MISINFORMATION is circulating that large dams were drained during the flash flood period, but this is not true. An experienced engineer has stated that spreading such misinformation can cause public panic and should be avoided.
Large dams cannot be drained or
broken down. Water flows into the dam, and any surplus is released through the
spillway. If the water from these dams were drained, as someclaim, millions of
acre-feet of land would be flooded, and those areas would be washed away, he
explained.
Dams are designed to mitigate flooding.
When large volumes of water flow into the dam due to heavy rains, they hold
back millions of gallons of water, preventing it from immediately reaching
nearby residential areas and buildings along rivers and creeks.
Dams are built with spillways to release
surplus water into creeks or rivers after their capacity is calculated using
engineering technology.
At a time when it rains heavily, the
volume of water which exceeds the capacity of storage at the dam flows out from
the spillways. Moreover, the construction of dams aims to generate electricity,
irrigate croplands, supply drinking water to the people, and mitigate flooding.
If dams do not control water, people
may face unprecedented suffering more than the current incident, said the
experienced engineer.
Officials control water in the dams
systematically while repairing water control gears and draining out
agricultural water for croplands.
On 12 September, the water level at
the Mezali Diversion Weir reached 206.6 feet and continued to rise gradually.
Because of the opening of its valve shutters, the measuring marks at the
diversion weir did not change. An official from the facility stated on social
media that real-time updates on the dam’s measuring marks will be provided.
