Again, the model simulated sediment concentrations at all stations agree 

 well with the ship survey data. Due to the relatively mild wind from the 

 southeast, concentration levels during this period are generally smaller than 

 those during 9/01/80 to 9/10/80. Transport of sediments is also weaker due to 

 the smaller wind-driven currents in this period. 



7.7 Summary 



We have performed model simulations on the relative importance of tidal 

 currents, wind-driven currents, and wave in causing sediment movement within a 

 coastal environment. With the limited amount of data, we were able to perform 

 realistic simulations of sediment movement within the Mississippi Sound and 

 achieved reasonable agreement with data. During the study periods, 

 significant deposition, entrainment, and transport of sediments were found 

 within the Mississippi Sound. Future studies should concentrate on simulation 

 of sediment movement during the sporadic high-energy events which have primary 

 influences on the total sediment budget within the Sound. Remote sensing data 

 on suspended sediment concentration can provide synoptic information over a 

 large coastal area, hence could be used to provide better data for model 

 initiation and verification.
