each cell face. The sum of the two discharges (wave-induced and tidal) 

 constituted the total water discharge. 



112. The dimensionless sediment concentration for the surf zone and be- 

 yond the surf zone was calculated from equations described earlier. In the 

 numerical model, the sediment concentration was defined at the center of a 

 cell. The water discharge was then multiplied with the sediment concentration 

 to obtain sediment discharge on a cell face. 



113. For a given tidal and wave-induced flow condition the continuity 

 equation (Equation 97) was solved to determine the change in the bed elevation 

 Ah of a cell. A time-step At of 1 hr was used for the sediment transport 

 model. A sensitivity analysis on time-step (At = 10, 30, and 60 min) showed
