Zero-Inertia Surge Model with Wet-Dry Advance
ABSTRACT Azero-inertia model for surge flow furrow irrigation was developed from a non-linear continuous flow model. Non-linearity of the governing equations allowed simultaneous modeling of wet and dry sections of furrow. Time step was adjusted at the wet-dry interface. Unique furrow geometry and roughnesses were assigned for wet and dry furrow stretches. The surge model was tested against three sets of field data from Davis (California), Flowell (Utah), and Kimberly (Idaho) and a limited sensitivity analysis was performed.
