A restoration plan recovering sandy beaches at Tennozaki in Lake Kasumigaura was investigated. Past lakeshore changes were first investigated through the comparison of old map and aerial photographs. A stable shoreline of a pocket beach was predicted by applying a modified Hsu model (Serizawa et al., 1996). Numerical simulation using a contour-line-change model considering the change in grain size proposed by Kumada et al. (2003) was also carried out. Three-dimensional beach changes when beach nourishment was carried out were predicted by this model.
