 | This Coastal and Hydraulics Engineering Technical Note (CHETN) describes a methodology for representing nonerodible substrates in a two-dimensional (2-D) coastal morphology change models, with emphasis on coastal inlets. The calculation procedure is described, followed by examples showing the functioning of the method. |

|
| Bypassing at inlets can occur across the ebb shoal, through tidal exchange, and by episodic collapse of shoals. To examine ebb-shoal and tidal exchange bypassing in a systematic way, we investigated sediment pathways at an idealized inlet with a coupled tide, wave, and sediment transport-morphology change numerical modeling system. The idealized inlet, ebb shoal, and channel were devised to test the coupled modeling system and isolate sediment transport pathways driven ... |

|
| The interaction of waves and currents at an inlet entrance can be significant. Traditionally, numerical modelers have separated the processes of tidal circulation and wave transformation, but the surf zone and inlet are areas where the interactions are strong and should be numerically simulated to capture the resulting hydrodynamics. This paper describes performance of coupled wave and circulation models for both an idealized inlet setting and an application for Grays ... |

|
| Review of the literature of barrier island and barrier spit breaching reveals there is a paucity of information on the physical processes beyond qualitative reporting of case studies, despite the significant potential environmental and societal consequences that unintended breaches can bring. A breach susceptibility index is introduced to classify breaching potential by storm surge or equivalent inundation mechanism. A recent breach of the barrier spit enclosing Stone Lagoon, located on ... |

|
| This paper describes the wave measurement and numerical modeling components of a regional monitoring and modeling system established for the south shore of Long Island, New York. The monitoring portion was begun in April 1998 and has produced a wealth of data on waves, currents, water level, and soundings at inlets. A directional spectral wave model incorporating nested grids with fine resolution at inlets provides an efficient and accurate means ... |

|
| This paper introduces a closed-form analytical solution of the one-dimensional (1D), depth-averaged linearized momentum and continuity equations that incorporates linear bottom friction and the non-linear wind stress. The solution describes wind-forced motion in a 1D basin with horizontal bottom as governed by water depth, basin length, bottom friction coefficient, wind speed, and fundamental frequency of an oscillatory wind. The solution displays in compact form general behavior and dependencies of the ... |

| Generation of Harmonics by Sea Breeze in Nontidal Water Bodies |

|
| The sea breeze introduces harmonics of its diurnal cycle into water bodies, which can be notable for strong sea breeze and microtidal and nontidal conditions. The harmonics can be of the same magnitude as those produced by bottom friction and dominate those produced by nonlinear terms in the equations of motion. A closed-form analytic solution of the linearized depth-averaged equations of motion including friction is discussed for the situation of ... |

|
| Tidal motion and inlet processes were investigated in Ponce de Leon (Ponce) Inlet, Florida and its bay channels through a 10-week data-collection campaign and two-dimensional numerical simulation modeling. Water level and current were measured at six locations spanning the ebb shoal, inlet, and bay channels. Measurements revealed that the inlet was flood dominated during the data-collection period. The flood dominance may have been enhanced by a net influx of water ... |

|
| The hydrodynamic feasibility of a proposed third inlet to East Matagorda Bay. Texas, was examined by application of a two-dimensional, depth-averaged hydrodynamic model. Wind-driven flows in this remote. shallow bay frequently dominate the weak astronomical tide. The bay presently has two connections to the Gulf of Mexico. one through a short flood-relief channel and the other through a long and circuitous navigation channel. The study had to consider whether installation ... |
