
In this model, a single low level outlet was constructed with transparent material, where the behavior of flow at different discharges was observed and necessary hydraulic measurements recorded.
Comprehensive technical reports prepared by the WAPDA model studies cell, which include all the observed data, photographs of different tests, and recommendations/ conclusions regarding the hydraulic adequacy of the project components.

Current Status
•    International Panel of Experts (IPoEs) visited Nandipur Research Institute and observed demonstration of models.
•    In the light of comments received from IPoEs, few modifications are being done in sectional models.
