Question: Two rectangular sharp crested weirs are to be constructed on an overflow trapezoidal dam which has an estimated flood discharge of 2 6 0 0

Two rectangular sharp crested weirs are to be constructed on an overflow trapezoidal dam which has an estimated flood discharge of

2600 \frac{m^{3}}{s} .

The dam shall also has

6

sluice gates

) = (0.80 m

wide and

4 m

high. Assume that sluice gates behave like orifices. The top of the sluice gates is at elevation

50 m,

the crest of the weir is at elevation

110 m

and the recorded elevation of the water is at elevation

115 m .

.

Compute the designed length of each weir if the dam has to discharge flood at maximum and all the sluice gates are open using Francis Formula neglecting velocity of approach.

.

When the sluice gates are closed and the two weirs are open, find the time in minutes to lower the water surface by

3 m

if the reservoir upstream has an area of

50

hectares.
