Foreshore slope was determined at the same time each sample set was taken. 

 Figure 49 shows the strong positive correlation coefficient (r = 0.88) between 

 the average mean grain size and the average foreshore slope for each of the 15 

 profile lines; Figure 50 shows the decrease in average foreshore slope from 

 north to south.
