オランダにおける水害の研究*

Abstract

The Netherlands are mostly influenced by storm surges and the occurrence of these surge waves havepromoted hydraulic research. Especially, the 1953 storm surge resulted in the decision to close off a num-ber of tidal branches in the South-West of the Netherlands: the DELTAPLAN. The least and most diffi-cult closure of the Oosterschelde in the Deltaplan is presented in this lecture, and a large number ofresearch subjects for the design of the storm surge barrier are explained: design philosophy, boundaryconditions, discharge capacity, foundation, wave loads, gate vibrations, sill stability, local scour, bed protec-tion, sedimentation and operations during construction.
