Abstract:The Louisiana Department of Transportation and Development (DOTD) was
tasked by the legislature in Senate Resolution 105 to study solutions to the buildup of sediment at Louisiana ports along the Mississippi River and to consult with
the Louisiana Department of Agriculture and Forestry (LDAF) relative to the
issues farmers face in transporting agricultural crops to market. The deposit of
sediment at entrances to Louisiana ports on the Mississippi River hampers access
to the ports and impacts farmers who use the ports to transport diverse crops
to market. Finding solutions to reduce sedimentation and subsequent dredging
costs, or other affiliated issues relevant to mitigating the build-up of sediment, is
vital to the state’s agricultural base. Sedimentation in ports is directly related to
sediment yield from the watershed, river flow, and velocity patterns in the vicinity
of port entrances. Understanding the fundamental drivers of sedimentation and
the governing processes responsible is key to the development of mitigation
strategies, the development of Strategic Plans for dealing with such problems,
and finally with economic projections to implement such solutions.
