|
 | 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 ... |

|
| This report, the first of a series, describes the coastal modeling package TWAVE (Typhoon and WAVE) developed under the Surge and Wave Island Modeling Studies (SWIMS) project capable of modeling tropical cyclone winds, waves, storm surge, and coastal inundation. The TWAVE flood and inundation package is a practice-oriented engineering modeling tool. The first version of TWAVE is described in this report and will be updated based on user feedback in ... |

|
| This study provides the Honolulu District (POH) with numerical modeling tools for understanding nearshore circulation and sediment transport for Southeast Oahu (SEO). Circulation and wave models are developed and validated for this region and can be applied to assess sediment transport potential for various forcing conditions and to determine the likelihood of accretional and erosional areas within the model domain. Application of a wave model includes the generation of a ... |

|
| The purpose of this study is to determine if the Savannah Harbor Deep Draft Navigation Project is adversely impacting the shores of Tybee Island (including sand lost from the beach and the Tybee shelf). The study methodology includes numerical modeling of waves, currents, water levels, and sediment transport rates and sediment budgets analysis for pre-project and post- project conditions. Sediment budgets were developed for the period 1854 to 1897 (pre-project) ... |

|
| A curvilinear version of the nearshore circulation model SHORECIRC is developed based on the quasi-3D nearshore circulation equations derived by Putrevu and Svendsen [Eur. J. Mech. 18 (1999) 409 427]. We use a generalized coordinate transformation and re-derive the equations in tensor-invariant forms. The contravariant component technique is used to simplify both the transformed equations and boundary conditions. A high-order finite-difference scheme with a staggered grid in the image domain ... |
