Abstract
A number of coastal engineering and ecological considerations are given, concerning the changes from Grevelingen estuary into saline Lake Grevelingen. New hydraulic methods were used to close the 5–7 km wide estuary at both ends. The eastern secondary dam was closed in 1964 by a combination of tight caissons and rubble-stone from a cable-way. The closure gaps in the western primary dam were closed simultaneously in 1971 by sluice caissons and large concrete blocks dumped from a cable-way. The main objects of damming up Grevelingen estuary were to shorten and to strengthen the total length of the coast and the sea-walls, and to improve the fresh-water economy of the area. In the course of time additional motives have been added. Lake Grevelingen evolved into a relatively stable and diversified saline ecosystem. The considerable values of water quality and ecology of the present lake have to be weighed against the bad quality of fresh Rhine-water and concomitant biotic communities.
