context_page_description: The Coastal Wetlands Planning, Protection and Restoration Act was passed by Congress in 1990 to fund wetland enhancement. In cooperation with multiple government agencies, CWPPRA is moving forward to restore the lost wetlands of the Gulf Coast as well as protecting the wetlands from future deterioration. The scope of the mission is not simply for the restoration of Louisiana's Wetlands, but also the research and implementation of preventative measures for wetlands preservation.
  CWPPRA is a partnership between the U.S. Army Corps of Engineers, the NOAA- National Marine Fisheries Service, the U.S. Fish and Wildlife Service, USDA Natural Resources Conservation Services, the Environmental Protection Agency, and the State of Louisiana.
context_section_description: Water and Sediment Diversion – Diversions allow fresh water from the Mississippi or Atchafalaya rivers to be re-introduced through wetland areas.  The flows provide the wetlands with a new source of sediment and nutrients and combat saltwater intrusion.
  Outfall Management – Employed in conjunction with diversion projects, outfall management regulates water levels and flows, increasing the dispersion and retention time of fresh water, nutrients and sediment.
  Hydrologic Restoration – This type of project reverts human-altered and troublesome drainage patterns toward more natural drainage patterns.
  Shoreline Protection – Shoreline protection projects are designed to reduce or halt shoreline erosion.
  Barrier Island Restoration – Designed to protect and restore barrier islands, this project type employs a variety of techniques, such as depositing dredged material to increase an island's size, placing rock breakwaters to reduce wave erosion, and placing sand-trapping fences and vegetative plantings to build and stabilize beaches and dunes.
  Dredged Material Marsh Creation – Projects of this nature utilize dredged material, placing it in deteriorated wetlands or open water so that marsh plants will grow and form new marsh.
  Sediment and Nutrient Trapping – Sediment and nutrient trapping is achieved by constructing or placing structures designed to slow water flow and promote the buildup of sediment.
  Vegetative Planting – Used both separately and in conjunction with other project types, various kinds of marsh vegetation are planted to hold sediment together and stabilize soil.
  Many restoration projects employ two or more restoration techniques.
