<br />GJ' ~..:I' <br />- - .. [) <br /> <br />. <br /> <br />net streamflow depletion - the sum of the historic depletions and the 1978 level <br />depletions for a particular year. <br /> <br />node basin - a delineated hydrologic area that is drained by a river system; a subset <br />of an accounting unit. <br /> <br />node basin number - a six-digit number used to identify the 93 node basins that make <br />up the Missouri River basin drainage, created from the accounting unit number. <br /> <br />node basin outflow point - the locations <br />depletions and depleted flows are summarized. <br />based upon four primary criteria: <br /> <br />throughout the Missouri basin at which <br />Ninety-three such nodes were selected <br /> <br />a. U.S. Water Resources Council accounting unit outflow points; <br />b. 5ta te boundaries; <br />c. Mouth of a major stream; and <br />d. Major reservoir outflow point (conservation storage exceeding <br />200,000 acre-feet) <br /> <br />nonbeneficial consumptive use - consumptive use of water without any resulting direct <br />economic benefit to man. An example is the use of water by riparian vegetation. <br /> <br />on-farm efficiency - the volume of water stored in the soil root zone and used by <br />the crop, expressed as a ratio or percentage of the volume of water delivered to the <br />farm. On-farm efficiency characterizes both the on-farm distribution system and the <br />field application systems. <br /> <br />. <br /> <br />output - the process of receiving data or information out of a data processing <br />system. <br /> <br />partial cut - a type of timber harvest in which only selected trees within the timber <br />sale boundary are cut. <br /> <br />partial service irrigation - that type of irrigation in which the entire crop irrigation <br />requirement is not available beyond a certain point in the growing season. A cutoff <br />date of July 15th was used in the hydrology study for the upper basin states (MT, <br />WY, ND, 5D). In the lower basin states (NE, lA, K5, MO, MN, CO), one-half of the <br />monthly crop irrigation requirement was provided for the irrigation season. <br /> <br />ercent ossible sunshine - the total time during which bright sunshine is received in <br />a specified per iod monthly for this study) expressed as a percentage of the total <br />time during which bright sunshine is possible. The possible length of time varies with <br />latitude at any given date and with the date at a given latitude. <br /> <br />range pitting - a mechanical grazing land treatment for the purpose of reducing <br />surface runoff. <br /> <br />regeneration - a term relating to the regrowth of forest vegetation following timber <br />harvest or other disturbance. <br /> <br />. <br /> <br />remote sensing - collection of information <br />from a distance without physical contact. <br />sa tellite-borne sensor systems. <br /> <br />or data about certain objects or conditions <br />Examples are aerial photography and <br /> <br />1-11 <br />
