Sediment Diversion

Mid-Breton Sediment Diversion

  • Project TypeSediment Diversion
  • Project BasinBreton-Chandeleur Basin
  • ParishPlaquemines

This project will be located along the east bank of the river, perhaps in the vicinity of White Ditch. This sediment diversion will convey fresh water and sediments into deteriorating marshes that drain into Breton Sound. The brackish marshes in the influence area have disappeared due to a combination of changes in the supply and distribution of fresh water, rapid subsidence, saltwater intrusion, sediment starvation and storm events. This project will reconnect the influence area with the river and divert sediment and fresh water during flood pulses, building new land and sustaining existing marsh.
