Pilot project Lippenbroek is a flood control area (FCA) with a controlled reduced tide (CRT). This paper presents results from ongoing multidisciplinary hydromorphological research on the experimental site. Characteristics, distribution and composition of the sediments are of primary importance to understand the hydrodynamic and the physical, biological, geochemical processes of the system. The characteristics of sediment natural compositions were examined and compared to those in the main channel of the Schelde. Combining water flows and sediment fluxes measured at the entrance and exit sluices allow estimating the sediment entrapment within the CRT-area. Volumes of sediment which retain within Lippenbroek can be converted into sedimentation height using in-situ measured sediment densities. In addition, the spatial distribution of the sedimentation is monitored on multiple sedimentation plots, which in turn allow estimating the rate of sedimentation. Relationships between inundation characteristics and sedimentation rates are investigated.
