<br />MAY-31-94 TUE 15:53 <br /> <br />P.13 <br /> <br />" "1..... ~ <br />nl1.l';;('i <br /> <br />Task 1.14 . Consumptive Use Model <br /> <br />Introduction <br /> <br />1. Objectives <br /> <br />. Develop IIIld implement a consumptive use model for the Colorado River by <br />using the Gunnison River basin as a prolOlype. ThiB consumptive use model will , <br />compute the amount of water use or depletion due to human activities, See Task <br />Memoranda 1.14-1 through 1.14-5 for a discussion of the evaluation of <br />consumptive use models in Phillie I. <br /> <br />. Implement some of the recommendations for appropriate changes to the USBR <br />methods manual for application in the Stale of Colorado (see Appendi1 C). <br /> <br />. Maintain the SanJI' categories of willer consumption as the USBR's "Colorado <br />River System Consumptive Uses and Losses Report: which is produced evel:}' <br />five years. The CRDSS consumptive use model will be able to verify one year <br />of the 1985 USBR report for the Gunnison River basin, The USBR methods will <br />be included to allow a reasonable replication of the USBR values. although <br />alternative CROSS methods for estimating consumptive use might differ from <br />the USBR methods (see Appendix C). <br /> <br />. Develop and link the consumptive model to the CROSS INPORMIX and <br />GRASS databases through a DMI. <br /> <br />. Implement the system with a graphical user interface. The user will have the <br />abJUty to evaluate baseline scenario (USBR values) as well as create alternative <br />scenarios by modifying the baseline. <br /> <br />2. Assumotions <br /> <br />r <br /> <br />. None of the crop consumptive use models evaluated in Phase I contained a GIS <br />compollcnt. The CRDSS consumptive use model will incOlJXIrate OIS <br />technology for processing spatial data for consumptive use estimations, <br /> <br />. The organization of the consumptive 1180 model will be a central program with a <br />number of module. for computing differenl consumpt.i Ve use categories. <br /> <br />. Portions of the source code for the program developed as part of the project <br />"Reference Crop Evapotranspiration Maps for Colorado," which was joinlly <br />sponsored by the Colorado Water Resources Research Institute and the State <br />Bnginccl's Oroce. will be I1sed in the development of tbe OUl and the <br />manipulation of splllial data for this task. <br /> <br />;.zlS 01.10.H 1-44 <br />
