Geological background and geomorphology of the Boundary Bay intertidal zone, British Columbia / P.R. Hill. : M44-2024/2E-PDF

"This paper presents geological and geomorphological background information on Boundary Bay, an intertidal shoreline located near Delta and Surrey, British Columbia, based on recently collected Lidar data. The tidal flats overlie older deposits of the Fraser River delta and, locally, Quaternary deposits. A previously collected radiocarbon age suggests that the delta has been under transgression for approximately 4000 years. The modern shoreline has been extensively dyked for land reclamation and flood protection since the late 19th century. Narrow extents of saltmarsh are present seaward of the dykes. The High Intertidal Zone, is strongly wave-influenced as evidenced by abundant shore-parallel bars, whereas the Intermediate Intertidal Zone is tide-dominated being characterized by incised tidal channels and eelgrass-stabilized interchannel areas"--Abstract, page 1.
