A spur jetty may also be included as part of a beach nourishment plan to aid in maintaining the
sediments in the beach area (Walther and Dombrowski 1999). A spur could be placed on a
downdrift jetty as well as on the more typical updrift jetty if it was thought that the nourished
downdrift beach might have a tendency to locally feed back along the downcoast jetty towards
the navigation channel.
