meta -modeling for calibratio of HEC-HMS rainfall -runoff model

meta -heuristics algorithms have been widely used in simulation optimization problems such as automatic calibration of hydrological simulation models however despite the advances in computer power the time used for running a simulation model is a burden that modelers are usually faced with this paper considers the use of HEC-HMS hydrologic engineeering center hydrologic modeling systems model linked to a metaheursitic optimization algorithm for the purpose oc calibration the results are tested on tamar basin of gorganrood river basin in north of iran coupling HEC-HMS with an evolutionary algorithm imposes long run time especially when calibrating several events jointly.
