“…The factor of 3.6 in front of the wave height in Eq. (3) for ebb shoals is much larger than that for the depth over crest for depth-limited waves breaking on longshore bars (which is 0.66; see Larson and Kraus, 1989) because of the erosion by the ebb jet. Although Eq.…”

“…Technically, a detailed process based numerical model such as Xbeach (Roelvink et al 2009) or a semi-process based model such as SBEACH (Larson and Kraus 1989;Wise et al 1996) could be used here. However, due to the multiple simulations required in the PCR model procedure, the use of such a detailed numerical model as the structural function results in highly inefficient computations.…”

Estimating coastal recession due to sea level rise: beyond the Bruun rule

Accelerated sea level rise (SLR) in the twenty-first century will result in unprecedented coastal recession, threatening billions of dollars worth of coastal developments and infrastructure. Therefore, we cannot continue to depend on the highly uncertain coastal recession estimates obtained via the simple, deterministic method (Bruun rule) that has been widely used over the last 50 years. Furthermore, the emergence of risk management style coastal planning frameworks is now requiring probabilistic (rather than deterministic, single value) estimates of coastal recession. This paper describes the development and application of a process based model (PCR model) which provides probabilistic estimates of SLR driven coastal recession. The PCR model is proposed as a more appropriate and defensible method for determining coastal recession due to SLR for planning purposes in the twenty-first century and beyond.

“…A beach nourishment project in the United States normally includes the construction and maintenance of a wide berm and a high dune ͑Coastal Engineering Manual 2003͒. Empirical models based on an equilibrium beach profile have been developed to predict timedependent beach and dune erosion during a storm ͑Kriebel and Dean 1985; Kobayashi 1987;Larson and Kraus 1989͒. These models may be able to predict dune erosion within an error of a factor of about two if they are calibrated for each specific site.…”

Abstract:The prediction of berm and dune erosion during a storm is essential for storm damage assessment. Simple and transparent formulas for the cross-shore and longshore transport rates of suspended sediment and bed load on beaches are proposed and incorporated into a combined wave and current model to predict the berm and dune erosion under normally and obliquely incident irregular waves. Two small-scale experiments for two different berm profiles were conducted for the calibration of the developed numerical model. The calibrated numerical model is shown to predict the measured berm and dune erosion in these experiments as well as dune erosion measured in three large-scale tests with errors less than a factor of two. The numerical model is used to examine the effects of the wave period and incident wave angle on the berm and dune erosion. These effects are computed to be within a factor of two.
