Tidal scour

[2][better source needed][3][4] Two locations in the United States where tidal scour is the predominant shaping force is the San Francisco Bay and the Elkhorn Slough.

[2][better source needed] The slough was directly exposed to tidal flux beginning in 1947 with the creation of the Moss Landing Harbor.

[2][better source needed][5] Multiple studies have been done on the slough since tidal exposure to catalog the morphological change and determine how long it will take for the system to reach equilibrium.

[2][better source needed] Tidal scour is most apparent when a barrier is breached due to natural or anthropogenic forcing.

[5] With direct influence from the Ocean, slough morphology can change significantly making it difficult for native species to persist.

Elkhorn Slough is the focus of many tidal scour studies. Tidal scour became prevalent with the creation of the Moss Landing Harbor seen toward the bottom of the image.
