| Summary: | Bottom intake is a simple structure which is consist of a channel on the river
bottom vertical to the river flow and a screen on top of the channel. Kamanbedast
and Bejestan (2008) was conducted the research to know the optimum intake
slope by using physical model. The optimum intake slope was taken by the ratio of
discharge entering the intake to the discharge fromupstream. Based on 4 slope
variation (10, 20, 30 and 40%), it is obtained the optimum slope at 30%.
Considering the limitation of bottom intake slope variation, it is possible that the
optimum slope occurs at the range between 20 to 30%or 30 to 40%.
The present research uses 3-dimensional numerical model by the support of
Flow3D programming package. The simulation was conducted at various slope
with the accuracy of 1%.
The result shows the optimum slope at 28% with the discarge ratio as 28,3%. |
