Abstract:The protection of a boat canal at the western entrance of Tangier Island, Virginia, located in the lower Chesapeake Bay, is investigated using different structural alternatives. The existing entrance channel is oriented 45 deg with respect to the local shoreline, and exposed directly to the lower Bay without any protection. The adjacent shoreline has experienced progressive erosion in recent decades by flooding due to severe storms and waves. To protect the western entrance of the channel and shoreline, five different jetty and spur combinations were proposed to reduce wave energy in the lee of jetties. Environmental forces affecting the proposed jettied inlet system are quantified using the Coastal Modeling System, consisting of a spectral wave model and a depth-averaged circulation model with sediment transport calculations. Numerical simulations were conducted for design wave conditions and a 50-year return period tropical storm at the project site. Model results show a low crested jetty of 170-m length connecting to the north shore at a 45-deg angle, and a short south spur of 25-m long, provide adequate wave-reduction benefits among the five proposed alternatives. The model simulation indicates this alternative has the minimum impact on sedimentation around the structured inlet and boat canal.

“…Because there were no current or wave measurements in Corpus Christi Bay, the CMS model calibration with current and wave data was based on a previous study of the neighboring Matagorda Bay for 1 January through 28 February 2014(Rosati et al 2011;Lambert et al 2013). For sediment transport, the model applied the same method used and documented in three previous modeling studies(Lambert et al 2013;Lin and Reed 2015; Wood et al 2017).…”

The purposes of this U.S. Army Corps of Engineers (USACE) Regional Sediment Management Technical Note (RSM-TN) are to document the development of alternative approaches to managing sediment at the intersection of the Gulf Intracoastal Waterway (GIWW) and the Corpus Christi Ship Channel (CCSC), Texas, and to determine the relative benefits and risks of each alternative. These alternatives potentially enhance navigation at this specific location but also enhance general understanding of navigable channel interactions in similar circumstances. The purpose of this study was to provide potential alternatives to managing the sediment at these locations. Sediment budget is discussed for readers to understand the magnitude of the channel shoaling situation in Corpus Christi Bay. The study area is shown in Figure 1.
