Soil intake rate data and irrigation advance data were collected on three farms in northeast Colorado during the summer of 1985. These data, and simulated advance data generated with a kinematic wave model, were used to test the adequacy of seven proposed simplified techniques for evaluating surge irrigation. The technique selected consistently results in values of application efficiency and distribution uniformity within three and twenty percent, respectively, of the values given by more complex procedures. This procedure requires determining the time at which water reaches the end of a previously wetted furrow section, the distance of advance at the time inflow stops and the maximum advance distance for each surge. This represents approximately 90% reduction in advance data collection over previous evaluation methods.
