Wave-Driven Hydrodynamic Processes Over Fringing Reefs With Varying Slopes, Depths, and Roughness: Implications for Coastal Protection

Buckley, Mark L. (author), Lowe, Ryan J. (author), Hansen, Jeff E. (author), van Dongeren, Ap R. (author), Pomeroy, Andrew (author), Storlazzi, Curt D. (author), Rijnsdorp, D.P. (author), da Silva, Renan F. (author), Contardo, Stephanie (author), Green, Rebecca H. (author)

Wave breaking on the steep fore-reef slopes of shallow fringing reefs can be effective at dissipating incident sea-swell waves prior to reaching reef shorelines. However, wave setup and free infragravity waves generated during the sea-swell breaking process are often the largest contributors to wave-driven water levels (wave runup) at the...

Infragravity wave resonance over coral reef lined coasts

van Noort, Rieneke (author)

Coral reefs are vital to the prosperity of the world and the local communities by providing food and coastal protection. Coral reefs are home to 25% of marine life and have therefore gained the nickname ’rainforest of the sea’. However, the reefs are being damaged by climate change and human intervention, resulting in an alarming rate of...

Efficient and accurate modeling of wave-driven flooding on coral reef-lined coasts: On the interpolation of parameterized boundary conditions

Bertoncelj, Vesna (author)

Many coral reef islands are low-lying, which in combination with population growth, sea level rise and possibly more frequent extreme weather events is likely to result in increased coastal risk (e.g. Storlazzi et al., 2015). On smaller scales of O(10 km) wave-driven coastal inundation can be accurately predicted with advanced models such as...

Coral Reef Restorations Can Be Optimized to Reduce Coastal Flooding Hazards

Roelvink, Floortje E. (author), Storlazzi, Curt D. (author), van Dongeren, Ap R. (author), Pearson, S.G. (author)

Coral reefs are effective natural coastal flood barriers that protect adjacent communities. Coral degradation compromises the coastal protection value of reefs while also reducing their other ecosystem services, making them a target for restoration. Here we provide a physics-based evaluation of how coral restoration can reduce coastal flooding...

Hydro-Morphological Characterization of Coral Reefs for Wave Runup Prediction

Scott, Fred (author), Antolinez, Jose A.A. (author), McCall, Robert (author), Storlazzi, Curt (author), Reniers, A.J.H.M. (author), Pearson, S.G. (author)

Many coral reef-lined coasts are low-lying with elevations <4 m above mean sea level. Climate-change-driven sea-level rise, coral reef degradation, and changes in storm wave climate will lead to greater occurrence and impacts of wave-driven flooding. This poses a significant threat to their coastal communities. While greatly at risk, the...

Dynamics of resonant low-frequency waves over a schematized fringing coral reef

Gaido, Camila (author)

Low-lying islands are highly vulnerable to wave-induced flooding, with low-frequency waves (frequency <0.04Hz) being one of the main drivers. The impact of these inundations can increase due to wave resonance over coral reefs, which has been observed in the range of low-frequency waves. This study aims to understand the reef resonance...
