The indicated trend is for the magnitude of the inertial forces to increase 

 slowly toward the breaker zone where they reach their maxima. Shoreward of 

 the zone of high breaker energy they decrease again. The extension of high 

 Reynolds numbers in the swash-berm zone is an indication of the effect of 

 previous waves breaking closer inshore at times of higher tidal reaches. 



An important result of this investigation comes in the realization of 

 the significant effect on the dynamic properties of the immersed sands 

 exerted by the high kinematic viscosity of the ocean water at Virginia 

 Beach at the time the study was conducted. This factor's importance was 

 also confirmed in an independent investigation (Harrison and Krumbein, 

 1964) of the relative importance of various environmental parameters on 

 mean size in the shoaling-wave zone at Virginia Beach.
