Figure 39 . Evolution of peak offshore net sand transport rate 

 for 16 CE cases 



peak offshore transport rate was usually small or sometimes even zero through 

 most of the run (see Figure 35). 



326. Various trial empirical expressions to describe time decay of the 

 peak offshore transport rate were least-squares fitted for cases having strong 

 offshore transport in the combined CE and CRIEPI data set (12 cases). The 

 best general agreement was obtained with an inverse dependence of the maximum 

 transport rate on time according to 



q^o 



%> = 



1 + at 



(20) 



where 



q„ = peak transport rate 

 q^Q = peak transport rate at time t = 

 a = rate coefficient of decay of peak transport rate
