Summary 
Waves at Monmouth Beach typically approach from 90 to 157.5 deg, with a 
dominant direction of 135 deg. Less than 2 percent of the waves approach from 
north of east. These waves are fetch limited and have small heights (>1.6 ft 
(0.5 m)) and short periods (>5 sec). The dominant southeast and east wave 
directions shown in the wave statistics and the storm data indicate that wave 
focusing by Shrewsbury Rocks would impact the mid to north end of 
Contract 1A and not be a factor in the hot spot located at the south end of the 
project. Wave focusing would be manifest as a local amplification in wave 
height and local reversal or gradient in wave direction. The northeasterly angle 
of the bathymetry contours between the hot spot and Shrewsbury Rocks could 
increase the breaking wave angles on the northern portion of the hot spot and 
contribute to a local increase in northerly sand transport.
