The pass consisting of successive basins
The successive basin pass is a very old principle which means that we have a lot of feed-back.
The principle of this pass is the division of the difference in height by the installation of successive basins in a row. The dimensioning of each basin depends on the requested energy dissipation related to the specimen of the migrating fish. One of the advantages of this type of fish pass is the high flexibility regarding the upstream and downstream water level.
