River channel adjustment to floodplain management.

The main elements of the fluvial hydrosystem — the river basin, river channel and flood-plain — are bound together by three-dimensional, time dependent exchange of matter and energy, which determine the ecological system with its interactions and successions (Amoros and Petts, 1993). Thus, the main channel and the floodplain are inseparable and floodplain management implies also the adjustment of the river channel.
