How to compare simulated with observed flow/level in XPSWMM

Prepare the observed flow data

A typical flow data file is a csv file with the following fields,

  • STATION: this is a text field, we can have more than one flow meter data saved in this column, and this column define the meter name
  • Date: use the mm/dd/yyyy format
  • Time: using the hh/mm format
  • Flow: that is the value to be compared to the results
  • generate time series, enter the first two time stamps, then just drag the cells to get fixed time interval time stamps series
  • make two copies of the time stamp columns, one for date, another for time
  • use the custom format to get date/time formatted
  • Save the file as csv file in Excel
