•Changes in wave dynamics under SLR are investigated for a large suite of 1D barrier reef profiles.•Impacts of SLR vary spatially and are strongly influenced by the bathymetry of the reef.•Wave velocities can increase or decrease with SLR.•Cyclonic wave forces are reduced for certain coral species on some reefs.•These changes may be beneficial to coral health and colony resilience in specific cases.
A one-dimensional wave model was used to investigate the reef top wave dynamics across a large suite of idealized reef-lagoon profiles, representing barrier coral reef systems under different sea-level rise (SLR) scenarios. The modeling shows that the impacts of SLR vary spatially and are strongly influenced by the bathymetry of the reef and coral type. A complex response occurs for the wave orbital velocity and forces on corals, such that the changes in the wave dynamics vary reef by reef. Different wave loading regimes on massive and branching corals also leads to contrasting impacts from SLR. For many reef bathymetries, wave orbital velocities increase with SLR and cyclonic wave forces are reduced for certain coral species. These changes may be beneficial to coral health and colony resilience and imply that predicting SLR impacts on coral reefs requires careful consideration of the reef bathymetry and the mix of coral species.
