“…The STFATE (Johnson 1990) simulates the areal distribution of dredged material in open water after it has passed through the water column on an individual release of the barge load. The CMS Lin et al 2008Lin et al , 2011Lin and Demirbilek 2010) calculates wave transformation and wave-induced currents, water level change by tide, wind, and waves, interacting waves and currents, and sediment transport and morphology change. The CMS implicit flow model is used in this study to calculate both short-and intermediate-term changes to the dredged material placement site.…”

The US Army Engineer District, San Francisco (SPN) and the Coastal Inlets Research Program conducted a pilot study to consider various placement locations for dredged material in vicinity of Noyo Harbor, CA. Approximately 30,000-40,000 cu yd/yr of beach-quality sediment is dredged from the navigation channel and the lower Noyo River, located on the north central California coast. The pilot study investigated several potential locations for placement of dredged sediments in one of two areas north of Noyo Bay. The investigation included field data collection and numerical modeling of near-field sediment transport and suspended sediment concentration during and after placement of the dredged sediments under combined wave and current conditions. The numerical model provided the technical information necessary for SPN and Noyo Harbor stakeholders to evaluate a location site that is economically feasible for the optimum sediment placement. Upon acceptance by the stakeholders and receipt of additional funds, a demonstration project will be conducted, and the Dredged Material Management Plan (DMMP) for Noyo Harbor will be updated to include a beneficial use site for nearshore placement.

“…CMS-Wave is a 2-D spectral wave transformation model that solves the steady-state wave-action balance equation on a nonuniform Cartesian grid (Lin et al 2009. The model is designed to simulate wave processes that are significant in coastal inlets, in the nearshore zone, in the vicinity of jetties and breakwaters, and in ports and harbors.…”

“…The calculation of the wave transmission coefficient in the CMS is based on d' Angremond et al (1996) and the method can be applied to both monochromatic and random waves (Lin et al 2009). The wave transmission coefficient for permeable breakwaters is a function of the crest width, the crest freeboard, the significant wave height, the fore-slope, the incident wave steepness, and the structure porosity.…”

Dana Point Harbor is located on the southern California coast, midway between Los Angeles and San Diego. The harbor is protected by dual semi-permeable breakwaters, the East and the West Breakwaters. The permeability of the breakwaters has been designed to promote circulation and improve water quality in the harbor. However, wave and flow actions have increased sediment movement around the West Breakwater and resulted in harbor channel infilling in recent years. To investigate the sediment transport around the porous breakwater and reduce potential dredging cost in the future, an integrated coastal wave, hydrodynamic and sediment transport numerical model was used to investigate the effect of the permeability of breakwater. First, the model was validated with the field measurements of waves, current, and water surface elevation at two ADCP gages located on the harbor side and the ocean side of the West Breakwater. Further validation in the model's capability to simulate wave flow through a porous structure was also performed with a laboratory experiment of low-crested structures under regular waves. Wave transmission, flow and sediment around the West Breakwater were calculated for 1-year period of [2009][2010]

“…The use of the CMS in wave modeling is more realistic for bay applications and more accurate than classical fetch-based empirical curves as the wind wave generation and growth are strongly affected by the complex of bay geometry and varying bathymetry [15,16]. This is particularly true in the Chesapeake Bay because many river tributaries, navigation channels, shoals, islands, and peninsulas coexist in the Bay.…”

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.
