Abstract | Hydrodynamic conditions in the Oosterschelde have changed as a result of the Delta Project. Engineering works were carried out between 1960 and 1970 in the northern branch of the Oosterschelde. The Grevelingen dam was built in 1964 and the Volkerak dam was completed in the spring of 1969. With the completion of these dams, the northern branch of the Oosterschelde was cut off from other estuaries, and river flow was then regulated by a sluice complex in the Volkerak dam. Between 1980 and 1987 a storm-surge barrier was constructed across the mouth of the Oosterschelde, and two compartmentalisation dams were built in the eastern part of the basin. The storm surge barrier decreased the effective cross-sectional area at the mouth from 80 000 m² to 17900 m² . The compartmentalisation dams reduce the surface area of the Oosterschelde basin from 452 k²2 to 351 km². The hydraulic impact of the works is demonstrated with data from field measurements and data from model calculations. |
