“…A detailed description of the application of the JPM model to simulate storm erosion statistics at Narrabeen beach (in the absence of SLR) is given in , and hence only a brief summary is provided herein. For the purposes of the present model application, following common practice in the study area (Lord and Kulmar 2000;Kulmar et al 2005), a storm event is defined as a single meteorological event where the significant wave height exceeds 3 m. Following Kriebel and Dean (1993), a sine-squared function (above the threshold wave height) is assumed to represent the time evolution of storm events. The data employed in this model application included 36 years of non-directional offshore wave data, 14 years of directional offshore wave data, and 90 years of water level data.…”

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

2011

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.

“…The I R index provides a measurement of potential beach retreat and is used for the dynamical calculation of the shoreline retreat based on the convolution method of Kriebel and Dean (1993). I R values depend on the percentage associated to the maximum beach retreat (R max ) normalized with respect to L (Benassai et al, 2009).…”

“…I R values depend on the percentage associated to the maximum beach retreat (R max ) normalized with respect to L (Benassai et al, 2009). R max is evaluated as the maximum value of the general solution associated to the Kriebel and Dean (1993) convolution method…”

Sea wave modeling with X-band COSMO-SkyMed<sup>©</sup> SAR-derived wind field forcing and applications in coastal vulnerability assessment

et al. 2013

Abstract. In this paper, X-band COSMO-SkyMed © synthetic aperture radar (SAR) wind field data are first used to force coastal wind wave modeling for both sea wave numerical simulation and coastal vulnerability assessment purposes. The SAR-based wind field retrieval is accomplished by resolving the SAR-based wind speed and wind direction retrieval problems independently. The sea surface wind speed is retrieved through the azimuth cut-off procedure, and the sea surface wind direction is determined by the multiresolution analysis of the discrete wavelet transform. The wind wave modeling is based on the third-generation Simulating WAves Nearshore (SWAN) model, which is used for sea wave state estimation in coastal and inland regions. The coastal vulnerability assessment is provided by means of a key parameter, known as impact index, which evaluates the coastal risk due to the inundation of the inshore land. Experiments consist of SWAN numerical simulations run with respect to some relevant wave storms recorded in the southern Tyrrhenian Sea on 2010, with applications in coastal vulnerability assessment along the Sele coastal plain. Experimental results show the benefits of blended wind field products, provided by European Centre for Medium Weather Forecast (ECMWF) model winds and SAR-based wind field estimations, for both wind wave modeling and coastal vulnerability assessment purposes.

Critical Width of Barrier Islands and Implications for Engineering Design

Abstract:The critical width of a barrier island is defined as the smallest cross-shore dimension that minimizes net loss of sediment from the island over periods from decades to centuries. This concept is of importance for large-scale restoration of barrier islands which involves rebuilding these islands to a specified geometry. Within constraints of coastal forcing and geologic and regional characteristics at the site, islands having critical width will capture deposition of washover sediment onto the subaerial beach over the project lifetime. This study reviews previous investigations of barrier island critical width and applies a newly-developed model of barrier island migration, consolidation, and overwash to assist engineering design.
