The user will have previously specified that the MODSIM network model will be modified to <br />? <br />include a new node or to delete an existing node . MODSIM will provide a warning instructing the <br />user to recalculate the natural inflow for the immediate downstream node. <br />nodeflow <br />All low level DMIs will be developed under Task 1.05 (Systems Integration). The DMI utility <br />will be developed under Task 1.15 (Water Right s Planning). <br />nodeflow <br />The DMI utility will be run from the command line by speci fying the program name, input file, <br />and output file. The command line syntax is shown below: <br />nodeflow <basin>.NCT <basin>.INF <br />The DMI utility requires as input an ASCII text control f ile, <basin>.NCT. The input file will include user- <br />specified information for all inflow nodes within the river basin being modeled. The following information <br />is included for each inflow node: <br />The user will specify the output units of monthl y natural streamflow in acre-feet or hectare- <br />? <br />meters. The default output units will be acre-feet. The output units must be consistent with the <br />units of the CRDSS core stati on natural streamflow data. <br /> <br />By specifying order numbers, the user will be able to identify the model nodes of interest for the <br />? <br />following items: <br />-Location of the model inflow node for wh ich natural streamflow and inflows will be <br />estimated. <br />-Location of the immediate upstream inflow nodes that have prior estimates of natural <br />streamflow (this include s nodes on tributaries). <br />-Location of CRDSS core stations that will be used for estimating natural streamflow at the <br />model node of interest. The CRDSS core stations selected by the user should be <br />representative of the hydrogeologic character istics for the basin containing the node of <br />interest. A minimum of two CRDSS co re stations should be selected. <br />The user will specify the tributary drainage ar ea and the mean basin elevation for the model node <br />? <br />selected previously. Additionally, the user will specify the tributary dr ainage area and the mean <br />basin elevation for each CRDSS core station selected previousl y. The water rights planning group <br />will make estimates of drainage areas and mean ba sin elevations for all CRDSS core stations and <br />model inflow nodes as part of the initial setup of the MODSIM network. <br />In order to distribute the estimated average a nnual natural streamflow at the inflow node of <br />? <br />interest into monthly values, the user will speci fy which CRDSS core station selected previously <br />will be used for the monthly distribution. On ly one CRDSS core station can be selected. <br />The required format of the ASCII text input control file is shown below in Table 1. <br />2 <br />A275 01.09.95 1.15-16 Hyre, Fosha <br />
