The Lower Mississippi River and the Coriolis Forceby Brien R. Winkley,
Document Type: Proceeding Paper
Part of: Hydraulic Engineering
Abstract: Weather patterns and large bodies of water respond to the forces generated by the earth's rotation. A large north-south flowing river, such as the Lower Mississippi River, meandering through an erodible alluvium should develop measurable bendway geometry significantly different in right-hand bends than in left-hand bends. Survey data from the 1911-15 river, prior to stabilization and flood control efforts and the 1973-75 river, surveyed following one of the highest floods of record, were compared. Results of a geometrical analysis of river bends, indicate that the Coriolis force does have a pronounced affect on channel geometry.
