The very low sensitivity of Ea(qo) over a wide range of qo,
when inflow cutoff occurs during the advance phase, is a
desirable property because errors in flow measurements or
non-uniform distribution of inlet flow rate across the border
can have minimal impact on the reliability of design and
management prescriptions. In general, whenever it is feasible, and when near-optimum management scenarios are
achievable, border design and management can preferably be
based on distance-based cutoff criterion (i.e., advance-phase
inflow cutoff option). However, advance-phase inflow cutoff
is feasible only if the combination of system parameters and
variables is such that the crop root zone reservoir can be
replenished to the extent desired (say Zmin = Zr), even when
inflow cutoff occurs prior to, or at, the completion of
advance
