Currents generated by 4 ft-4 sec, 270-deg wave at + water level during beachfill test on Plan 3; Presque Isle Lakeview Park Model Study 6. Bottin (1982) conducted a study on Lakeview Park, a recreational facility located in and owned by the city of Lorain, Ohio, along the southern shore of Lake Erie. The project consisted of a segmented detached breakwater with three 76-m-long rubble-mound segments; a 59-m-long rubble-mound extension of the east groin, an increased crest height for the landward 15 m of the pre- project west groin; and initial placement of 84,106 cu m of beachfill. The detached breakwater and groin modifications were designed and installed to protect the beachfill and the preproject shore. After construction a tendency for localized erosion of the beachfill on the eastern side of the west groin was observed. The fill was replenished but again eroded in the same manner to form a stable but narrower than desired beach. An aerial photograph show- ing the typical condition of the beachfill east of the west groin is shown in Figure C7. 7. Movable-bed hydraulic model tests were conducted to qualify the de- gree of erosion at Lakeview Park for various improvement plans. Because of limited funds testing of the proposed modifications for Lakeview Park was con- ducted using a portion of the l:50-scale model of Presque Isle, Pennsylvania. The Lakeview Park structures and immediate underwater contours were installed on a section of the Presque Isle model. A portion of the fixed-bed model was C7.
