Titre : Bird’s Foot Delta, Mississippi River, Louisiana, U.S.A. March 1994
Description : (La description de cette image n'existe qu'en anglais)
A constant supply of sediment ensures the dramatic growth into the Gulf of Mexico of the Mississippi River bird’s foot delta. To ensure that the river is navigable by large, oceangoing vessels, jetties have been built on the westward-projecting main channel through the delta, whose shape changes daily. Because of heavy silting throughout the delta, constant dredging is required to keep the main channel open for ships traveling to New Orleans and beyond. The distance from the southern tip of the delta to the Port of New Orleans is 90 miles (144 kilometers).
