13. ABSTRACT (Maximum 200 words) 



A l:100-scale (undistorted) three-dimensional hydraulic model was used to investigate the effects of 

 proposed modifications at Camp Ellis Beach, Saco Bay, ME, with regard to shoreline erosion at the site. The 

 model reproduced about 2,438 m (8,000 ft) of the Maine shoreline. Camp Ellis Beach, the Saco River entrance, 

 and sufficient offshore area in the Atlantic Ocean to permit generation of the required test waves. Proposed 

 improvements consisted of roughening a portion of the existing Saco River north breakwater; installation of a 

 sandfill, offshore berms, and spur jetties; and the removal of the existing north breakwater. Historical tests also 

 were performed to aid in understanding formative processes at the site. A 24.4-m (80-ft-long) unidirectional, 

 spectral wave generator, an automated data acquisition and control system, and a crushed coal tracer material 

 were used in model operation. Test results led to the following conclusions: 



a. During periods of storm wave activity and high tide conditions (+2.7 m (+8.8 ft)) at Camp Ellis Beach, 

 wave heights ranging from 2.4 to 2.7 m (8 to 9 ft) will occur adjacent to the beach for existing conditions. For 

 extreme storm events with tides in excess of +4.0 m (+13 ft), wave heights adjacent to the beach will reach 

 approximately 3.4 m (11 ft). Little wave energy appears to reach the area, however, for low tide conditions 

 (0.0 m or ft).
