Environmental flows refer to water that is left in a river system, or released into it, for the specific purpose of managing some aspect of the health of the ecosystem. Past water abstractions, or other flow manipulations, made without thought for the impacts on the river ecosystem or on people depending on that ecosystem, have resulted in a wide range of economic, social and ecological repercussions. Water developments can be expected to continue, however, and water shortages will become a major and growing threat to national and global security. If both present and planned developments include informed management of river flows, then water resources can be used whilst holding negative impacts at a level that is acceptable to society. Such managed flows, usually called Environmental Flows or Instream Flows, can be used to achieve conservation or recreational aims, ensure continued subsistence use of river resources, or simply to ensure a better functioning and healthier ecosystem.
Ecohydraulics provides the vital link between river flow and the biota of the river system, describing the habitat available for aquatic organisms and the flows required to meet their needs.
