Insufficient observed data for inflow or outflow when establishing your reservoir can lead to unsatisfactory validation results when comparing observed water levels with those calculated in the model. In such situations, the Reservoir Water Balance tool proves valuable. It relies on the difference between observed and calculated water levels to generate a balanced inflow time series. Subsequently, utilizing this time series can result in significantly improved validation results.

In the Update Series options, choose a time series station that will be used to balance the water levels. This is shown in Figure 2 below, where the series Balance P has been selected. After selecting this time series station, a Control Water Level series should be chosen to serve as the observed water level. Please note that the import file for the Control Water level must be in the correct format (see Figure 1). When the Compute button is selected, a notification indicating successful computation will appear.
