Sediment Flow


Avulsion Sections

MS and Atchafalya carries only 1/2 the sediment used to...significant drowning is evident. 

40% continental US

MS always meandered but levees are preventing river from making next move (silver outlining with blue shading is the general flood zone today).

Dams on MS, Missouri and others have prevented coastal regenerating sediment from counter acting erosion. This loss is scarcely effective to wildlife and the little towns of rich, Acadian culture. As well as the swamps that do much to absorb storms and protect oil industries in NO from storms.

Less Mighty Mississippi

Sediments lessoning through the years. Large reservoirs on Missouri and Arkansas account for biggest loss.
