DAMS AND ITS DANGER LEVEL
Whenever there is excess rain, we are worried about the time of opening of
the dam shutters .
Why not just make wide openings below the danger level , at sufficient intervals and as many as required . Then whenever water level reaches high, it automatically
flow out slowly, incessantly without much force till the rain stops and the
inflow from catchment areas cease . Since the outflow is from top, naturally
the pressure of the outflow will be far less to cause any damage to he
surrounding areas and people . Great calamities can be prevented . Dams will be a blessing and not something to
be scared of in monsoon. The walls of
the dam need not bear any extra pressure
since only the stipulated level of water is maintained always . It will never
reach the danger level in the first place . What a great relief for the people,
for the government and for the water authorities .How many sleepless nights and
precautionary measures are undertaken before the shutters are opened . Only wen
the shutters are suddenly opened to let
out all the accumulated water , calamities occur .
Once the shutters are opened, the dams are drained
completely after heavy rains. By allowing water to flow out freely from the top
level, all the water up to the maximum level remain in the dam after the rain.
This will be sufficient till the next monsoon . No more water scarcity .
When the dams are built , at the danger
level , provide a reinforcement of lintel like concreting with
openings at intervals for water outflow.
For the existing dams, if large wide holes
are drilled out, the outflow is made easier .
Since TOP water have LESS PRESSURE , water management is done ell .
Hanging baskets with strong belts for the men who work with strong nets tied
below for additional security feelings . Compare this
water flow to the gushing of water from six or more shutters . What a
difference in safety measures .
