<br />. <br /> <br />. <br /> <br />002315 <br /> <br />3 <br /> <br />II. Implement and DOCUITIc:mt a Hydrologic Screening Model for the UCRB Using an <br />Existing Hydrologic ~Iodel Which can Easily be Set Up ami i-Iodified. <br /> <br />During the month of July, work on the fIYDR{ilSS ~Iodel consisteu of setting <br />up data input tables and conducting tests of the moueI. Tables created <br />include flow and stage tables and the model network structure. The network <br />structure table converts the river network node structure (which was <br />presented in last month's progress report) into table format for data entry. <br />The Elm, table \,as cl'cateu to express the hyd rologic reconl for each <br />control point, and was derived from data files produced by the Colorado <br />River System Simulation (CRSS) mouel and USGS gage records. The third <br />table created is the stage or depletiQns table. The stage table contains <br />data on depletions in the basin as well as infonnation on reservoir <br />operations. 111is table also was derived primarily for CRSS files and <br />is subject to verification and refinement as the modeling effort proceeds. <br /> <br />To uate, the model has not been rWl successfully using UCRB data, Problems <br />have been l'ncOlU1teredin increas ing the lliml'l1S ion of IIYDR{ilSS programs to <br />accept dat:! arrays of the size necessary to simulate the operations of the <br />Colorado River. Work will get wlderway in ^ugust to program arowld this <br />limitation of IIYDR{ilSS. <br /> <br />In other (levelopments, the \\1'E TCGlIl has bcen contacted by the State of <br />Wyoming regarding their contracting \,ith the University of Wyoming Water <br />for Fnergy Resource Center to evaluate anu interface with the Water for <br />Energy Project. Mr. Tom Wesche, Research Scientist with the center, has <br />been assigned to the proj ect. ~Ir. Wesche I s efEort \vill be threefold and <br />\vill initially center arowld the following activities. <br /> <br />1. Contacts \vith Wyoming State agencies regarding their knowledge <br />of the model, their input into the clatabase, and their possible <br />future use of such a model. <br /> <br />2. Development of concise descriptions and evaluations of the over- <br />all model and its components (IIYDJ<0SS, PI"\BSr~l, Tcmperature). <br /> <br />3, Assessment, in regard to content, qual i ty, and source, of the <br />Wyoming infonnation currcntly prcscnt in the model's database. <br /> <br />To facilitate cooperation and interaction \vith ~Ir. Tom Wesche, ~1r. Terry <br />Waddle, liydrologist with the Instre~un FJ ml and ^quatic Systems Group at <br />WELlJT, and ~Jr. Bob Green, Hydrologist at the Regional Office of FWS, have <br />been assi!,'ned as contact persons. During the month of .July, telephone <br />contact \1aS made with ~.1r. Wesche. The progress of the Wyoming evaluating <br />study will be reported in future progress reports. <br />
