Summary
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 the corresponding Delft3D [...]

Coral reefs are effective natural coastal flood barriers that protect adjacent communities. Terrestrial sediment discharging from watersheds off West Maui, Hawaii, USA, has been documented as a primary stressor to local coral reefs, causing coral reef health to decline. The objective of this study was to assess in which watersheds terrestrial restoration would most benefit the adjacent coral reefs by reducing sediment impacts for both flood and storm conditions. A series of physics-based Delft3D and Delwaq model simulations were used to evaluate which watersheds resulted in sedimentation on the seabed and suspended sediment in the water column on which adjacent coral reefs.
