TUFLOW CATCH Tutorial M01 Results QGIS: Difference between revisions

<li> Salinity and dissolved oxygen are constant pollutants. As such, their corresponding output values should be constant throughout the simulation. <br>

<br>

<br>

<li> Alive and dead E. coli have been defined with the same pollutant export parameters, so their outputs should be the same. <br>

<br>

<br>

<li>Temperature has been provided as a timeseries with four input data points ('''temperature.csv'''). TUFLOW CATCH has interpolated these to produce temperatures at each timestep in the output timeseries file.<br>

<br>

<br>

<li> When plotting flow against pollutant concentrations, a noticeable spike appears once the dry store release threshold is reached, followed by a gradual decline for the remainder of the simulation. <br>

<br>

<br>

'''Note:''' The pathogen concentrations are plotted on a logarithmic scale.

<li> In Windows File Explorer, navigate to the '''TUFLOWCATCH\bc_dbase''' folder and open '''TC01_001_catchment_hydraulic_mass_balance.csv'''.

<li> This file contains the total surface and groundwater flow (m³) and associated pollutant masses leaving the TUFLOW HPC model and entering the receiving polygon ('''2d_rp_TC01_001_R'''). Outputs are written at the same interval as '''TC01_001_catchment_hydraulic_receiving.csv'''.<br>
