Specific Yield <br />The amount of water that rock or soil, after being saturated, will yield when drained by gravity, <br />expressed as a ratio or as a percentage of the volume of the rock or soil. (Rice (1991)) <br />SQL -Structured Query Language <br />The language that is widely recognized as the standard for database queries. The standard addresses <br />the syntax of conditional statements which define search criteria. <br />Staff Gage <br />A graduated scale used to indicate the height of the water surface in a stream channel, reservoir) lake, <br />or other water body. (Rice (1991)) <br />Stage <br />The height of a water surface above an established datum (see gage height) (Rice (1991)) <br />State Engineer <br />The chief executive officer in the executive department of the state government who administers water <br />rights. (Rice (1991)) <br />See also division engineer. <br />Stochastic Flow Model <br />The model used to perform statistical analyses of historical flow to generate short- and long-term flow <br />predictions. <br />Storage Right <br />A right defined in terms of the volume of the water which may be diverted from the flow of the stream <br />and stored in a reservoir or lake to be released and used at a later time either within the same year or <br />a subsequent year. (Rice (1991)) <br />Substantive Law <br />The law defining rights to the use of water. (Rice (1991)) <br />Time Series <br />A set of data consisting of a time-stamp and a value. In general, the time-stamps are equally spaced <br />(e.g., daily, monthly, yearly data). <br />Tolerance <br />An (relatively) small value that is acceptable as error when performing a simulation or other analysis. A <br />tolerance value may be absolute (e.g., 10 acre-feet) or relative (e.g., 1 % difference between the <br />simulated and historical run). A higher tolerance results in a more accurate calibration but requires <br />more time to perform the calibration. <br />Total Consumptive Use <br />The amount of water, regardless of its source, used by the crops during the growing season. It is the <br />amount of water that is physically removed from the stream's system and is not available for other <br />users on the stream. (Rice (1991)) <br />Trans-Basin Diversion <br />The removal of water of a natural stream from its natural basin into the natural basin of another <br />stream. (Rice (1991)) <br />Transfer <br />The process of moving a water right originally decreed to one ditch, to another ditch or point of <br />diversion, by court decree. A transferred water right generally retains its priority in the stream system <br />and may or may not retain its right to divert its entire decreed amount. (Rice (1991)) <br />Transient <br />Conditions which are changing with time. (Rice (1991)) <br />Transpiration <br />The process of transpiring. Plants transpire water vapor containing waste products from the process of <br />photosynthesis through skin pores (called the stomata plant tissue). <br />Tributary Drainage <br />The area from which water drains by gravity into a water course. (Rice (1991)) <br />Unit Consumptive Use (Irrigation) <br />The amount of water used by crops for growth, less effective precipitation, expressed in terms of acre- <br />feet per acre or feet of water. Unit consumptive use is considered synonymous with irrigation <br />
