There are two ways to validate data in HEC-RTS: Icons Mode and List Mode.
- Icons Mode uses the time series icons selected directly from the map window or through the Data Status Summary.
- List Mode relies on a preconfigured Data Validation List.
This guide walks you through using both modes in the Data Validation Editor.

Using Icons Mode from the Data Status Summary
- Launch HEC-RTS and open your watershed.
- Navigate to the Acquisition tab.
- From the Reports menu, select Data Status Summary.
- In the table, hold down the SHIFT key and select the datasets you want to validate.
- From the View menu, select Validate.
- Alternatively, right-click a selected row and choose Validate.
- The Select Data Validation Sets dialog will open.

- Adjust the settings as needed and click OK.
- The Data Validation Editor will open, displaying the selected datasets.
Using Icons Mode from the Map Window
To validate data using all time series icons on the map:
- Launch HEC-RTS and open your watershed.
- Navigate to the Acquisition tab.
- Click Data Validation.
- Choose Icons (if available). If no validation lists exist, it defaults to Icons Mode.
- Adjust the settings in the Select Data Validation Sets as needed and click OK.
- The Data Validation Editor will open.
Using List Mode
You must have at least one Data Validation List configured to use List Mode. See the related guide for setup instructions.
- Launch HEC-RTS and open your watershed.
- Navigate to the Acquisition tab.
- Click Data Validation.
- Choose Lists and select the appropriate list from the dropdown menu.
- Adjust the settings in the Select Data Validation Sets as needed and click OK.
- The Data Validation Editor will open.
