Starting from version 2.7, QSWATMOD will adopt the use of a CSV format for measurement files containing stream discharge and water levels (groundwater levels or depth to water). QSWATMOD will automatically detect files with the "*.obd.csv" extension in your working directory, allowing users to select and match them with simulated output. The recommended names for the parameter estimation process are as follows:

• Observed stream discharge:
  • daily: stf_day.obd.csv
  • monthly average: stf_mon.obd.csv (use the end date of the month)
  • annual average: stf_ann.obd.csv (use the end date of the year)
• Observed groundwater level:
  • daily: gwl_day.obd.csv
  • monthly average: gwl_mon.obd.csv (use the end date of the month)
  • annual average: gwl_ann.obd.csv (use the end date of the year)
• Observed depth to water (values must be negative: groundwater level - land surface elevation):
  • daily: dtw_day.obd.csv
  • monthly average: dtw_mon.obd.csv (use the end date of the month)
  • annual average: dtw_ann.obd.csv (use the end date of the year)

Additionally, it's worth noting that missing values in the CSV files can be represented by either "-999" or an empty field ("").

Here is an example format of the measurement files.
