Thompson’s Bridge Replacement over Decker Cove, Southport, ME

Northstar Hydro, Inc. provided hydrologic, hydraulic and scour analysis to Maine DOT’s contractor for preliminary design for proposed replacement of the four span Thompson’s Bridge over Decker’s Cove. The project included unsteady flow modeling with model HECRAS and field monitoring to provide data on water elevations, velocities, and rate of flow through the bridge under a variety of storm and daily tide conditions. The bridge is shown in the first photo and the digital terrain model for the hydraulic model is shown in the second photo.
