FHICS – Successful forecast of Hurricane Ian impacts

Hurricane Ian was the first 2022 hurricane to make landfall in the continental USA with strong Cat 5 winds and large amounts of rain. The team of Deltares USA, Deltares Netherlands, USGS and NRL successfully applied the COSMOS modelling system to forecast hurricane Ian’s flood and morphological impact.

Successful air deployment of buoys with NRL partnership ahead of Hurricane Ian

On Monday, September 26th, 2022, 20 buoys were successfully deployed in the Gulf of Mexico ahead of Hurricane Ian as part of the NOPP Hurricane Coastal Impacts project. The deployment, which was facilitated by the U.S. Naval Research Laboratory, created a real-time sensor network to monitor Ian’s location and intensity as it advanced towards Florida’s Gulf Coast.

Sofar deploys Spotter Smart Moorings along coastlines

Sofar has started deploying Smart Moorings (Spotter buoys sensing surface waves, temperature, and barometric pressure along with water level from subsurface pressure sensors) in key locations in the Gulf and Atlantic coast to provide critical offshore observations (~20m depth) in tandem with cross-shore transects of USGS land-based water level observations to improve forecasts of hurricane impacts.

FHICS - Forecasting Hurricane Impacts on CoastS model system v1.0 ready

In the framework of the NOPP project “Hurricane Coastal Impacts” Deltares USA, Deltares Netherlands, USGS, NRL-SSC and IHE Delft are developing a forecasting system that can compute hurricane impacts of flooding, erosion and structural damage along the US Gulf of Mexico coast and the Eastern Seaboard.

COSMOS modelling system and visualization training

On July 5th, the Deltares modelling team was trained in the use of the COSMOS modelling system and visualization tool. The modelling system consists of large-scale surge (using SFINCS) and wave (using HurryWave) models for the Northern Atlantic and Gulf of Mexico which will be forced with COAMPS and/or GFS meteo. These large-scale models in turn drive SFINCS overland flood models and XBeach morphodynamic models. At the moment, 11 SFINCS models are implemented along the entire Gulf of Mexico coast and the South East Atlantic Coast. 100s of XBeach models are implemented along the sandy coastlines of the Gulf as well. In the training Roel de Goede instructed the other members on the workflow of running a hurricane event. Pictured are (from left to right: Ap van Dongeren, Roel de Goede, Panos Athanasiou, Maarten van Ormondt and Ellen Quataert. (Not pictured: Floor Roelvink and Kees Nederhoff). A screenshot of the NOPP event viewer shows the current (non-hurricane) wave conditions in the Northern Atlantic as computed using our new and fast HurryWave model.

Advanced Wind Retrievals From SAR Images at CSTARS

While the European Space Agency (ESA) provides SAR-derived wind fields over the ocean together with Sentinel-1 SAR imagery, users have to apply their own algorithms to retrieve wind products from SAR images from other satellites.

April 2022 – Field Testing at the USACE Field Research Facility in the Outer Banks, North Carolina

In preparation for land-based sensor deployments during the 2022 Hurricane season, scientists from the U.S. Geological Survey (USGS) conducted field tests at the U.S. Army Corps of Engineers (USACE) Field Research Facility (FRF) in Duck, North Carolina in late March 2022.

TerraSAR-X Radargrammetry Products From Airbus Defence and Space

The University of Miami group received first radargrammetry results from industry partner Airbus Defence and Space in December. These land topography products are based on a set of SAR images of the area on the Florida panhandle where Hurricane Michael made landfall in 2018. The test images were acquired between August 26 and September 1, 2021, as reported earlier.

Hurricane Michael (2018) Imaged by Sentinel-1 SAR

The European satellites Sentinel-1A and -1B acquire synthetic aperture radar (SAR) images of coastal regions of the U.S. on a regular basis, and they can be programmed to acquire additional images at times of hurricanes and similar events of interest. The European Space Agency makes all Sentinel-1 imagery available to interested users in near real time, free of charge. Together with the radar intensity images, derived wind fields are provided.
