Observed WQ data is the observed concentrations of constituents used for calibration/validation. The Observed Dataset Editor (Figure 7.1) enables the user to create one or more Observed Datasets and to enter time series of observed data into HEC-ResSim to enable comparison with model results. There are no prerequisites for completing the Observed Dataset, and it is not used in any WQ Datasets.
