Figure 9. Volume of material dredged for maintenance from the MSC (1965-1994) 



Figures 10 and 1 1 show the cumulative volumes dredged for maintenance in the 

 GIWW and MSC, respectively. The closest section of the GIWW to the intersection 

 (sta 612-1-000 - 616-1-000) is the one exhibiting most rapid shoaling over the years. 

 Instead of being uniform or a linear function of time, the cumulative volume of this 

 stretch increases at a greater rate. The best-fit power function to this curve is:
