When using the stochastic hydrologic/hydraulic/floodplain delineation tools it is possible to generate an annual exceedance probability map. This is done by generating inundation maps that consider the range of all possible floods for all return periods. The result is a map that identifies the annual exceedance probability of flooding for every TIN vertex. For example if a point is flooded 10 times in 1000 simulations then it would represent the .01 probability. The Return Period → Feature Objects command allows you to generate contours from the AEP map for specified return periods. You should remember that such a map does not represent a solution from a single set of input parameters, but is rather the composite of several hundred or thousand simulations.
