The CU model will be generating output data. These data may be stored outside the model in Phase <br />II(a), and a consistent process for handling the generation of scenarios should be developed more fully in <br />Phase II(b). <br />Unit Types for Data <br />Types of units will be a major factor in determining the quality and ease of use of the system. There are <br />often different choices of units for any given data field. Sometimes the source of the data will determine <br />the units for data storage, but the user may define how those units are expressed in the interface. <br />Therefore, in this document the unitless quantity names will be used and some standard unit types will be <br />anticipated. <br />TABLE 1 <br />UNIT TYPES <br />UNITLESS STANDARD <br />QUANTITY NAMEMETRIC REPRESENTATION REPRESENTATION <br />Lengthmeters (m)feet (ft) <br />Volumecubic meter (m3)acre-feet (acre-ft) <br />Areahectaresacres <br />Timehour, day, week, month, yearhour, day, week, month, year <br />Dateday/month/yearJulian days <br />o o <br />Temperaturedegrees Celsius ( C)degrees Fahrenheit ( F) <br />Flow (volume/time)cubic meters per second (cms)cubic feet per second (cfs) <br />Velocity (length/time)kilometers per day (kpd)miles per day (mpd) <br />Universal Transverse Latitude and Longitude <br />Location Mercator (UTM) (Lat/Long) <br />Baseline Scenario Data <br />When the user accesses the model, he/she will be presented with information that will be stored as a <br />baseline scenario and will be asked to specify certain parameters needed to estimate consumptive use. <br />These values may be used as default values or altered by user input. Based on the input from the user, <br />the CU Model will use the DMI to extract the required data to be used in estimating consumptive use. <br />TABLE 2 <br />BASELINE SCENARIO DATA <br />CU MODEL INPUTUNIT TYPESTRING TYPEFROM ENTITY(S) <br />Beginning date of CU calculationDateCharacter String or IntegerCU_Scenario (Default) <br />Ending date of CU calculationDateCharacter String or IntegerCU_Scenario (Default) <br />First date of irrigation (each year)DateCharacter String or IntegerCU_Scenario (Default) <br />Last date of irrigation (each year)DateCharacter String or IntegerCU_Scenario (Default) <br />Gunnison basinSpatialCU_Scenario (Default) <br />2 <br />A275 01.09.95 1.14-2 Lange <br />
