CLIENT: U.S. Fish Wildlife Hobe Sound National Wildlife  Refuge

LOCATION: Hobe Sound, Martin County,  Florida

PROJECT FEE: $75,000

Ross Engineering’s scope included an ICPR drainage study / hydrologic evaluation for impoundments F2 and F3 existing hydrologic exchange capacity base on impoundment geometry and a simplified representation of tidal dynamics. Assumptions for the evaluation were that flow velocities at hydrologic exchange points do not vary with depth, space or time during an ebb or flood tide. Our evaluation utilized both mathematical calculations and field observations. The tidal- prism volume and cross-sectional area of hydrologic exchange points (breaches or culverts) were estimated based on the survey data provided by SES. Flow velocity at surveyed hydrologic exchange points were gathered from field observations. The measured flow velocity was compared to the flow velocity theoretically necessary to transmit the full tidal prism volume across the surveyed hydrologic exchange points, to generate an estimate of hydrologic restriction present in the impoundment. An ICPR model was built and utilized to analyze the hydrology and provided results of the exchange.
