Estimating sediment accumulation rates in Crane Creek, FL, from total suspended solids and streamflow measurements.  J.G. WINDSOR, M. CHANSON and D. STRACCIONE.  Dept. of Marine and Environmental Systems, Florida Institute of Technology, 150 W. University Blvd, Melbourne, FL 32901. Crane Creek was dredged in 1998. The key question addressed here is how long will it be until Crane Creek will require dredging again.  Based on mean discharge rates and mean TSS values at US 1, Babcock Street and Hickory Ditch, from 400 to 600 tons of total suspended matter are estimated to have been trapped within the Crane Creek system annually between 1998 and 2000.  Storm impacts may raise those estimates by a factor of 2.  Sedimentation rates based on these calculations alone (0.6 to 0.8 cm/yr) suggest that the Crane Creek will not have to be dredged again for more than fifty years.
