The HIFLO experiment was organized by the Chesapeake Research Consortium to develop techniques for a coordinated response to emergencies and major environmental events. The purpose of the experiment was to learn how the Rappahannock Estuary, Virginia, responds to high river inflow and influx of sediment. Synoptic measurements of flow, salinity and suspended sediment were obtained at slack water along the 144 km estuary between March 28- April 1, 1978. Flow and sediment loads were monitored for nearly one month at four key points in the estuary and the watershed.
