EFFECTS OF COASTAL LANDFORM CHANGES ON STORM SURGE ALONG THE HATTERAS ISLAND BREACH AREA

Abstract


Storm surge is known to be the source of many coastal problems including dune erosion, overwash deposits and inlet breaching. The work discussed in this paper arises out of an effort to develop geospatial tools and workflows that integrate with process based numerical models in order to improve the understanding of the importance of landform and complex landform changes in these processes building on the use of existing models. The effects of landform changes on calculation of storm surge characteristics (elevation and velocity) are investigated for three different cases created using the geospatial workflows coupled with ADCIRC modeling efforts.
