6: Policies & Programs
dredging costs by removing sediment from the channel and build up the wetlands that protect navigation routes from storm surge damages. As we learn more about how to design and build sediment diversions through master plan funded activities and the Mississippi River Hydrodynamic and Delta Management Study (see Chapter 6), we can identify how best to customize our use of restoration options.
5: 2012 Coastal Master Plan
Sediment diversions depicted in the map above would be operated in coordination with high river events and seasonal flows. Operation at maximum capacity would occur only at targeted intervals for a fraction of time each year.
