The Ministry of Water infrastructure (Rijkswaterstaat) started the longitudinal dams pilot as an innovative alternative to the typical river groynes in the Waal river. Along 10 kilometer stretch, the longitudinal dams create a side channel parallel to the main river to improve the hydraulic, ecological and recreational conditions for the river. Since 2014, the WaalSamen group measure and compare the effects before, during and after the construction of the longitudinal dam to adapt ther design and maintenance as necessary. The WaalSamen group includes representatives from Rijkswaterstaat, the inland shipping sector, national and regional angler associations and some of the Dutch Universities, research institutes and consultancies that are part of the RiverCare program.
