Overview

These RIFT runs used 24 hrs of precipitation based on the 3rd day of 6-hr QPF data (p06m_2018100812f0??.grb) with a flat temporal distribution for each 6-hr increment. Runs were for 10 days for Ochlockonee and Suwannee HUC4s, the other two ran 5 days.90-m resolution for all but Ochlockonee (60-m resolution, Tallahassee basin), no infiltration, no storm surge. These are WGS84. Caveats:·        Simulation results are based on forecasted precipitation data and are subject to change·        6-hr QPF data were used with a flat temporal distribution for each 6-hr period.·        Soils are assumed saturated and subject to minimal infiltration·        Storm surge and tidal dynamics are not included. Flood extents in areas impacted by either should be used with caution.·        The peak flood depth product is a representation of the peak flood depth at every grid cell, regardless of when the peak occurred.·        90-m resolution elevation data was used for this simulation. Local-scale topographic effects          may not be captured in the simulation·        Where data is available, National Levee Database is incorporated into the simulation.          Accuracy of levee representation is subject to the accuracy of the NLDB.·        Simulation results are intended to be used to estimate potential infrastructure impacts.      Use of the data for any other purpose should be done with caution. These data are not intended to be      used for life-preserving purposes.·        Dam operations are not included in the simulation but may greatly impact downstream flooding.
