Scale model of a training dam using lightweight granulates

Longitudinal training dams (LTDs) are a promising alternative for river groynes. Here we summarize findings of a recent study focused on the along river transition from a series of river groynes to an LTD, where the flow divides between the fairway and the side channel between the LTD and the river bank. A scale model is setup using...

Tidal controls on river delta morphology

River delta degradation has been caused by extraction of natural resources, sediment retention by reservoirs, and sea-level rise. Despite global concerns about these issues, human activity in the world’s largest deltas intensifies. Harbour development, construction of flood defences, sand mining and land reclamation emerge as key contemporary...

Hydraulisch functioneren vispasseerbare cascades

Her en der worden in Nederland in beken en kleine rivieren vispasseerbare kunstwerken aangelegd om vismigratie mogelijk te maken en de ecologie van het systeem te verbeteren. Een veel voorkomende vispassage is de zogenaamde vispasseerbare stortsteen-bekkenpassage, ook wel cascade vistrap genoemd. Cascade vistrappen kunnen een opstuwende werking...
