Coastal Flooding: Storms and Sea Level Rise

What water level and weather conditions are associated with coastal flooding in our community? What areas of our shoreline are most vulnerable and critical to our community?

Why this matters

Sea levels are rising, causing us to experience more flooding along our coastlines. This project helps coastal communities gather data to understand the unique flooding impacts in their towns, informing planning, forecasting, and decision-making.

Coastal Flooding: Storms and Sea Level Rise

With thousands of miles of tidal coastline, and the combined threats of storm surge and sea level rise, Maine’s coastal communities have a critical need to understand how weather and sea level contribute to flooding, erosion, and damage to their shores and coastal infrastructure. Help your community gather important flood impact data to inform resilience decisions.

  1. Read through the Prep & Collect tab on this site to familiarize yourself with the data collection protocol. We recommend printing and bringing along a data collection sheet in case you have no service or wifi in the field.
  2. Head to a coastal flood monitoring site (or anywhere along the coast) with a camera/smart phone and a friend – safety first!
  3. Take photos of the high water (or evidence of high water) that you’re observing and make note of the weather and broader flood impacts.
  4. Click on the Contribute tab to document your observations and upload your photos. You can use a computer to submit your observations once home, which may be easier than using your mobile phone.

Beyond building awareness of the often-invisible flooding occurring increasingly often in our coastal communities, data from this project is employed by planners, emergency management personnel, and flood forecasters in their work.

For Educators -

The Coastal Flooding Community Science project has been integrated into curriculum by fantastic educators from Southern to Downeast Maine.

Looking for ways to engage your students? Check out the curriculum resources developed by GMRI’s Education team to bring the project into your classroom.

For Organizations and Groups +

Land trusts, conservation groups, environmental ed centers, and community groups host coastal flooding educational events and coastal meet-ups all across Maine.

Interested to host coastal meet-ups in your area and engage your community in this project? The Community Engagement Package provides outreach and communications tools, instructions for hosting coastal meet-ups, brochures, and more!

Flood Forecasting and Tide Science +

Check out GMRI’s latest publication describing how data from these observations and a growing network of tide gauges along Maine’s coast are integrated to inform flood forecasting and planning.
