Abstract:

The purpose of this CHETN is to examine storm surge and wave reduction benefits of marsh restoration, as well as the impact of future wetland degradation on local surge and wave conditions. Storm surge simulations of representative moderate and severe hurricanes were performed using the ADCIRC storm surge model, with the inclusion of radiation stress gradients from the STWAVE nearshore wave model. Coupled model simulations were made for wetland landscape configurations in south Louisiana that involved hypothetical restored and degraded wetland features. This is the first in a series of tech notes on the influence of marshes on storm surge and waves.
