Manual Calibration

SWAT+ Toolbox provides two options for calibration: Manual Calibration and Automatic Calibration.

SWAT+ Toolbox assists manual calibration by facilitating the following steps:

• Set parameters
  
• Run SWAT+ with new parameters
  
• Calculate Performance indices and plot graph
  

Users can go through these steps until they obtain satisfactory results. Set a parameter by double-clicking the value you want to change in the ‘Value’ column in the parameters panel (Fig. 12). Then Click Run SWAT+ to run the model with the new parameters.

Once done, click on the ‘refresh performance’ button to calculate new performance indices. In the case that you have more than one observation, you can go to the graphical evaluation of each observation by clicking on it in the ‘performance index panel’. Remember to do a model check once you get satisfactory results to see your model's potential issues.
