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
