Abstract
Recent ecological studies (Collas et al., 2018) show that ship-induced waves can reduce suitability of fish habitats along the river banks between groynes. Specifically eggs and young fish are vulnerable to these waves (Wolter &
Arlinghaus, 2003). For the river Waal in the Netherlands the breeding and growing season of this fauna is from April to September, which generally corresponds to flow conditions where the groynes in the river are not completely
submerged. The preferred habitat of fish is in the shallow zones close to the bank, which experience a high degree of hydrodynamic variability due to ship-induced waves. The goal of this research is to explore whether fish habitat during the growing and breeding season can be improved by reducing the flow impact of passing ships through structural modifications (“notching”) of groynes.
