Description:
Abstract:
A process-based wave-resolving hydrodynamic model (XBeach Non-Hydrostatic, ‘XBNH’) was used to create a large synthetic database for use in a “Bayesian Estimator for Wave Attack in Reef Environments” (BEWARE), relating incident hydrodynamics and coral reef geomorphology to coastal flooding hazards on reef-lined coasts. Building on previous work, BEWARE improves system understanding of reef hydrodynamics by examining the intrinsic reef and extrinsic forcing factors controlling runup and flooding on reef-lined coasts. The Bayesian estimator has high predictive skill for the XBNH model outputs that are flooding indicators, and was validated for a number of available field cases. BEWARE is a potentially powerful tool for use in early warning systems or risk assessment studies, and can be used to make projections about how wave-induced flooding on coral reef-lined coasts may change due to climate change.
These data accompany the following publication: Pearson, S.G., Storlazzi, C.D., van Dongeren, A.R., Tissier, M.F.S., and Reniers, A.J.H.M., 2017, A Bayesian-based system to assess wave-driven flooding hazards on coral reef-lined coasts: Journal of Geophysical Research—Oceans, https://doi.org/10.1002/2017JC013204.
Purpose:
Low-lying tropical coasts fronted by coral reefs are threatened by the effects of climate change, sea-level rise, and flooding caused by waves.  However, the reefs on these coasts differ widely in their shape, size, and physical characteristics; the wave and water level conditions affecting these coastlines also vary in space and time. These factors make it difficult to predict flooding caused by waves along coral reef-lined coasts. We created a system (“BEWARE”) that estimates how different wave, water level, and reef combinations can lead to flooding. This tool tells us what information is needed to make good predictions of flooding. BEWARE can be used to make short-term predictions of flooding in early warning systems, or long-term predictions of how climate change will affect flooding caused by waves on coral reef-lined coasts.

Process_Step:
Process_Description:
The following steps were used in development of the model. For an in-depth discussion of processing, see Pearson and others (2017). 1. Schematize the reef and forcing conditions, and formulate a range of input parameters based on field measurements and typical values. 2. Simulate nearshore hydrodynamics for the full range of parameters using the validated process-based wave and water level XBeach Non-Hydrostatic (XBHN) model to create a synthetic database of hydrodynamic responses to extrinsic forcing and intrinsic coral reef geomorphology. 3. Develop a Bayesian network and train with model results. 4. Validate the Bayesian network by comparing predictions to field observations. 5. Assess the performance of the Bayesian network using techniques such a Log-Likelihood ratios and confusion matrices.
