Purpose
|
Berm: The goal of this study is to assemble a baseline value of the
sediment properties of the dynamic Chandeleur Island E4 Berm in order to track
movement temporally, and to contribute to current and future modeling efforts.
Marsh: Overall Goal 1) Evaluate if the berm or original barrier island sediment
(primarily sand) are being sequestered in back-barrier environments (marshes
and flats) or bypassing the system 2) Evaluate whether the berm emplacement
influenced sedimentation in the back-barrier environments Specific Objectives
and Tasks 1) Quantify recent (<100 yr) mass accumulation rates in back-barrier
environments along the Chandeluer Islands and the dominant form of
sedimentation (inorganic versus organic) 2) Monitor short-term mass
accumulation rates (analyzed through the duration of the project) following
the berm emplacement and its infusion to the main-barrier island
3) Compare short- and long-term rates to evaluate changes in the mechanism and
source of sedimentation in the back-barrier environments
