| Abstract: | A complete set of dependent furrow irrigation variables has been identified, for which empirical functions, of general applicability,
have been developed. A one-dimensional sensitivity analysis technique coupled with dimensional analysis was employed to reduce
the number of independent irrigation variables to a manageable size. Simulation experiments were carried out to generate the
data used in developing the pertinent functional relationships. Regression analysis was used to ascertain the specific form
of the equations. The predictive quality of the functions has been assessed by comparing their output with those of a zero-inertia
model, and was found to be satisfactory.
