83. Bowen (1980) investigated bar formation by standing waves and 

 presented analytical solutions for standing waves on plane sloping beaches. 

 He also derived equilibrium slopes for beach profiles based on Bagnold's 

 (1963) transport equations and assuming simple flow variations. 



84. Dally (1980) and Dally and Dean (1984) developed a niamerlcal model 

 of profile change based on the assumption that suspended transport is dominant 

 in the surf zone. The broken wave height distribution across -shore determined 

 by the numerical model supplied the driving mechanism for profile change. An 

 exponential -shaped profile was assumed for the sediment concentration through 

 the water column. 



85. Davldson-Arnott and Pember (1980) compared bar systems at two 

 locations in southern Georgian Bay, the Great Lakes, and found them to be very 

 similar despite large differences in fetch length. The similarity was 

 attributed to the same type of breaking conditions prevailing, with spilling 

 breakers occurring at multiple break points giving rise to multiple bar 

 formations (Hands 1976). 



86. Hashimoto and Uda (1980) related beach profile eigenvectors for a 

 specific beach to shoreline position. Once the shoreline movement could be 

 predicted, the eigenvectors were given from empirical equations and the three- 

 dimensional response obtained. 



87. Shibayama and Horikawa (1980a, 1980b) proposed sediment transport 

 equations for bed load and suspended load based on the Shields parameter 

 (Madsen and Grant 1977). A numerical beach profile model was applied using 

 these equations which worked well in the offshore region but failed to 

 describe profile change in the surf zone. 



88. Davldson-Arnott (1981) developed a numerical model to simulate 

 multiple longshore bar formation. The model was based on the mechanism 

 proposed by Greenwood and Mlttler (1979) for bar genesis, and the model 

 qualitatively produced offshore bar movement; but no comparison with measure- 

 ments was made . 



89. Bailard and Inman (1981) and Bailard (1982) used Bagnold's (1963) 

 sediment transport relationships to develop a model for transport over a plane 

 sloping beach. They determined the influence in the model of the longshore 

 current on the equilibrium profile slope. The beach profile was flattened in
