Fishways for Downstream Migration

Fish Protection Technologies and Fish Ways for Downstream Migration, 2019
In order to ensure the downstream migration of fish, it is not enough to prevent them from entering the potentially hazardous parts of facilities; they must also be provided with an alternative path that will enable them to travel, actively or passively, from the headwater of a barrage to the tailwater without loss of time or risk of injury.

Reservoir effects on downstream river channel migration

Environmental Conservation, 2000
Human occupation and development of alluvial river floodplains are adversely affected by river channel lateral migration, which may range as high as several hundred metres per year. Reservoirs that reduce the frequency and duration of high flows typically reduce lateral migration rates by factors of 3 to 6.
