Dams are ofen built along the course of a river in order to control the amount of discharge. Water is
held back by the dam and released in a controlled way. This controls fooding.
Water is usually stored in a reservoir behind the dam. This water can then be used to generate
hydroelectric power or for recreaton purposes.
Building a dam can be very eixepensive.
