Reservoirs <br />The model calculates reservoir consumptive use for each spatial identifier using the surface area and a <br />fullness factor, based on elevation, for each reservoir. For reservoirs with an elevation <= 8600 feet the <br />fullness factor defaults to 0.75. For reservoirs with an elevation > 8600 feet the fullness factor defaults <br />to 0.87. The model computes evaporation and precipitation for each reservoir using weighted climate <br />data for the specified area (the union of the spatial identifiers). These data are found in the climate files <br />(?.wbc? or ?.wpm? as a suffix). <br />Municipal <br />The model calculates municipal consumptive use for each spatial identifier using the total population, <br />gross daily consumption per capita, and actual percent of consumption for each municipal area. The <br />urban population is calculated by multiplying the total population by a percentage that represents the <br />urban population. The rural population is the difference between total population and urban population. <br />The total population is also given a monthly coefficient, allowing the model to adjust for variations in <br />population and water usage throughout the year. Approximate consumption for commercial uses and for <br />public uses is calculated by the model based on the total population of the municipal area. <br />Mineral Resources <br />For each spatial identifier, the model uses the actual monthly consumption rate (not a calculated value) <br />due to mineral resources. <br />Thermal Electric Power <br />For each spatial identifier, the model uses the actual monthly consumption rate (not a calculated value) <br />due to thermal electric power. <br />Exports <br />For each spatial identifier, the model uses the actual monthly export rate (not a calculated value) for each <br />export site. <br />cunonet DMI Inputs <br />The DMI is passed the name of a control file defining the area and time parameters selected by the user. <br />This file is read by the DMI as it builds the low-level DMI input data structure. Control files have ?.ctl? <br />as a suffix. The file format is attached. <br />Area and Time Parameters <br />Number of spatial identifiers describing the specified area <br />? <br /> <br />A string defining the unit of the spatial identifier list (county, water district, hydrologic unit, <br />? <br />and river basin) <br /> <br />List of spatial identifiers describing the specified area (county name, water district number, <br />? <br />hydrologic unit number, or river basin name) <br />2 <br />A275.01.09.95 1.14-13 CSU IDS <br />
