Results

A time-varying 1D river simulation will generate default time series outputs at every model node for the following parameters:

• Flow
• Water level (stage)
• Velocity
• Depth
• Froude number
• Unit mode
• Unit state
• Total energy

In addition advanced options are available to produce selected additional output parameters.

1D river simulations create data outputs in a binary format (to reduce file sizes). Flood Modeller provides various tools to extract and review these 1D data.

Flood Modeller provides functionality to Plot a Time Series of your 1D river results. This can display data from multiple nodes in your network, and allows for selection of multiple variables, from multiple outputs. You can animate a Time Series and fully customise a Time Series quickly and easily.

You can Plot a Long Section of your 1D river results to visualise the longitudinal variation in your channel bed, with or without modelled water levels overlaid. It is also possible to animate a Long Section to visualise the data changing over time. Icons provide functionality to customise a Long Section to your specifications.

Flood Modeller provides functionality to Plot a Cross Section of your 1D river. This displays the cross-sectional view of a River Section node, with or without modelled water levels overlaid (from one or multiple model outputs). You can also animate a Cross Section and fully customise a Cross Section with easy-to-use icons provided directly on the plot.

You can Plot an XY Series of your 1D river results to visualise the relationship between selected model variables, for example stage vs. flow. This can display data from multiple nodes in your network, and allows for selection from multiple outputs. You can customise an XY Series chart to your specifications.

From (successfully completed) 1D simulations loaded into the Project panel, the option is now provided to view the 1D diagnostic log file, which will open in the text editor default to your machine.

Other options

Further options for visualising 1D river results could initially involve Creating a TIN (a triangular irregular network). This can be used to Create a Flood Map, to compare ground levels and water levels to determine if an area is flooded. It is also possible to animate a 1D flood map, with even better results obtained via Animation with the 1D flood map tool.

From creating a flood map, you can Use the 3D viewer tool to further visualise and animate flood extents. Additionally or alternatively, the 1D Flood Calculator tool can be used to convert these results into flood depth grids and flood extent shapefiles. These 1D Flood Calculator results can also be used in a New Flood Viewer project.

Further time series outputs can be extracted from your 1D results using the Tabular CSV tool. This can be accessed from the Results tab of the main toolbar. The tool will extract user selected data from the binary format output from your 1D model and write these data to a comma separated text format (file extension csv). This can then be imported into other software for further analysis, e.g. MS Excel or similar spreadsheet tools.
