assignment/short description
Radial gates of sluice in Haringvliet Lifting gates of weir Lith in river Meuse
In 2008 Deltares was commissioned to check the dynamic behaviour of the control gates of a couple of large hydraulic structures in the Netherlands in various flow situations. This check was neceassary because the operational and hydraulic conditions had been changed. To that aim insitu measurements were executed and a desk study undertaken.
The first object concerned a sluice complex in the south-western delta area, located in the former sea arm Haringvliet. This sluice complex with a total lenght of 1050m has seventeen flow openings, each of them controled by a set of two 56.5m span radial gates. The sluice complex is used to discharge surplus water from the south-western area to the North Sea. Rivers Meuse and Rhine contribute to this surplus water.
The second object was the weir in the River Meuse at Lith. This weir is the last one in a series of seven weirs in the River Meuse within the Netherlands territory and is used to control the water level of the river, in particular with the purpose of providing sufficient water depth for navigation. On the basis of the measurements, directions were given for a safe operation of the gates of both structures under the future hydraulic and operational conditions.
