“…The simulation with the model describes only the dynamics of the bypass bar and does not reflect other changes in the coastal profile. Figure 19 shows the surveyed conditions after the storm together with the result obtained from Grunnet et al (2009) and that obtained with the present model concept. The head of the bar is initially located at the 100 m mark on the rs-coordinate system shown in the figure.…”

“…A simulation of the morphological development of a bar that bypasses the harbour Hvide Sande at the Danish Noth Sea coast is performed in order to determine whether the streamline approach described previously gives reasonable results. This particular problem has been examined by Grunnet et al (2009) in a study to investigate a revised harbour layout with improved conditions for bypass of sediment. In the original work of Grunnet et al (2009) the 2DH/Q3D model was validated against field measurements from several storm events.…”

In the original work of Grunnet et al (2009) the 2DH/Q3D model was validated against field measurements from several storm events. One of these events is selected, where a single bar bypassed Hvide Sande harbour during 5 days in 2003.…”

A morphological modelling concept for long term nearshore morphology is proposed and examples of its application are presented and discussed. The model concept combines parameterised representations of the cross-shore morphology, with a 2DH area model for waves, currents and sediment transport in the surf zone. Two parameterization schemes are tested for two different morphological phenomena: 1) Shoreline changes due to the presence of coastal structures and 2) alongshore migration of a nearshore nourishment and a bar by-passing a harbour. In the case of the shoreline evolution calculations, a concept often used in one-line modelling of cross-shore shifting of an otherwise constant shape cross-shore profile is applied for the case of a groyne and a detached breakwater. In the case of alongshore bar/nourishment migration an alternative parameterization is adopted. All examples are presented, analysed and discussed with respect to the question of realistic representation, time scale and general applicability of the model concept.
