Environmental flows describe the quantity, timing, and quality of water flows required to sustain freshwater and estuarine ecosystems and the human livelihoods and well being that depend on these ecosystems. In the Indian context river flows required for cultural and spiritual needs assumes significance. [1]
The River Continuum Concept is based on the idea that a watercourse is an open ecosystem that is in constant interaction with the bank, and moving from source to mouth, constantly changing. [4] Basis for this change in the overall system is due to the gradual change of physical environmental conditions such as the width, depth, water, flow ...
The Tana River Delta is the second most important estuarine and river delta (deltaic) ecosystem in Eastern Africa, comprising a variety of freshwater, floodplain, estuarine and coastal habitats with extensive and diverse mangrove systems, marine brackish and freshwater intertidal zone (intertidal areas), pristine beaches and shallow marine ...

[12] [13] River ecosystems are part of larger watershed networks or catchments, where smaller headwater ...

Physical properties of aquatic ecosystems are determined by a combination of heat, currents, waves and other seasonal distributions of environmental conditions. [13] The morphometry of a body of water depends on the type of feature (such as a lake, river, stream, wetland, estuary etc.) and the structure of the earth surrounding the body of water.
