Title:
Model parameter input files to compare effects of stream discharge scenarios on sediment deposition and concentrations around coral reefs off west Maui, Hawaii
Abstract:
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 models. These input files accompany the modeling conducted for the following publication: Storlazzi, C.D., Cheriton, O.M., Cronin, K.M., van der Heijden, L.H., Winter, G., Rosenberger, K.J., Logan, J.B., and McCall, R.T., 2023, Observations of coastal circulation, waves, and sediment transport along West Maui, Hawaiʻi (November 2017–March 2018), and modeling effects of potential watershed restoration on decreasing sediment loads to adjacent coral reefs: U.S. Geological Survey Open-File Report 2022–1121, 73 p., https://doi.org/10.3133/ofr20221121.

Why was the data set created?

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.

  2. How were the data generated, processed, and modified?
    Date: 2020 (process 1 of 1)
    Following the methodology established in the accompanying USGS Open-File Report (Storlazzi and others, 2022) these input files were created. Please see the report for full details. These input files were subsequently used by a coupled Delft3D Flow-Wave model (FLOW2D3D Version 6.03.00.62794; Delft3D-WAVE Version 3.07.00.62794), available at https://oss.deltares.nl/web/delft3d/, to simulate flow and waves over the nearshore reefs off West Maui. These Delft3D files were then used to force a Deltares Delwaq model (Version 5.08.00.63584M) to simulate sediment concentrations and deposition over the nearshore reefs off West Maui. The models were used to simulate two waves and currents scenarios (SC1 and SC2) in combination with two stream discharge options (Alt1 and Alt3).
