The decadal evolution of the dunefoot position along 120 km of the Holland coast is analysed. Firstly, a new definition of dunefoot is introduced based on hydrodynamic and morphologic considerations, which is not affected by local and instantaneous processes occurring immediately before the bathymet

β¦ Synopsis
This paper considers the problem of forecasting coastline position in response to a fluctuating wave climate. Statistical moments are introduced as a method for describing shoreline evolution and variability. Equations are derived and solved for the statistical moments of shoreline position. These equations describe analytically the time-dependent ensemble averaged solution, and its dependence on wave climate without the need for computationally intensive Monte-Carlo simulations. The average is understood to be taken over the ensemble of possible wave sequences. An example application, based on a time series of nearshore synthetic wave conditions, is used to illustrate how the technique might be used in practice to account for both shortand long-term variability in wave climate.

The effect of using time-averaged wave statistics in a simple empirical model for shoreline change is investigated. The model was first calibrated with a six-year time series of hourly wave conditions and weekly shoreline position at the Gold Coast, Australia. The model was then recalibrated with th
