The USGS Long Island Sound Partnership Compound Flood Hazard Web Map Application is an interactive tool developed by the U.S. Geological Survey’s New York Water Science Center that helps users explore the combined impacts of multiple flooding drivers across the New York and Connecticut coastal regions. Drivers of compound flooding included in the assessment were precipitation, coastal (storm surge, tidal), and groundwater emergence, which when combined can lead to more severe and widespread inundation than from any single cause alone.

The map visually displays hazard rankings and spatial patterns of flood drivers so that planners, emergency managers, researchers, and the public can better understand where these flood hazards are most likely to coincide, thus supporting local decision making for flood mitigation, coastal planning, and resilience strategies. The application is based on USGS models and ongoing research into regional flood processes.

Created by the Northern Institute of Applied Climate Science, the Adaptation Workbook provides a structured, five step process designed to help natural resource professionals and landowners translate broad climate trends into specific, actionable management plans. By moving from defining project goals to monitoring long term results, the workbook helps users assess local vulnerabilities and identify custom adaptation tactics. This flexible framework is applicable across diverse landscapes including forests, urban areas, and agricultural lands ensuring that climate data becomes a practical tool for protecting ecosystems rather than just a collection of abstract projections.

This resource page also offers a variety of supporting materials including: the full Forest Adaptation Resources guide, “Quick Guide” versions for rapid assessment, and a library of real-world demonstration projects that showcase successful adaptation in practice.

The LINAP Embayment Water Exchange Study looked at how water exchange practices could affect the nitrogen impairments in embayments. A water exchange practice changes the amount, speed, or direction of water moving through an area. The results of the study show that water exchange techniques are not effective in large waterbodies like most of Long Island’s embayments. Often, the physical size of the water exchange practice is small compared to the large waterbodies to which they are applied, which means their impact is limited. Water exchange projects may be useful, however, for smaller Long Island waterbodies, where the volume of increased water exchange approaches the volume of the overall waterbody. The goal of the study was to provide communities with basic information on water exchange practices suitable for Long Island.

This project restored 46 acres of the Great Meadows Marsh in Connecticut that was degraded from dredge material that was dumped on site, poor drainage, and sea level rise. The marsh was also overrun with invasive plants and mosquitoes. A controlled fire was started to kill the invasive reeds growing in the marsh. Then a construction crew removed invasive plants and the dumped dredge material. Lastly, channels were carefully dug for tidal flushing which will allow the marsh to keep pace with sea level rise. Soil hummocks were constructed for Salt Marsh Sparrow habitat. Now the area continues to be monitored, assessed for resiliency, and provides a field for innovative solutions to be tested in.
