Mass balance output file (.mass)

This is a tabular text file in which each line is written at the interval specified by the item massint in the .par file. Each line has 12 columns that contain the following information:

• Column 1. Time The time in seconds at which the data was saved
• Column 2. Tstep Time step specified in seconds, either by the user or automatically selected
• Column 3. MinTstep Minimum time step used so far during the simulation in seconds
• Column 4. NumTsteps Number of time steps since the start of the simulation
• Column 5. Area Area inundated in square metre
• Column 6. Vol Volume of water in the domain in cubic metre
• Column 7. Qin Inflow discharge in cubic metre per second (from the open domain edges)
• Column 8. Hds Water depth at the downstream exit of the model domain in metre
• Column 9. Qout Calculated outflow discharge at the downstream exit of the model domain in cubic metre per second
• Column 10. Qerror Volume error per second in cubic metre per second
• Column 11. Verror Volume error per mass interval (massint variable in the .par file) in cubic metre
• Column 12. Rain-(Inf+Evap) Cumulative effect of infiltration, evaporation and rainfall over the simulation in 1000 cubic metres (not active in 2D simulations)
