It is the height of the free surface of water above a given point beneath the surface. [4] Pumping level is the level of water in the well during pumping. [8] Specific capacity is the well yield per unit of drawdown. [8] Static level is the level of water in the well when no water is being removed from the well by pumping. [8]
The Nierji Dam (Chinese: 尼尔基水利枢纽) is an embankment dam on the Nen River just north of Morin Dawa and on the border of Inner Mongolia and Heilongjiang Province, China. The dam was constructed between 2001 and 2006 for several purposes to include hydroelectric power generation, flood control, navigation and water supply.
A barrage dam can be used to divert water for irrigation needs or limit the amount of water downstream. In most cases, a barrage dam is built near the mouth of the river. The site of dam construction needs to be thoroughly investigated to ensure that the foundation is strong enough to support the dam and has low possibility of failing. [2]
In 2022, Nigeria lost more than 600 people and farmlands to the worst flooding in a decade following heavy rain and after Cameroon released water from Lagdo dam.
It can hold water up to 118 feet. The dam is 5,511 million cubic feet. The total length of the dam is 3 km It irrigated around 65,000 acres of areas in the northern part of the Nanguneri Taluk and Thisayanvilai and southern Veeravanallur, Karispalpatti, which are not irrigated by Pachaiyaaru in Tirunelveli district. The downstream joins River ...
The sill level of river sluices of the dam is at 450 feet (137 m) MSL. Nearly 90 TMC of water from the dead storage can be released from the river sluices to the downstream river tail pond during drought periods and further pumped to the adjacent right bank canal by constructing a pumped storage hydroelectric power (PSHP) station. The PSHP ...

Considerations are being made. A water body called Nachan Dam was selected for this purpose. Its viability and efficiency of water supply is currently being examined. [11] On October 31, 2020, the 31st gate of the barrage got bent because of pressure exerted by water, leading to a massive water outflow. [12]
