Abstract: In the southwest of the Netherlands a storm surge barrier is to be built in the waterway that gives access to the port of Rotterdam. Strict design conditions ensure that only very slight hindrance to shipping will occur. Combined with dikes along the rivers, the barrier will provide the required safety at lower costs and in a shorter period of time than was envisioned in the original scheme, derived from the Delta Plan. The purpose of the barrier design is reducing design water levels for the river dikes. Reliability aspects are integrated into the computation of design water levels.
