<br />Glossary of Terms <br /> <br />. <br /> <br />Numerous technical terms or terms unique to this subject are used in discussing <br />the Water Accounting System, Some have a variety of meanings or interpretations, <br />even among water resource experts. The following definitions will be used <br />consistently throughout this manual. <br /> <br />accounting unit - an area that is drained by a river system, a reach of a river and <br />its tributaries in that reach, a closed basin, or a group of streams forming a coastal <br />drainage, as defined by the U.S. Water Resources Council. <br /> <br />aquifer - a formation, group of formations, or a part of a formation that contains <br />sufficient saturated permeable material to yield significant quantities of water to <br />wells and springs. <br /> <br />batch processing - a method of processing a quantity of data in one operation. <br /> <br />cathode ray tube (CRT) - a vacuum tube (television screen) sometimes used to display <br />output from a computer system. <br /> <br />CIR adjustment factor - an adjustment in the crop irrigation requirement made for <br />drier than normal years, since surface water is generally limited in dry years. The <br />adjustment factor was used to reduce estimated irrigation depletions. <br /> <br />clear cut - a type of timber harvest in which all trees within the timber sale <br />boundary are cut. <br /> <br />. <br /> <br />computer - an electronic machine for performing calculations or logic operations. <br /> <br />computer program - instructions written in such a manner that they can be <br />interpreted by a computer. <br /> <br />computer system - computer equipment (hardware) and computer programs (software) <br />that are used together for input, processing, storage and output of information. <br /> <br />consumptive water use - a use of water in which the return flow available following <br />use is less than the amount of water supplied for use. Water is lost to the system <br />through evaporation, transpiration, or metabolic processes. <br /> <br />contour farming - farming sloping land in such a way that plowing, preparing land, <br />planting, and cultivating are done along the contour, not across it. <br /> <br />conveyance efficiency - the volume of water delivered to the farm, expressed as a <br />ratio or percentage of the volume of water diverted from a stream or other water <br />supply. Conveyance losses may include evapQration, seepage, or leakage. <br /> <br />crop distribution pattern - the proportional pattern, by area, of the irrigated crops <br />which comprise the total amount of irrigated land in a node basin. A constant crop <br />distribution pattern, based on 1978 conditions, was used throughout the entire study <br />per iod. <br /> <br />. <br /> <br />crop irrigation requirement - the additional amount of water, supplied by irrigation, <br />needed to supplement the effective precipitation to adequately grow a given crop to <br />maturity. <br /> <br />1-8 <br />
