Abstract

In a slender water body with a large aspect ratio, the angle of wind waves relative to the direction normal to the shoreline may exceed 45°, resulting in the emergence of cuspate forelands and the segmentation of a lake, because the fetch distance along the principal axis becomes large. The BG model was used to predict the segmentation of a rectangular water body by wind waves when the probability of occurrence of wind direction is given by a circular or elliptic distribution. The changes in wave field and sand transport flux over time were calculated to investigate the wave-sheltering effect of the cuspate forelands. A rectangular lake segmented into circular or elliptic lake, when the probability of occurrence of wind direction is given by a circular or elliptic distribution, respectively.
