Numerical simulation using the contour line change model was carried out to restore the sandy beach on the lakeshore in Ukishima area in Lake Kasumigaura. Past aerial photographs were compared to investigate the long-term shoreline changes of the Wadamisaki sand spit formed in the southeast part of the lake. The predominant wave direction of wind waves was determined from the shoreline changes in Ukishima area. Given the wave height predicted using the SMB method and predominant wave direction, the optimum arrangement of groins was determined using the contour line change model considering the effect of grain size changes.
