• For a given structure, simulates one or more return flow patterns returning to one or more <br />stream nodes to represent the impact of surface and ground water returns on the stream <br />system. <br />• Simulates Transmountain imports and diversions from a basin. <br />• Uses an efficient, direct solution algorithm, which recognizes the impact of a diversion's <br />return flows during the current time step without having to iterate. <br />• Estimates a base or natural streamflow from gaged or estimated streamflow, diversion, and <br />reservoir data. <br />• Performs extensive input data checking. <br />• Provides extensive output reporting capabilities. <br />• Operates on both a PC and a workstation. <br />• Is available to the public and maintained by the State of Colorado. <br />The White Model is operated on a monthly time step from water years 1975 to 1991. It was <br />developed in two steps as follows: <br />1. Phase II, completed in October 1996, explicitly modeled approximately 18,700 acres of <br />irrigated land, 88 key diversions, 2 reservoirs and 6 instream flow reaches. Key structures <br />were identified using the following approach: <br />• A list of diversion structures, based on the structure's net absolute decreed amounts, <br />was compiled and ranked form largest to smallest. <br />• The list was shortened by including those structures that represent 75 percent of the <br />basin's net absolute decreed amounts. <br />Meetings were held with division and district engineers in the basin and the <br />preliminary list of structures was refined to include structures that were considered <br />important by the district engineers. Also, some structures were removed from the <br />model because they historically diverted significantly less than the decree amount, or <br />they were abandoned. <br />2. Phase IIIa enhanced the previous model to account for 100 percent of the basin's <br />consumptive use. This was accomplished using the following procedure: <br />• Sixteen (16) aggregated irrigation structures were added to represent the remaining <br />irrigated lands, which were not explicitly modeled in Phase II (approximately 6,400 <br />acres). <br />• Two (2) aggregated reservoirs were added to represent the remaining decreed <br />storage not explicitly modeled in Phase II (approximately 4,200 ac-ft). <br />Model Development 3-2 <br />
