| Abstract |
This paper reviews practices and trends in hydrodynamic and statistical analyses and modelling in the Netherlands with regard to the risk of coastal flooding. We restrict ourselves to the physical phenomena of tides, storm surges and wind waves. We first give a brief outline of established policy in the Netherlands regarding accepted levels of risk of flooding, and current changes therein. This is followed by a summary of a statistical reanalysis of historical storm–surge data combined with numerical hydrodynamic modelling, aimed at improved estimates of probabilities of occurrence of extreme water levels along the Dutch coast. Recent developments concerning the physical and numerical modelling of inundation of low–lying areas are presented. State–of–the–art modelling of wind waves in coastal areas is also reviewed. Research issues in the area of coastal modelling for flood defence are indicated. |
