Shoreline Change (Beach) SAMP

Shorelines are constantly changing, and Rhode Island coastal communities are increasingly experiencing the impacts. Storm waves can erode beaches and flood developed areas, while rising sea levels subsume land. Communities are asking how they can protect people and property, as well as vital infrastructure such as drinking water supplies, utilities, and roadways.

STORMTOOLS: Coastal Environmental Risk Index (CERI)
Uses a state of the art modeling tool (ADCIRC and STWAVE) to predict storm surge and wave, combined with shoreline change maps (erosion), and damage functions to construct a Coastal Environmental Risk Index (CERI).

STORMTOOLS Interactive Maps

Rhode Island Floodplain Mapping

STORMTOOLS For Beginners

STORMTOOLS for Beginners is a one-map stop for all residents of Rhode Island to better understand their risk from coastal inundation. This map allows you to enter an address in Rhode Island, and get answers to 3 questions about your property:

  1. Is my property vulnerable to STORM SURGE?;
  2. How DEEP will the water be on my property during a 100-year (1% chance) coastal storm?; and
  3. Will projected SEA LEVEL RISE affect my property?

Step-by-Step Quick Guide to accessing STORMTOOLS Mapping


STORMTOOLS For Municipalities is a one-map stop for Rhode Island’s municipal officials and decision makers of Rhode Island to better understand their risk from coastal inundation. This map provides information on flooding impacts from storms and sea level rise, as well as information on the location of critical infrastructure, coastal structures and population density.

The Rhode Island Coastal Resources Management Council, in coordination with the University of Rhode Island, is preparing a plan to help find solutions these problems, which are threatening communities in many areas along the state’s coast. The Beach SAMP aims to improve the coastal resiliency of cities and towns throughout Rhode Island to the threats of erosion and flooding caused by storms events or sea level rise. Using up-to-date research and expertise from a wide range of public and private sectors, the Beach SAMP will help inform state and local policy and planning initiatives. Part of this partnership includes the maintenance of the Beach SAMP web site by Rhode Island Sea Grant.

If you would like to stay involved in the SAMP process, please join the Beach SAMP List Serve at http://www.beachsamp.org/get-involved/. Or if you have any questions concerning this effort, please contact Laura Dwyer at CRMC – (401) 783-7886 or at ldwyer@crmc.ri.gov.

The Beach SAMP is supported by funding from the Rhode Island Bays, Rivers, and Watersheds Coordination Team, URI Coastal Resources Center, Rhode Island Sea Grant and the URI Coastal Institute.
