    Using gauge station data in a model

    Access and use real-time data from national river gauge stations.

    See an example by watching this step-by-step tutorial video, or find out more in the quick look-up guide below.

    1. In the Hydrology+ tab, click the View River Stations dropdown, and select a gauge type from the list provided.
    2. Click the station of interest on the map. A label will be displayed with the name of the station. Click View full info in the bottom left of the label to open the gauge station.
      If selecting a gauge does not display a label, click Settings in the top left of the Hydrology+ tab and ensure the second checkbox Show summary gauge information when selecting a gauge is checked on. Click Apply and then OK to save these changes.
    3. Within the gauge station, click on the second tab to view Observed Data.
    4. The buttons provided in the top toolbar allow for easy navigation of this data. Additionally, you can click on the plot at a starting point and drag the mouse over the plot, then release at an ending point. This will zoom in on the highlighted data; changing the range to be from your selected start point to your selected end point. 
    5. When viewing 8 weeks of data or less, the Export Boundary button becomes available in the top right. 
    6. Click the Export Boundary button to open a new window. Here you can make further adjustments, and select the export format.
      A flow-time (QT) boundary will export in event file (.ied) format, ready to use in your river networks. The software will automatically adjust this to a head-time (HT) boundary if viewing level rather than flow. Alternative options are to export as a .csv, which could then be used as input over a 2D domain, or as a .cal file, most suited for calibration.
    7. When satisfied with your selections, click the Export button in the bottom right corner. This will open a standard File Explorer window for you to select a save location for your file. Once saved, a pop-up will confirm the export has completed successfully.
    8. Use your exported files within your models.

    Using FEH data within your hydrology database

    Enhance your FEH and ReFH2 modelling using your hydrology database.

    Import downloaded FEH catchment descriptors, then access this data in all future sessions.

    Importing FEH catchment data

    • Import your data once, and then use it in all future projects.
    • Access the portal through the Download button.
    • Import the data using the Import button. You can import single catchment data by clicking the Add file... button, or simply drag and drop the file into the field provided. You can also import batches with the Add batch... button.
      Both single catchments and batches of catchments should be imported in the format they are downloaded from the portal. In the case of a batch, this is a zipped folder. In the case of single catchments, you should browse to the .xml file, and the boundary shapefiles (if relevant) must be located in the same folder as this .xml. 

    Using FEH catchment data

    • Once imported, you can view catchments in the map using the View FEH catchments button. Click this button again to hide the catchments.
      To load the catchment descriptors from the map, right-click the catchment and select View catchment descriptor information. Imported catchments can be also be deleted from this right-click menu.
    • Imported FEH catchment descriptors can also be viewed in a table. Click the FEH Tabular view button to open this table.
      To load the catchment descriptors from the tabular view, either double-click the row in the table, or right-click the catchment and select View catchment descriptor info. Imported catchments can be also be deleted from this right-click menu.
    • An Export button is available to export the catchment descriptors to .xml format, ready for use in your models.
