included in the calculations, and the names of input data files to be read by the model. The <br />incidental losses reflect non -crop consumptive use incidental to irrigation, as termed by the <br />USBR CU and Losses Report documentation. If incidental losses are not considered, a zero must <br />be entered for the incidental loss factor. <br />The GUI provides a means to define scenarios. It guides the user through browsing for input <br />files, setting the study period, and specifying the incidental loss factor. The user can then save <br />the scenario information to a response file (.res). <br />2.1.3 CU and Losses Report <br />When generating the CU and Losses Report for the Colorado River basins, the calculations are <br />based on information in the CU and Losses report response file ( *.rcl). The response file <br />provides the model parameters including the reporting period, the percent of incidental losses <br />to be included in the calculations, and the file path of the folders containing the input files to be <br />read by the model. The incidental losses reflect non -crop consumptive use incidental to <br />irrigation, as termed by the USBR CU and Losses Report documentation. If incidental losses are <br />not considered, a zero must be entered for the incidental loss factor. <br />Note that all of the input files associated with each basin need to reside together in a single <br />folder. This folder convention allows the user to only have to specify five file paths (one for <br />each basin) rather than having to separately specify 55 input files. Within each basin directory, <br />the 11 input files must meet strict file naming conventions (see Figure 1). <br />The GUI provides a means to define scenarios. It guides the user through browsing for input file <br />paths, setting the study period and incidental loss factor. The user can then save the scenario <br />information to a response file (.rcl). <br />The first two characters of each file name represents the basin: <br />cm = Upper Colorado River Fusin ym = Yampa River Basin <br />gm = Gunnison River Basin sj = San Juan River and Dolores River Basins <br />wm = White River Basin <br />The next 2 <br />- 6 characters represent the data type_ <br />IWR = <br />Irrigation Water Requirement <br />MINERL <br />= Mineral Use <br />CROPCU = <br />Supply - limited Crop Consumptive Use <br />THERM <br />=Thermal Use <br />CROPAC = <br />Crop ,Acreage <br />MUNICU <br />= Gather Municipal and Industrial Uses <br />LIVSTK = <br />Livestock Consumptive Use <br />EXPIN <br />= Exports Inside the System <br />STKEV = <br />Stockpond Evaporation <br />EXPOUT <br />= Exports Outside the System <br />RESEV = <br />Reservoir Evaporation <br />3.
