The model <br />rcquira 215,000 octal 64-bit words of computer <br />core memory storage. At present a so.year run <br />costs around S20 and requi:ra about 80 seconds <br />of COIIlpUter time. <br /> <br />Applications of Colorado River <br />Simulation System <br /> <br />The ~ was first applied bY the WcstWide . <br />study poup in 1973~ From 1973 to 1978, ~ <br />was given serious scrutiny and many "'"111fl\!!1 <br />were made to solve SOJDe of the problems and <br />strengthen some areas of weakness that bad <br />been detected, In 1978, CRSS was applied to the <br />WRC (Water Resource Council) Emerging <br />Energy Tedmology Studies. Further improve- <br />ments were made during this. study period. In <br />1979, CRSS was used by the Office of At- <br />mospheric Research. Bureau of Jl""".m~non, to <br />evaluate the potential uses and effects of <br />weather. modification or precipitation enhance- <br />ment. In 1980, CRSS was used to produce data <br />for the "Tenth Biennial Report on the Quality <br />of the Colorado River." In 1981, CRSS was <br />used to furnish data for WRC Emerging Energy <br />Technology Studies in the Lower Colorado <br />Basin. With e:u:h use of the CRSS. improve- <br />ments are made. The Bureau of p....l~m~non <br /> <br />. <br /> <br />has accepted CRSS as the primary tool for <br />simularloDS of the Colorado River System. <br />Other models and methods used to indicate im- <br />pacts of operational and developmental ad- <br />inctm-ts on the Colorado River arc gradually <br />being phased out. The CRSS is supported tech- <br />DicaIIy by a T....hn;ca1 M~n~8""'ent Team, and <br />administrative! by a Steering Committ~. This <br />support draws from personnel in the Upper and <br />Lower Colorado Regional Offic:es and the <br />Enr'l:ering and Research Center. <br /> <br />Documentation <br /> <br />The complete dOc:""l....t..noa of the CRSS is <br />com..m..t in eight parts: <br /> <br />. 1.
