Longshore currents in the Gulf of Mexico tend to move from east to west 

 at rates of 1 to 3 mph and tend to deflect outgoing tides to the west. On 

 incoming tides these currents increase to 3 to 6 mph (Chermock 1974). 

 Man-made factors such as ship channels, spoil lands, and causeways tend to 

 alter natural current patterns.
