Boundary Cumulative Water Fluxes

Graphs showing distributions versus time of cumulative water fluxes across boundaries having different types of boundary conditions.

Available choices for the independent variable:

Potential Atmospheric flux	A potential flux across the atmospheric boundary; a combination of precipitation, irrigation, or potential evaporation fluxes, potential atmospheric flux = potential evaporation - precipitation
Potential root water uptake	Potential transpiration
Actual Atmospheric flux	An actual flux across the atmospheric boundary; infiltration (negative) or actual evaporation (positive)
Actual root water uptake	Actual transpiration
Variable boundary flux	This information is provided for all four time-variable pressure head/flux boundaries. Note that HYDRUS adds cumulative fluxes across the "Time-Variable Flux 1" and "Time-Variable Head 1" boundaries and reports the resulting value as "Variable Boundary Flux 1". Similarly for "Time-Variable Flux 2" and "Time-Variable Head 2", and so on.
Constant boundary flux	HYDRUS adds cumulative fluxes across both Constant Head and Constant Flux boundaries.
Seepage face flux
Drain boundary flux
Free or Deep drainage boundary flux
Gradient boundary flux
All boundaries	Displays all fluxes
Surface Runoff	Actual surface runoff (difference between precipitation/irrigation and actual infiltration)
Evaporation	Actual evaporation
Infiltration	Actual infiltration

All fluxes are positive out of the domain (except for Infiltration - a variable not displayed in the graph, but listed in the output file CumQ.out).

Units are [L2] for two dimensional applications and [L3] for three dimensional applications.
