The study area for the coastal geomorphology study is delimited by Steveston Jetty to the north, Point Roberts to the south, the 100 m water depth contour to the west and the top of the bank along the eastern Roberts Bank shoreline (see Figure 6).  Additional field investigations and studies were carried out in Boundary Bay to provide complementary information on tidal channel formation and beach processes.  The limits of many numerical models were extended beyond the study area boundaries to improve the quality of the results.
