A Simplified Design Procedure to Determine the Wetted Radius for a Trickle Emitter
ABSTRACT Dasberg and Bresler's (1985) method for predicting the wetted radius from a point source emitter was simplified so that soil texture, emitter flow rate, and soil water depletion potential were the only inputs required. Field tests in a peach orchard, on a sandy loam soil, at two emitter flow rates showed that predicted wetted radius values were within 11% and —19% of measured values.
