As the model complexity increases, the number of parameters thatinfluence water and contaminant movement, are varied within acceptable ranges in an attempt tomodifications to parameters that govern travel times and concentration levels. Parameters, which Once the distances have been defined, the calibration requires wells, receptor locations, travel time and magnitude). Location is predetermined by the user with respect to monitoring impacts two of them ( 3 crucial elements associated with any calibration exercise, and Kthe magnitude of the monitored concentration. Therefore, time, location and magnitude aremonitoring well), the model must predict the correct arrival time at the correct location, matchingWhen calibrating a groundwater model to monitored information (ways it is used in the mathematical constructs of ...
