Hydropower draws mechanical energy from rivers, [[wave power plant|ocean waves]] and [[tidal power|tides]]. [[Civil engineering]] is used to study and build [[dam]]s, [[tunnel]]s, [[waterways]] and manage coastal resources through [[hydrology]] and [[geology]]. A low speed [[water turbine]] spun by flowing water can power an [[electrical generator]] to produce electricity.
