Figure 32. Graph showing different relationships between distance from a jetty and beach slope for shorelines adjacent to the Saco and Scarborough Rivers. The relationships are clearly best represented by exponential, not linear, expressions. It is interesting that the updrift (accreting) shorelines, e.g., S of Saco River (blue) and W of Scarborough River (red), are not similar in slope, as one may expect. However, data for E of the Scarborough River (green) and S of the Saco River (blue) are very similar. This may relate to the fact that both regions 1 and 4 act as individual littoral cells.
