Environmental flow

Environmental flow

Environmental flow is the amount of water needed in a watercourse to maintain healthy, natural ecosystems. The term is used in the context of rivers which have been dammed, with most or all of the flow trapped by the dam — the failure to provide an environmental flow can have serious ecological consequences.

According to the Global Environmental Flows Network,

Only a few countries, such as Australia, South Africa, and the UK have integrated the concept into water management.
