"Catch the King" is a citizen-science GPS data collection effort centered in Hampton Roads, VA, that seeks to interactively map the King Tide's maximum inundation extents. The goal is to validate and improving predictive model accuracy for future forecasting of increasingly pervasive "nuisance" flooding. The maximum king tide inundation forecast for Oct. 27, 2019 is shown in the map below:
10/27/2019 - Catch the King Tide Data Map
- Blue GPS data points were collected by volunteers to effectively breadcrumb/trace the high water line by pressing the 'Save Data' button in the Sea Level Rise (SLR) App every few steps along the water's edge. These GPS data are collected during the king tide in the morning on Oct. 27th, 2019. Click on a point to zoom in, disaggregate points, and view timestamps.
- Red points correspond with water level sensors in the NOAA (10), USGS (18), VIMS (2), and StormSense (28) networks, which are aggregated and ingested into VIMS' Tidewatch Forecasting Network. Before Catch the King, forecasts will be displayed; after the event observations and predictions will be displayed and archived at each station location when selected, For Tidewatch Charts, current water level forecast information is available for up to 36-hrs from the present time.
- The blue flood layer superposed with satellite imagery on this interactive map represents forecasted maximum flooding extents for the King Tide happening in Hampton Roads on Saturday, 10/27/2019, from 09:00 AM - 02:59 PM EDT, with the Sea Level Rise App data serving as an effective validation of the model's predictions. This layer represented inundation extents predicted by VIMS' models months before the king tide event. These tidal inundation forecast results are then updated days before Catch the King to account for near-term weather-related impacts on the king tide as a comprehensive storm tide forecast using a range of blue hues corresponding with flood depths, and are advised by VIMS' hydrodynamic models and by Tidewatch.
"Catch the King" Initial Participation Statistics
...ranked by region where the greatest number of volunteers and high water marks were collected
*The "Outside Hampton Roads and Training Region" also incorporate data from separate groups who mapped across many cities and counties including HRSD, Master Naturalists, Girl Scout, and Boy Scout Troops, among others.
Response from the event's numerous volunteers, fueled by the local media partners' coverage leading up to the event, and 28 separate volunteer training events held all over Hampton Roads resulted in an estimated 291 known participants collecting 36,218 time-stamped GPS maximum flooding extent measurements and 218 geotagged photographs of the King Tide flooding during the event.

WHRO Public Media's video and audio advertisements for the event played a significant role in been getting out the word about Catch the King 2019. Check out their video!
Tracking tidal flooding is important, as it gives us a tangible glimpse into the anticipated height of mean tides less than half a century from today. As shown in the interactive plot below, Norfolk in Hampton Roads, VA, has the highest rate of relative SLR acceleration on the US East Coast, as noted in the recent VIMS Report.

Interested volunteers can participate in future citizen science collection events by downloading the "Sea Level Rise" application onto their smartphone, and using the app to trace the high water line from varying locations where they observe inundation. The data will be collected and used to help scientists, educators, and community leaders better understand the risks imposed by the rising tide.

Event data will be publicly posted here (once reviewed and finalized) in the week after Catch the King for interested parties to access and download directly.
Attributions: Volunteers of 'Catch the King' Tide 2019 collected these data using the Sea Level Rise mobile application developed by Wetlands Watch and Concursive, Inc. Catch the King 2019 was sponsored and supported by the Hampton Roads Sanitation District and AECOM, WHRO Public Media, The Virginian-Pilot, the Daily Press, and the CCRFR and orchestrated/managed by Qaren Jacklich and a dedicated team of tide captains and teachers. GPS volunteer data were shared with VIMS for public dissemination via Concursive, Inc. and some schools and volunteers directly.
