Baozhusi Dam
Encyclopedia
The Baozhusi Dam is a gravity dam on the Bailong River
, located 23 km (14 mi) northwest of Guangyuan
in Sichuan Province, China. Construction on the dam began in 1984, the generators were operational between 1996 and 1998 while the rest of the facilities were complete 2000. The dam was constructed for hydroelectric power generation, flood control and water supply for irrigation and industrial uses. The 132 m (433 ft) tall concrete gravity dam creates a 2550000000 cubic metre reservoir
with a surface area of 61.2 km² (24 sq mi). On either side of power station at the dam's base, there are two gate-controlled chute spillway
s. Beside them are two pairs of intermediate sluice-controlled orifice openings. Below the left intermediate opening are two bottom sluices. The total discharge capacity of the spillways and openings is 16060 m3/s. The dam's power station contains 4 x 175 MW Francis turbine
-generators which are afford a maximum hydraulic head
of 103 m (338 ft) given the dam's height.
Bailong River
The Bailong River is a river in the East China Sea basin of China. In August 2010, due to heavy rains and landslides the river overflowed its banks in Zhugqu County, Gansu, causing extensive damage and killing over a thousand people....

Reservoir
A reservoir , artificial lake or dam is used to store water.Reservoirs may be created in river valleys by the construction of a dam or may be built by excavation in the ground or by conventional construction techniques such as brickwork or cast concrete.The term reservoir may also be used to...

Spillway
A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically being the river that was dammed. In the UK they may be known as overflow channels. Spillways release floods so that the water does not overtop and damage or even destroy...

Francis turbine
The Francis turbine is a type of water turbine that was developed by James B. Francis in Lowell, Massachusetts. It is an inward-flow reaction turbine that combines radial and axial flow concepts....

Hydraulic head
Hydraulic head or piezometric head is a specific measurement of water pressure above a geodetic datum. It is usually measured as a water surface elevation, expressed in units of length, at the entrance of a piezometer...
