Show FLOW OF IRRIGATION WATER Question as to Amount of Water Rs-quired Rs-quired to Irrigate Sixty Acrss In Orejon Is Answered. "Given four second feet of water for three days, 712 hours, Irrigates 60 acres of land. How many Inches of water would it require per acre continuous How for 15 days to furnish the four second feet for the three days. giving a period of 12 days between Irrlga-tlonsT Irrlga-tlonsT Oregon has taken control of the waters of the state and in ad Indicating the witter rights it has asked us. the original approprlators, how much water we require. A corporation cor-poration hns contested our claims and their expert claims that three-eighths of an Inch of water, continuous now. is the solution to the above problem We are skeptical." The above question Is answered by F. II. Kin In the Itural New Yorker In the following statement : Four second feet of water for 72 hours, applied to 60 acres of land would cover It to a depth of 4.76 inches, and Is equal to t.OM.Soo cubic feet. We do not know the value of a legal Inch of water for Oroiym. For California one Inch of wnier in defined de-fined lis equal to one-fiftieth of a second sec-ond foot. Court decision sets It at one fortieth of a second foot for Arizona. Ari-zona. CWa-in specifies "N i miner's inches In one seco'nd Tot. If the Inch is taken at one fort let h of a second foot it would require four times 40, or 160 Inches, flowing continuously three days, or 72 hours, to equal four second feet continuous flow for 72 hours. Three-eighths of a miner's Inch flowing continuously 15 days li only 9.720 cubic feet, or .044 Inch of rainfall on 60 acres, at the California value, and but 12.150 cubic feet or .055 Inch of rainfall on CO acres at the Arizona vnlue. If applied to one acre Instead of to 60 acres the depth of water, expressed as rainfall, would be CO times the values Just given, or 2.67 Inches, where the California Inch is (he standard, and 3.34 Inches if the Arizona value of the Inch Is taken. In other words, three-eighths of a miner's Inch continuous flow for 15 days Is equivalent to 2.67 Inches to 3.34 Indies of rainfall on one acre, where the values of the Inch are those stated. If three-eighths of a miner's inch flowing continuously 15 dsys gives to one- acre the equivalent of 2.67 to 3.34 inches of rainfall, to apply ap-ply the same amount to the acre in three days, continuous flow, would require re-quire five times three-eighths Inch of water, or one and seven-eighths. |
