Using the Rainfall Mass Balance tool

FlowWorks' Rainfall Mass Balance tool can be used to compare rainfall sites to the average of related rainfall sites.

1. Open the Rainfall Mass Balance Tool

  1. Click Analyze. A drop-down menu appears.
  2. Click Rainfall Mass Balance.
  3. The Rainfall Mass Balance screen appears.

2. Select the Sites You Want to Average

Under Sites to Average, check-off the sites you want FlowWorks to determine cumulative averages for.


3. Select the Sites You Want to Compare

Under Sites to Compare, check-off the sites you want to compare with the sites to average.


4. Set a date range

You can select a predefined range using the date range menu, or manually input dates in the From and To fields.

If you want to save this query as a template, and you chose any predefined date range from the Date Range menu: the "date range" will always be in relation to the date that you run the template. For example, if you created a rainfall mass balance template in 2014, and the Date Range you chose was Last Year; when you run the template in 2017, FlowWorks will use data from 2016.


5. Click Plot Graph


The resulting Rainfall Mass Balance graph will open in a new page.


From the graph page, you can print the graph, download a PNG image of the graph, and export the associated data to a CSV file. Simply use the buttons found along the bottom of the page.
