Problem 11.6: The following crops will be cultivated with the indicated areal percentages; cotton (30%), corn (30%), and wheat (40%). The area lies at 36°N latitude. No precipitation is observed in July. Maximum water table elevation is 1.2 m below the ground surface after each irrigation. The minimum readily available moisture in the root zone is estimated to be 60 mm. Taking D=9 m, t=20°C, determine the value of L. Assume that wheat has the same crop coefficient as corn. Take K=1 m/day, u=0.10, d-2 m, h=0.4 m, ro-0.1 m. Answer: L-66 m

During a particular stage of the growth of a crop, consumptive use of water is 2.5 mm/day. Determine the interval in days between irrigations, and the depth of water to be applied when the amount of water available in the soil is 50% of the maximum depth of available water in the root zone, which is 80 mm. Assume irrigation efficiency to be 60%.

Q#2 The moisture holding capacity of the soil in a 100-hectare farm is 18 cm/m, the field is to be irrigated when 50% of t'ne available moisture in the root zone is depleted. The irrigation water is to be supplied by a pump working for 10 hours a day, and water application efficiency is 75%. Details of crops planned for cultivation area are as follows: Root z'one depth (m) Peak rate of moisture use (mm/day) 5 4 Crop X Y Solve for 1) The capacity of irrigation system required, to irrigate crop X in 36 hectares. 2) The area of crop Y that can be irrigated when the available capacity of irrigation is 40 L/s. 1 0.8
There is a reservoir covering a 500-hectare area that has a constant draft of water pumped from it. The reservoir has a constant inflow from an upstream watershed, where the annual rainfall is 550 mm and the annual runoff is 312 mm. Over a 30-day period, the reservoir depth drops 9.5 m. During this time, there was precipitation over the reservoir of 87 mm and the total evaporation was 73 mm. What is the daily draft of water from the reservoir (in hectare-meters)?
Crops are grown in a field having soil, which has field capacity of 30% and permanent wilting point of 13%. The effective depth of root zone is 80 cm. Irrigation water is supplied when the average soil moisture drops to 20%. Consider density of the soil as 1500 kg/m³ and density of water as 1000 kg/m³. If the daily consumptive use of water for the crops is 2 mm, the frequency of irrigating the crops (in days), is
