Guidelines for the Assessment of Environmental Flows in the Western Indian Ocean Region

Environmental flows assessments – or Eflows – seek to determine the quantity and quality of water and sediment flows necessary to sustain freshwater and estuarine ecosystems and the human livelihoods and wellbeing that depend on them.
