The cunonet DMI generates a formatted data file required by the non-irrigation components of the CU <br />model. Files having ?.oth? as a suffix, contain general information about non-irrigation components. <br />2.0 DISCUSSION/ANALYSIS <br />The function of this DMI is to return formatted data on non-irrigation consumptive uses within the <br />specified sub-area and time period. This includes the following categories: livestock use, evaporation <br />from stockponds, evaporation from reservoirs, municipal use, industrial use, and exports. The file <br />assumes the availability of information found in the climate files (?.wbc? or ?.wpm? as a suffix). <br />2.1 Data Categories for Other Uses <br />This section will describe in general terms the type of data returned for each non-irrigation category <br />using the cunonet DMI. The data sources and types are described in detail for each sub-area in Task <br />Memoranda 2.09-10, 2.09-11, 2.09-12, and 2.09-13. <br />Livestock <br />The model uses livestock consumptive use data, for each sub-area. These data consist of monthly head <br />counts and a default daily consumption amount for cattle, hogs, and sheep. This default value is given in <br />gallons per head per day and is the same for the entire Western Slope. The user has the option of <br />changing these default values in the Edit Scenario Window in the CU Model Interface. <br />Stockponds <br />The CU Model calculates stockpond consumptive use for two aggregates in each sub-area. These <br />aggregates are based on elevation. Two volumes are returned for each sub-area, one for each aggregate. <br />The low level DMI returns the total volume of stockponds with elevation <= 7750 ft and the total volume <br />of ponds with elevation > 7750 ft. The CU Model converts the total volumes to approximate surface sub- <br />areas and then applies a fullness factor based on the elevation category above. For stockponds with an <br />elevation <= 7750 ft, the fullness factor defaults to 0.75. For stockponds with an elevation > 7750 ft, the <br />fullness factor defaults to 0.87. This fullness factor can be changed by the user in the Edit Scenario <br />Window of the CU Model Window. The model computes evaporation and precipitation for each surface <br />sub-area using weighted climate data for the specified sub-area (the union of the sub-areas). These data <br />are found in the climate files (?.wbc? or ?.wpm? as a suffix). <br />Reservoirs <br />For reservoirs with an elevation <= 7750 ft, the fullness factor defaults to 0.75. For reservoirs with an <br />elevation > 7750 ft, the fullness factor defaults to 0.87. This fullness factor can be changed by the user in <br />the Edit Scenario Window of the CU Model Window. The model computes evaporation and precipitation <br />for each sub-area using weighted climate data for the specified sub-area. Surface areas are unavailable <br />from the database for individual reservoirs, therefore evaporation amounts can be directly entered for <br />reservoirs. <br />Municipal <br />The cunonet DMI returns a monthly population amount. The model calculates municipal consumptive <br />use, for each sub-area, using the total population (Census data for 1990), gross daily consumption per <br />capita and actual percent of consumption for each municipal sub-area. The urban population is calculated <br />2 <br />11.29.96 2-09-19 IDS/CSU <br />
