WMS:Floodplain Delineation
The floodplain delineation portion of the stochastic modeling uses the results from each HEC-RAS model to develop a floodplain for each run. The floodplain delineation is the same model used by WMS to perform individual floodplain delineations.
The only parameters at this point that can be varied within a range of probable answers the search radius of the floodplain delineation. This is done by setting the search radius in the Floodplain Delineation Options be a negative number. This negative number is a key number and should be unique for each stochastic variable created. When running the stochastic simulation WMS will substitute the simulation specific parameter for the defined key. Then setup a stochastic variable for Floodplain in the Stochastic Run Parameters dialog. A key value (matching the key as defined in the materials property) starting value, min value, max value, standard deviation and distribution type.
