Boat waves, currents and grazing pressure can cause riverbank vegetation to degrade or erode. BESE-products aims to restore these ecosystems by overcoming the foundation threshold. BESE-elements for example can first of all serve as a 3d structure that decreases wave energy and currents. Secondly, they can provide shelter for young plants against grazing pressure from fish, crustaceans or birds. And at last, they have a temporary function, once the young plants have grown and formed their own 3d structure of roots and stems the BESE-elements degrade.
BESE-gabions mainly form a protection against grazing pressure. Boat waves and heavy currents still have an effect on the plants within the gabion as the 3d structure is not that dense as in the BESE-elements. Applying the BESE-gabions therefore works best on low dynamic locations. If a location is highly dynamic we advise you to use BESE-elements.
Lastly the BESE- mesh bags and BESE-breakwater can function both as a wave breaker, creating a low dynamic zone behind the structure. Plus the structure itself can serve as a settlement substrate for plants. The BESE-mesh bags and BESE-breakwater do not offer protection against a high grazing pressure and thus can only be successfully applied in zones where grazing pressure is not the major issue causing riverbank vegetation to decline.
The BESE-elements have already been successfully applied in several riverbank restoration projects in the Netherlands, mainly to counteract the predation pressure. See project photos below.
