Scope of Stu!1. Hydrodynamic studies
To develop complete mathematical model for heat dispersion before
and after the plant is operated, including the influence of jetties. Simulate the flow conditions prevailing at the site based on the
bathymetry, and tidal conditions. Predict the flow conditions at site considering the withdrawal from the
proposed intake channel and discharges from the outfall at proposed
location for following for spring and neap tidal conditions.
2. Thermal dispersion studies Thermal & sedimentation modeling to study the dispersion of effluent
and to confirm the intake/outfall locations from recirculation
considerations. Study of various alternatives !hannel/Pipe line"to be carried out and
to arrive at an appropriate scheme for the discharge of the effluent.
Predicting temperature variations at the proposed outfall location and#ecommended location of the intake and e$haust cooling water.
3. Sediment transport Studies To conduct study of sediment transport include but are not limited to"
the number, the dominant direction and the time re%uired to settle prior
to and after power plant operation.
