Morphodynamics of the Erosional Phase of Crevasse-Splay Evolution and Implications for Diversions

Researchers used the West Bay diversion in lower Plaquemines Parish as analogue for state-proposed sediment diversions in Lower Barataria and Lower Breton basins. Although the state has since decided to move forward with sediment diversions in the upper part of the river first, measurements in West Bay outfall area could help validate Delft3D modeling being done to estimate the land-building ability of these sediment diversions. This paper specifically looks at the erosional phase of this delta evolution formed by a crevasse.
