Abstract: A recirculating furrow infiltrometer was used to simulate surge flow irrigation for various cycle times and cycle ratios. The data collected was used to evaluate two empirical surge flow infiltration models. The effects of furrow geometry, surface depression storage, and recession time were considered. Data collected from a sandy loam field were used to evaluate the infiltration models. The results indicated that a simple model based on the Kostiakov equation worked well in predicting infiltration during surge flow.
