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.

The 'alikpapan 'ay which occupies an area of ()* +m has

ma$imum depth that varies from m at the head Sepaku" to -* m in

the entrance of Teluk aru.

2. Soil Condition

Swamp land covered with mangroves. ight yelowish silt and clay andfine sand with patches of coarse sand in between, are poorly sorted

with highly variable skewness.

3. Rainfall and Temperature

Strongand erratic rainfall confined largely to 0une12ctober. The climate is hot and humid from 3pril till 2ctober and pleasant

during brief winter from 4ecember to 5ebruary.
