    Abstract

    In the present program, SWATRE(-xtended) the following types of conditions at the bottorn of the system can be used: - groundwater level; -flux from the saturated zone (prescribed); the groundwater level is computed; - flux from the saturated zone (calculated as the s~m of the flux towards ditches and the flux of deep percolation); the groundwater level is computed; - flux from the saturated zone (calculated with a flux - groundwater level relationship); the groundwater level is computed; - pressure head of bottorn compartment; - zero flux at the bottorn (of an unsaturated soil profile); i. e, when an impermeable layer is present; - free drainage at the bottorn (unit hydraulic gradient; unsaturated soil profile).
