한국어 초록
An algorithm to allow shoreline movement during numerical experiment on sediment transport, deposition or resuspension forgeneral coastal morphology is proposed here. The bed slope near shoreline, i.e. mean sea level, is influenced by bed
material, tidal current, waves, and wave-induced current, but has been reported to remain within a stable range. Its annual
variation is not large, either. The algorithm is adjusting the bathymetry, if the largest bed slope within shoreline band
exceeds a given bed slope due to continuous erosion at zones below the shoreline. This algorithm automatically describes
retreat of shoreline caused by erosion, when used within a numerical system. The algorithm was tested to a situation which
includes a continuous dredging at a point, and showed satisfactory development of concentric circle contours. Next, the
algorithm was tested to another situation which includes sinking of eroded part of bed plate, and produced satisfactory
results, too. Finally, the algorithm was tested to a movable-bed laboratory experimental conditions. The shoreline movement
behind detached breakwater was reasonably reproduced with this algorithm.
