HYDRAULIC BOUNDARY CONDITIONS FOR A MAJOR DISCHARGE FACILITY — THE IJSSELMEER PROJECT, THE NETHERLANDS

摘要

The IJsselmeer (lake IJssel) in the Netherlands is a man-made lake that was formed when a 1200 km~2 portion of the Wadden Sea was closed of in the 1930's. Today, the lake is vital to the water management of a major portion of the Netherlands. In view of expected climate change a major increase of the discharge capacity in the dam is currently under preparation. An extensive study was undertaken to establish hydraulic conditions for structural design. This paper describes the model that was created to establish relevant combinations of head difference and wave loads at the structure.
