The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
The rise in water level at the Mullaiperiyar Dam poses a threat due to the potential for structural failure, as the dam was built in the early 20th century and may not withstand extreme pressures from excessive water. Additionally, heightened water levels increase the risk of seepage and erosion, which can compromise the dam's integrity. Concerns about the dam's safety are exacerbated by geological factors, including the seismic activity in the region. Therefore, monitoring and managing water levels is crucial to ensure the dam's stability and prevent catastrophic failures.
Beavers build a lodge. This is entered from under water but is above water level inside. A dam is built to control the water level.
Dam- a barrier constructed to hold back water and raise its level. used for electricity or water supply. Levee- a structure designed to prevent or control a flood
