Objective Functions

There are four output measures (two flood events at two locations) defined that are combined into one objective function. The output measures compare measured and simulated maximum water level. AutoCal cannot compare time series of measured and simulated water levels during the simulation as only the maximum measured value is known. AutoCal is configured to do so by setting the statistic type to "Error of max". AutoCal selects the maximum simulated water level in the same period as covered by the target .dfs0 file.  I.e. the autocalibration using "Error of max" is not sensitive to the timing of peaks. Note that in this example the dfs0 files with observed data contains only one valid data set for each item. However, the period which the dfs0 files cover (mainly with empty/delete values) is important as it is used for picking the simulated max values as well.
