In DataSight, the calculated results are continuously and automatically refreshed after adding or editing Chainage measurements and are displayed in the same measurement units as the data being entered.

However, there is also an option to override these calculations and enter the values manually.

Manually enter gauging parameters

1. Select the Gaugings tab in the Main Panel.
2. Either double click on the relevant Gauging row or once the selected gauging is highlighted, click on the Gaugings ribbon tab and select Edit Gauging. The New Gauging window appears.
3. Click the Manual Override checkbox in the Calculated Properties section.
4. Enter the Total Area, Mean Velocity and Total Discharge.
5. Click Save. Any associated Chainages will no longer be displayed with the Gauging in the Gauging list.

Revert to DataSight generated values

1. In the New Gauging window, click the Manual Override checkbox off in the Calculated Properties section.
2. Click Save. The associated Chainages are again available within the Gaugings list.
3. Either double click on a relevant Chainage row or once a Chainage is selected, click on the Gaugings ribbon tab and select Edit Chainage. The Chainage window appears.
4. Click Save. Calculated gauging properties are now displayed in the Gaugings List, and within the Gauging window.

Refer to Gauging Calculations for further information on the usage and derivation of gauging parameters.
