“…Although various equations have been proposed (e.g. Collins, 1970;Weggel, 1972;Komar, 1998), these either do not take the ratio between H o /L o into account, or ignore the slope of the sea floor. An alternative method was therefore proposed by Le Roux (2007).…”

“…7 and 8 depend on beach slope, which can be estimated as an average bottom slope from the break point to one wavelength offshore (Smith 2002), and characteristics of the wave (Weggel 1972;Smith and Kraus 1991). Detailed surveys of the surf zone are necessary for measuring this parameter as the available bathymetric data are not of sufficiently fine resolution.…”

A high-resolution storm surge model of Apalachee Bay in the northeastern Gulf of Mexico is developed using an unstructured grid finite-volume coastal ocean model (FVCOM). The model is applied to the case of Hurricane Dennis (July 2005). This storm caused underpredicted severe flooding of the Apalachee Bay coastal area and upriver inland communities. Accurate resolution of complicated geometry of the coastal region and waterways in the model reveals processes responsible for the unanticipated high storm tide in the area. Model results are validated with available observations of the storm tide. Model experiments suggest that during Dennis, excessive flooding in the coastal zone and the town of St. Marks, located up the St. Marks River, was caused by additive effects of coincident high tides (*10-15% of the total sea-level rise) and a propagating shelf wave (*30%) that added to the locally wind-generated surge. Wave setup, the biggest uncertainty, is estimated on the basis of empirical and analytical relations. The Dennis case is then used to test the sensitivity of the model solution to vertical discretization. A suite of model experiments is performed with varying numbers of vertical sigma (r) levels, with different distribution of r-levels within the water column and a varying bottom drag coefficient. The major finding is that the storm surge solution is more sensitive to resolution within the velocity shear zone at mid-depths compared to resolution of the upper and bottom layer or values of the bottom drag coefficient.

“…Once the highest water depth is determined, the maximum depth-limited breaking wave height and minimum breaking wave period, corresponding to maximum wave steepness, are The lateral capacities are given per unit length of the bridge span Nat Hazards estimated by use of the analytical relations given by Weggel (1972). We chose a slightly smaller wave height (H=h % 0:52-0.55) and larger wave period so that the waves do not break prior to the interaction with the structure.…”

Vulnerability assessment of coastal bridges on Oahu impacted by storm surge and waves

et al. 2015

Vulnerability assessment of four selected prototype coastal bridges on the island of Oahu, Hawaii, to the combination of storm surge and waves is presented. The maximum storm surge condition is estimated by considering an extensive series of simulated hurricanes making landfall on the island of Oahu, where the bridges are located. For the given extreme environmental conditions, wave loads on the deck of the selected bridges are calculated by use of several theoretical and computational approaches, including Euler's equations (OpenFOAM), the Green-Naghdi nonlinear equations, linear long-wave approximation and existing simplified, design-type force equations. Multiple scenarios of the relative location of the bridge deck and the still-water level are studied to determine the maximum possible wave loads on the bridge decks. Vulnerability of the coastal bridges to storm wave loads is determined by comparing the capacity of the bridge to the wave-induced loads on the structure.
