Idealized Marsh Simulations: Sensitivity of Hurricane Surge Elevation and Wave Height to Marsh Continuity

The purpose of this CHETN is to assess changes in peak surge elevation and wave height with changes in the continuity (degree of segmentation) of an idealized marsh-like coastal feature.

Description
Summary:The purpose of this CHETN is to assess changes in peak surge elevation and wave height with changes in the continuity (degree of segmentation) of an idealized marsh-like coastal feature. Application of varying elevation and bottom friction in model simulations is used to represent a non-continuous marsh delineated by channels. The analysis isolates the sensitivity of the modeled storm surge to changes in the continuity of an idealized marsh, and qualitatively indicates the degree to which a segmented marsh may influence the storm surge protection compared to a fully continuous marsh. This is the fourth in a series of technical notes on the influence of marshes on storm surge and waves.
