Abstract

Aim: The aim of the study was to assess the hydraulic performance for surge flow by measuring the advance time, inflow/outflow rates, application efficiency, distribution uniformity and storage efficiency.

Materials and Methods: Three flow rates (2.7,2 and 1.5 l/s) and three  furrow lengths (160,140 and 120 m) were used with three  cycle ratios for surge flow (0.33,0.5 and 0.75).

Results: The higher application efficiency (78.47%) was obtained at cycle ratio 0.75 and furrow length 120 m with a 2.7 L/S flow rate. Water losses in this study by surface runoff were more pronounced in cycle ratio 0.33. While the highest distribution uniformity (82.07%) was obtained at cycle ratio 0.75 and furrow length 140 m were 1.5 l/s. The highest storage efficiency obtained at cycle ratio 0.75 and furrow length 160 m with a 2 L/S flow rate.

Conclusion: It was concluded that it is possible to adopt a furrow length of 120 m and cycle ratio of 0.75 with a flow rate of 2.7 l/s in clay soil conditions.
