Simulation and visualization of coastal tsunami impacts from the SAFRR tsunami source To further extend the scope of the Science Application for Risk Reduction (SAFRR) project, detailed hydrodynamic simulations were run at three harbor locations in California. For the locations of 1) Oakland/Alameda, 2) Half Moon Bay, and 3) Santa Cruz, simulations at approximately 5-m resolution were performed using the high-order Boussinesq-type model COULWAVE. The Oakland/Richmond simulation area focuses on the major port facilities in the area and the Half Moon Bay and Santa Cruz simulations focus on Pillar Point Harbor and Santa Cruz Harbor, respectively. Tags: Geography, Marine Geology Model parameter input files to compare effects of stream discharge scenarios on sediment deposition and concentrations around coral reefs off west Maui, Hawaii This dataset consists of physics-based Delft3D model and Delwaq model input files used in modeling sediment deposition and concentrations around the coral reefs of west Maui, Hawaii. The Delft3D models were used to simulate waves and currents under small (SC1) and large (‘SC2’) wave conditions for current stream discharge (‘Alt1’) and stream discharge with watershed restoration (‘Alt3’). Delft3D model results were subsequently used as forcing conditions for Delwaq models to simulate sediment transport and dispersion. The Delwaq models were used to simulate sediment transport and concentrations under the same two wave and stream discharge scenarios. The Delwaq models were run using forcing conditions generated by...

We used statistics, machine learning, and numerical modelling to develop the set of RCPs, which can be used to accurately represent the shoreline hydrodynamics of a large variety of coral reef-lined coasts around the globe. In two stages, the data were reduced by clustering cross-shore profiles based on morphology and hydrodynamic response to typical wind and swell wave conditions. By representing a large variety of coral reef morphologies with a reduced number of RCPs, a computationally feasible number of numerical model simulations can be...

The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast will respond to the hydrodynamic forcing. Storm-induced water levels, due to both surge and waves, are compared to coastal elevations to determine the probabilities of three types of coastal change: collision (dune erosion), overwash, and inundation.
