Design of coastal structures, harbour facilities and shipyards
1975 - 1976 Earthmoving, harbour and railroad construction ( Al Khobar, Saudi Arabia )
1976 - 1982 Design of the Storm Surge Barrier Oosterschelde. The Barrier is the last part of the Delta Plan protecting Holland against storm surges on the North Sea
  • Probabilistic approach of hydraulic loading
  • Risk analysis of the total system of the Barrier and probabilistic design calculations
  • Hydraulic model tests on elements of the Barrier consisting of large rocks (sill, bottomprotection)
