Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater.Recharge is the primary method through which water enters an aquifer.
Using Figure 3 and knowledge of the upstream and downstream conditions and the depth values on either side of the gate, a general estimate of the profiles upstream and downstream of the gate can be generated. Upstream, the water surface must rise from a normal depth of 0.97 m to 9.21 m at the gate.
Only the upstream depth needs to be measured to calculate the flow rate. A free flow also induces a hydraulic jump downstream of the flume. Submerged flow occurs when the water surface downstream of the flume is high enough to restrict flow through a flume, submerged flume conditions exist. A backwater buildup effect occurs in a submerged flume.
Typically, over time the meanders gradually migrate downstream. If some resistant material slows or stops the downstream movement of a meander, a stream may erode through the neck between two legs of a meander to become temporarily straighter, leaving behind an arc-shaped body of water termed an oxbow lake or bayou. A flood may also cause a ...
Upon completion, Diamer-Bhasha dam would (i) produce 4800 megawatts of electricity through hydro-power generation; (ii) store an extra 10.5 cubic kilometres (8,500,000 acre⋅ft) of water for Pakistan that would be used for irrigation and drinking; (iii) extend the life of Tarbela Dam located downstream by 35 years; and (iv) control flood ...
The water in this stream forms varying currents as it makes its way downhill. In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry.
Ghazi-Barotha Hydropower Project (Urdu: غازى بروتھا) is a 1,450 MW run-of-the-river hydropower project on the Indus River in Pakistan. It is located about 10 km (6.2 mi) west of Attock in the Punjab province.
It is situated downstream of the confluence of the Jhelum and Chenab rivers. It is situated some 25 kilometres (16 mi) from the city of Jhang [1] [2] near the city of Athara Hazari where the River Jhelum flows into the River Chenab. It was one of the 7 link canals to be built under the Indus Water Plan of Pakistan.
