Beginning and Ending Dates of the Growing Season <br />Beginning and ending dates of the growing season are used to determine the default dates of a crop's <br />growing season. Unless they are earlier than the earliest moisture use or later than the latest moisture <br />use, these dates are used to define the growing season duration. These data are needed to operate the <br />consumptive use model and may be obtained from the SCS and ASCE manual Evapotranspiration and <br />Irrigation Water Requirements. The database entity that will hold these data is the <br />crop_character <br />entity. <br />Mean Air Temperatures of Earliest and Latest Moisture Use <br />Mean air temperatures of earliest and latest moisture use are temperatures defining the growing season of <br />a crop. The earliest moisture use would take place during the first planting of the crop, and the latest <br />moisture use would take place during the last harvest of the crop. This temperature is basically a <br />measure of how sensitive the plants are to frosts during the beginning and the end of the growing season. <br />These data are needed to operate of the consumptive use model and may be obtained from the SCS and <br />ASCE manual Evapotranspiration and Irrigation Water Requirements . The database entity that will <br />hold these data is the entity. <br />crop_character <br />Soil Characteristics <br />Soil characteristics are needed to describe how water moves through a specific soil and the soil's capacity <br />to store water. These characteristics are estimated from basic soil information, such as soil type and <br />depth. These data are needed to operate the consumptive use model and may be obtained from the SCS. <br />The database entity that will hold these data is the entity. <br />soil_coeff <br />Stock Ponds Characteristics <br />Stock ponds characteristics are a table of values that will be used to compute stock pond evaporation. <br />The most probable source for these data is the State. These data are needed to operate the consumptive <br />use model. These data are derived from a formula that computes a surface area, given a known volume. <br />The database entity that will hold these data is the entity. <br />Non_Jurisdictional_dam <br />Livestock Consumptive Use Characteristics <br />Livestock consumptive use characteristics are a table of values that describe the volume of water <br />consumed by three types of livestock (cows, sheep, and hogs). These data are needed to operate the <br />consumptive use model and may be obtained from technical publications (e.g., Great Plains Beef Cow- <br />Calf Handbook ). The database entity that will hold these data is the entity. <br />creature_coeff <br />Human Consumptive Use Characteristics <br />Human consumptive use characteristics are a table of values that describe the volume of water consumed <br />by humans. These data are needed to operate the consumptive use model and are available from <br />technical publications. The database entity that will hold these data is the entity. <br />creature_coeff <br />2 <br />A275 01.08.95 1.07-1 IDS Group <br />
