Dams and Reservoirs topics included here: Dams types, geological characters for investigation, reservoirs and their types. Dams and reservoirs are both structures related to rivers. Dams are built on rivers to store water for various reasons, such as hydroelectricity, irrigation, and flood control. Reservoirs are formed behind dams.  Here are some types of dams: Arch dam: A good choice for small canyons with sturdy flanks that can withstand the thrust created by the arch action. Gravity dam: A solid structure constructed across a river to create a reservoir on its upstream. It uses the... Show more
