Yes there are many dams and more dams are being built. i dont know how many and i would like to know.

hydroelectric power.
400 factories have been build in China since 2000
There are many river dams, many are built to create hydro power.
There are not so many dams because it will cost lots ,floods,we think that dams will help us in generations to come but that doesn't happen mostly and it will also destroy the habitats
At independence, in 1947, there were fewer than 300 large dams in India. By the year 2000 the number had grown to over 4000, more than half of them built between 1971 and 1989. India ranks third in the world in dam building, after US and China. While some of these dams were built primarily for flood control, water supply, and hydroelectric power generation, the primary purpose of most Indian dams remains irrigation.

whats the point in putting the qustion on with no answer
the dam built on jhelum is mangla dam
About 34,000 Corvettes were built.
Downstream of the dams the river would get narrow and shallow and upstream of the dams the river would get wide and deep. In between the dams would vary between the two depending on how much water each dam releases and lakes and ponds would probably form between the dams.
