Import flow measurements
Application
When the <Processing of Flow Measurements> function is selected the following form will be presented.
Station Codes
First you have to select a station code. This is the station, you want to process the flow measurement for. Select a station by clicking the checkbox in the stations list.
Current meters
Select a currentmeter by clicking the checkbox in the Current Meter list. Make sure the flow measurement is within the calibration period of your currentmeter.
Measurements
Select a flow measurement by double-clicking on the measurements textbox. The Windowsfile open dialogue will appear, from this dialogue you can select the flow measurement file.
The date of the selected flow measurement will be presented in the Measurement Date Textbox.
After you made your selections press <Execute>. The condensed current metering data and relevant geometric and hydraulic parameters of the river and cross-section as derived from the flow measurements will be stored in the database. This includes (see also Section Edit and Entry):
- date of measurement,
- measurement number,
- gauge zero,
- water level,
- discharge,
- gradient (dh/dt) in case of unsteady flow effects or fall (F) in case of backwater effects,
- width of cross-section at the water surface,
- wetted perimeter,
- cross-sectional area,
- average flow velocity, and
- hydraulic radius.
The results of the calculation are also presented in a report. By pressing <Report> from the functions tab you can analyse these results.
