Every fall, we get higher full and new moon tides - as much as 2 feet higher - because the moon is closer to the earth. These Perigean High Tides are often nicknamed "King Tides" and in low lying regions like ours they cause increased nuisance flooding.
This year, the highest tide happens on November 5, 2017, and we have a unique event planned for that day: a first-ever public, regional flood mapping event using our Sea Level Rise flooding app. Making this event even more unique is its sponsorship by our two regional newspapers - the Virginian Pilot and the Daily Press - as well as our regional NPR station, WHRO, and a commercial TV station, WVEC.
The two images above preview what we will get. The image to the left above displays an outline of the flooding we experienced during the September, 2015 King Tide. The mapping was done with our phone app . The app data was exported to our friends at the Virginia Institute of Marine Science (VIMS) to help them with their flooding models. Dr. Derek Loftis at VIMS has been collaborating with us on this work.
The image to the right above shows those same 2015 data points laid on top of a VIMS map showing the expected inundation on November 5, 2017, the highest King Tide of 2017. These VIMS maps will help us target our volunteers to map that day. We hope to cover all the cities and counties that make up Hampton Roads.
Stay tuned for more updates - we're doing a soft launch on August 14, test events will be held through Sept and Oct, leading up to the November 5 event.
