Sediment tracing
Implemented by Jun Xie - as published in https://www.sciencedirect.com/science/article/pii/S0341816222004817
Details of the implementation and how to use this can be found here: https://zenodo.org/record/8138206
Water tracing
Created and coded by Matt Wilson as published in https://gmd.copernicus.org/articles/16/2415/2023/gmd-16-2415-2023.html

The additional GUI components for water source tracing are as follows:
Enable water source tracing in the Hydrology tab, with the checkbox under the reach input variables. Note that each source file specified will be counted as one source, even if it is used in multiple grid cells. If you are using rainfall as an input, you can also provide a rainfall zonation map to split the tracing of rainfall depending on where it falls (e.g. in different catchments).
Under Save Options, optionally place a check next to the water tracers and rain zone tracers outputs. Set up the rest of the model in the same way as any other simulation, then load data and press Start.
To visualise the water sources during a simulation: an extra water tracer visualisation control box is added to the GUI. To view the fraction of depth from each source, assign numbers to each of the red (R), green (G) and blue (B) colour options. Note that sources 1 and 2 are reserved for downstream stage and rainfall, so the fluvial sources begins at 3 and increases in the order specified in the reach input variables. The enhance slider control changes the value of beta used for emphasising lower water source fractions (see equations 11 and 12 in Wilson & Coulthard).
The point info window checkbox opens an extra dialog which allows a user to click on the map and obtain information about depth, flow velocity etc. The fraction of each water source in the cell is included in this dialog - not that the total water source tracer should sum to 1.0: very small deviations from this are possible due to numerical errors.
Getting started: run the software and open (using Config File > Open) either the Carlisle 15 m case study (carlisle15m load file.xml). These are all set up and you should be able to click load data then Start.
Major changes in addition to those mentioned before:
- Solute tracer added:
o Solutes loaded from hydro input files (columns 15 +), any units of concentration. The same column in each input file will refer to the same solute (although it might be useful to add a header line to ID them instead).
o Routing based on depth weighted averaging, similar to water source tracing but with concentrations instead of proportions.
o Visualisation for these added to the interface.
- Point info window updated to include the various water tracers, when activated
additional features
- A control for the directory to save outputs has been added to the files tab, and a bit of adjustment to the layout to fit that in; options also included in the xml. The check box there is quite useful – it will lead to the creation of a folder with the date-time of the time simulation to save the outputs.
- Spatially variable roughness
