ENDNOTES 



1. G. W. Simmons, personal communication, December 1986. Much of the in- 

 formation in this section was provided by Mr. Simmons, formerly Engineering 

 Technician, Research Division, BEB and CERC, who directly performed many of 

 the movable-bed model tests in the LWT. 



2. Saville (1957), who reported on four cases with the 0.22-mm sand, states 

 that "... the wave heights varied appreciably (about +/- 20 %) with time and 

 with distance along the tank due to reflections off the beach, and the change 

 in this reflection pattern with changes in the beach profile. The heights ... 

 are considered representative averages." The first tests done by Saville 

 included Cases 100 and 110, in which the profile eroded to reach the end wall 

 of the tank, producing notable reflection. 



3. Saville has subsequently stated that most of the variation in wave height 

 was probably produced by changes in the beach profile which changed reflection 

 characteristics of the beach (Saville, personal communication, March 1987).
