Incident Waves

In order to investigate the response of beach profiles to incident waves, computations by the empirical eigenfunction analysis proposed by Winant et al. are performed. The analysis of the data obtained at Ajigaura Beach over three years from 1976 to 1979 indicates that beach profile changes due to longshore and onshore-offshore sediment transport are separable by the empirical eigenfunction method. The beach profile changes due to longshore sediment transport has a time lag of 12 weeks with respect to the change of wave direction at Ajigaura Beach. It was found theoretically that this time lag was due to the sand waves propagating in the longshore direction. Regarding as onshore-offshore sand transport, the second eigenfunction is associated with the beach changes due to onshore-offshore sand transport caused by the change of wave height.

Further Development

An interesting question arising within the scope of the further development of the German tidal rivers Elbe and Weser, is whether tidal dunes or sand waves will be formed after the navigation channel deepenings and that the success of the development measures will thus be partially or fully undone. In order to be able to better assess the formation and regeneration of these large patterns after dredging, heightened knowledge of the sand transport in a tidal dune field is necessary. A possibility of investigating the sand transport in a tidal river with pronounced tidal dunes in the field, can be realized by measurings with luminaries or tracers. The advantage of investigations in the field is, that all laboratory required scale effects are eliminated. The more difficult measuring comprehension of the course of the test in prototype must be solved through purposefully planned investigation programs. Subsequent to observations of many years standing, on behavior of four tidal dune areas in the navigation channel of the Weser River estuary (6), investigations were carried out with luminaries above reach 1 (Fig. 1) from September till November 1974. The aim was, to obtain information on the transport mechanism for tidal dunes and heightened knowledge on the causes of regeneration after dredging.
