Citizen Science for King Tide Flooding

Broward County , FL , United States
At a Glance: Low-lying coastal areas of Broward County can be impacted by flooding from high tide events. To help document locations and severity of flooding, Broward County launched a citizen science effort that encouraged citizens to submit geotagged pictures of flooding via their smartphones.
The challenges this project addresses are: Flooding, Coastal & Tidal Flooding, Sea Level Rise, Education, Citizen Engagement, Civic Technology
Low-lying coastal areas of Broward County can be impacted by flooding from high tide events. These often time occur during the fall (August-November) with the peak usually occurring the King Tide (Highest tide of year) in October. Improving data about the timing, locations and severity of flooding due to King Tides is a top priority in the County to addressing flood concerns.
Broward County used/is using citizen science to address this/these challenge(s).
The County issued groups "King Tide Kits," refractometers, to community groups to help track and report tidal flooding at six flood-prone sites. Citizen participants were then encouraged to submit pictures of flooding using an application on their smartphones. https://bcgis.maps.arcgis.com/apps/StoryMapCrowdsource/index.html?appid=352ee6d238214f9b94f9eff0f736f1f1
Outcomes:
  • Improved document of current flood risk in coastal areas
  • Help citizens visualize the impacts of future sea level rise in their community
  • Verify climate change models by comparing model predictions with the high-tide reality
