Kraijenhoff van de Leur Laboratory for Water and Sediment Dynamics
The experimental research of the Laboratory for Water and Sediment Dynamics mainly focuses on morphological responses to channel flow and overland flow. Current research topics are in the fields of stream restoration, gully erosion, side channels created by longitudinal dams and bedform dynamics.
Facilities
Straight flume
The straight flume has an effective length of 13.6 m and an internal width of 2.6 m. The flume features a sediment catch, which can be connected to the sediment pump for recirculation of sediment.
Tilting flume
The tilting flume is a 1.2 m wide tilting flume, with an effective length of 14.4 m. The flume has sediment catch at the downstream end, and a sediment pump for recirculation of bed material.
Rainfall simulator
To test the impact of a raindrop on a soil surface and test the vulnerability of a soil type to overland flow and erosion, a rainfall simulator has been installed.
