Not all figures are to scale. Assume any values if you need them. Q1/ A farm with dimensions and slopes (50 Marks) = shown in the figure below. If you asked to design a border irrigation system and if you know that Net depth of irrigation - 96mm .Manning coefficient = 0.15, Time of work in the farm is 6 hours/day. Design consumption use of water from the crop (ET) 16 mm/day, Width of the agricultural machine equal to 2.5m, Equation of infiltration - D= 12-05 and Efficiency of irrigation= 60%. You can neglect the recession lag time. Find the width and number of the borders, Irrigation interval and time required to irrigate the whole farm, Depth of flow in the inlet of border Number of borders that irrigated in one day and The neglected recession lag time Slope of irrigation % Maximum border width 0-0.1 30…
