CIRCA works to enhance coastal resilience to coastal flooding and waves in Connecticut. Coastal flooding is caused by waves, storm surge, and high tide, particularly with increased sea levels. In coastal areas where there are also rivers, rainfall contributes to coastal flooding as well. Waves also contribute to shoreline erosion and information on waves is important for designing living shorelines.
Below is a brief summary description of our current Coastal Flooding and Waves projects. Click the Learn More button to read the detailed project description, or use the left navigation.
Road Flooding in Coastal Connecticut
The coastline of Connecticut is characterized by numerous inlets where the rivers and streams carrying runoff from land towards the ocean and the saline tidal waters of Long Island Sound intrude into the channels.
Waves in Long Island Sound and Living Shorelines Site Suitability Tool: NOAA CREST Project
The NOAA CREST project has significant wave heights for different return periods for all of Long Island Sound, measurements of waves in Old Saybrook and New Haven harbors, a review of design guidelines and tools for site assessment of living shorelines. This information is summarized in an online map viewer.
Advancing High Resolution Coastal Forecasting & Living Shorelines Approaches in the Northeast
The Advancing High Resolution Coastal Forecasting and Living Shorelines Approaches in the Northeast advances northeast regional forecasting for inundation from storms under future sea level rise scenarios and identifies policy barriers and potential solutions for the use of living shorelines in the northeast.
Jarvis Creek Sea Level & Flooding Variability
The Jarvis Creek Sea Level and Flooding Variability study in Branford, CT determined how downstream flood prevention activities affect areas upstream in terms of flooding frequency. The Institute provided a report.pdf with policy directions for the DEEP Office of Long Sound Programs for future consideration of similar upstream impacts.
Municipal Resilience Planning Assistance for Sea Level Rise, Coastal Flooding, Wastewater Treatment Infrastructure, & Policy
The Municipal Resilience Planning Assistance for Sea Level Rise, Coastal Flooding, Wastewater Treatment Infrastructure, and Policy project provides information for wastewater system vulnerability assessments, combined river and coastal flooding for pilot sites, and policy options for priority resilience projects for towns in the Sandy-impacted counties.
Resilient Coastal Communities under Wind & Flood Hazards
The Resilient Coastal Communities under Wind and Flood Hazards project will evaluate and compare trade-offs in residential home building designs to reduce risk of wind and flood damage in order to reduce coastal community vulnerabilities. The towns of Fairfield and Milford are participating in the study.
