Many erosion studies have been conducted using water drops formed by sprinkler irrigation nozzles. Rainfall intensity is controlled by varying the on‐off time. This study shows that after a certain point, the energy to initiate runoff is increased as the nozzle off time is increased. Water intake rate is increased as application rate is increased even though runoff is taking place.
