CAT 3 Storm Scenario Development for
the port of PROVIDENCE
URI researchers developed a plausible storm scenario to elicit stakeholder concerns and discover cascading consequences. This page describes the process URI research used to develop storm visualizations to support stakeholder discussions.
1. Identifed Storm Scenario
- The scenario identified was a category 3 hurricane (winds of 111-130 mph) hitting Rhode Island in late summer at high tide.
- The track of the storm would bring it from the south at 40 MPH passing just west of Narragansett Bay, making landfall on somewhere near the Connecticut, Rhode Island boarder.
- For the Northeast US, a Cat 3 Hurricane has a return period of approximately 60 years , or a 1.7% chance of impacting the region in a given year. This scenario represents the worst case scenario track for a Cat 3, making it a greater than 100 year storm.
2. Modeled Surge Height
3. Created Visualizations
- Using "Bathtub" modeling, researchers developed surge depth maps. "Bathtub" modeling shows height of surge overland.
- "Bathtub" modeling does not take into account wave heigh and movement of water over the inundated areas of land.
- This model assumes that the Fox Point Barrier is not overtopped.
- After creating "Bathtub" models, 3D visualizations can be made using GoogleEarth.
- The images below show flooding at sites throughout the port of Providence. These images can now be show to port stakeholders to prompt and support discussion on potential impacts and solutions.
- With photoshop editing, debris can also be depicted.
