Restoring Natural Flow of Gooseneck Cove

Scientists from Applied Science Associates (ASA) have teamed with staff and volunteers from Save The Bay to study the effects of man-made constrictions on circulation in Gooseneck Cove, an estuary located in Newport, RI.

Several man-made structures exist along Gooseneck Cove, including a failing concrete dam and numerous under-road culverts, which limit the flow of ocean water into the cove. This has led to the degradation of both water quality and salt marsh habitat in the cove. In particular, the decreased flow of ocean water leads to lower salinities in the cove. This has allowed foreign species to invade and outcompete the native salt marsh plants.

Restoration efforts are currently underway to improve the water quality of Gooseneck Cove. These efforts are being guided by NOAA and the Natural Resources Conservation Service. Working through the Rhode Island Corporate Wetlands Restoration Partnership (RI-CWRP), a joint effort among corporations, government agencies and non-profit environmental groups, ASA has worked to evaluate various restoration alternatives.

The ASA team used computer models of circulation in Gooseneck Cove in conjunction with water quality data collected by volunteers from Save the Bay to evaluate the effects of different restoration plans. The results of the computer modeling show that the removal of the concrete dam, along with increasing the number and size of the culverts, will significantly increase tidal flow in the cove and help to restore the natural salt marsh habitat.

The next step is for the government agencies to decide on a final restoration plan, in light of the results of ASA's study, and to develop a schedule for implementation. This effort will be aided by another CWRP member, EA Science and Technology, Inc.
