1. Establish the feasible range of L and qo.
1a. Determine the maximum non-erosive unit inlet
flow rate (qmax) and the minimum unit inlet flow
rate required to ensure adequate spread (qmin). Any
appropriate set of equations can be used to
determine qmax and qmin. For example, using the
empirical equations of Hart et al. (1980), qmax
(in L/min/m) for non-sod-forming crops, such as
alfalfa and small grains, is
