The Influence of Retention Basins on Tidal Dynamics in Estuaries

The Ems estuary suffers from high concentrations of suspended sediment, which is harmful for the life in the river. Sediment import occurs because of tidal asymmetry, a difference between the velocity of the current during high tide and low tide. The use of retention basins are a possible measure to reduce the tidal asymmetry. An analytic model,...

Retention of Rhine water in the Rijnstrangen to mitigate drought

Over the last years the Netherlands has often had to deal with droughts and water shortages during summer. This problem is caused by long periods without rain but with high evaporation rates and is enhanced by groundwater extraction for drinking water. Due to climate change, these droughts are expected to occur more often and become more severe....

Hydrograph shape variability on the river Meuse

Design water levels are a basic concept in flood risk management practice. These water levels with a specified return period are used for the design of dikes and other flood protection measures along the river Meuse. Current practice is that these water levels are determined by hydrodynamic simulation of a standard design hydrograph at the...

Retentiebekken Lateraalkanaal west: Bescherming tegen hoogwater?

Na het hoge water in de Maas in 1993 en 1995 is projectorganisatie De Maaswerken opgericht. Deze heeft onder meer als doel gesteld om de bewoonde gebieden langs de onbedijkte Maas te beschermen tegen hoogwater tot een niveau dat gemiddeld 1/250 keer per jaar optreedt. Een van de geplande maatregelen om dit doel te bereiken is de aanleg van...
