'Catch the King' Tide

App-Observed King Tide Extents vs. Nov. 5th Forecast of Predicted Maximum Flooding Extents, 08:00-11:59 AM EDT

"Catch the King" was a citizen science GPS data collection effort centered in Hampton Roads, VA, that sought to map the King Tide's maximum inundation extents with the goal of validating and improving predictive models for future forecasting of increasingly pervasive "nuisance" flooding. 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 App every few steps along the water's edge during the high tide on the morning of Nov. 5th, 2017. 

Response from the event's dedicated volunteers, fueled by the local media partners' coverage leading up to the event, and over 35 separate volunteer training events held all over Hampton Roads resulted in 510 known participants collecting 53,006 time-stamped GPS maximum flooding extent measurements and 1,126 geotagged photographs of the King Tide flooding during the event.

Map of Citizen Science SLR App Observations vs. Model-Predicted Maximum Flooding Extents

 

GPS high water mark data appear on the embedded map above as blue dots. Red points correspond with Tidewatch and StormSense water level sensors. This interactive map presents forecasted maximum flooding extents for the King Tide on Sunday, 11/05/2017, from 08:00-11:59 AM EDT, with the Sea Level Rise App data serving as an effective validation of the model's predictions. Evaluate the comparison for yourself using the measuring tools and print your own maps using the embedded interactive map's toolbar. Inundation forecast results are depicted using a range of blue hues correponding with flood depths, and are advised by VIMS' hydrodynamic models and by Tidewatch.

Interested volunteers can participate in future citizen science field data collection events like this one by downloading the "Sea Level Rise" application onto their smartphones, 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.
