Why is weather forecast important for an engineer working on a river dam
Answers
Dams and the water reservoirs they hold back are essentially like bathroom sinks. If the faucet discharges more water than the drain can handle, the sink will eventually overflow and ruin the floor.
But dams and reservoirs have an additional handicap: We can never be certain how much water nature will pour into the watershed upstream. And if too much pours in, it’s not just a floor that’s at risk, but the integrity of the dam holding back the water — and the safety of people living downstream if the dam bursts or levees are overwhelmed by high flows.
So engineers wrote dam operating rules — often embodied in water control manuals — that dictate how much empty space must be maintained in reservoirs to contain floods. These usually depend on the season and local climate: more space in winter and spring, even if no storms are expected; less in summer and fall. In some cases, the rules also prevent operators from drawing reservoirs too low, in order to ensure enough water for urban and agricultural users and environmental requirements like adequate flows for fish. And engineers wrote the rules conservatively to handle uncertainty.
Answer:
bcos according to it he can work or continue his work or else suddenly if rain comes or suddenly if flood so it is important for an engineer to see weather forecast
