These models are intended for planning type investigations of the <br />effect of management strategies, proposed water development projects, instream <br />flow filings, compact issues, etc. <br />· Simulation models to estimate consumptive uses for crops and other uses in the <br />western slope. The Blaney Criddle method estimates crop consumptive use on a <br />monthly basis and the Penman Monteith method is appropriate when adequate <br />daily data exists. <br />· "Big River" models from the Bureau of Reclamation have been implemented in <br />CRDSS. These monthly planning models include the Colorado River Simulation <br />System (CRSS) for long term analysis of major reservoir operations, including <br />Lake Powell and Lake Mead, and water allocation strategies in the full Colorado <br />River Basin; and the Annual Operating Plan model (24 month simulation model) <br />that the Bureau uses to develop more short term operating strategies at Lake <br />Powell and Lake Mead. These models may be replaced with models currently <br />under development by the Bureau in year 3 of the CRDSS Project. <br /> <br />DWR/CWCB Computer Strategy atld CRDSS <br />The large secured database being developed for CRDSS and the multi-user environment <br />dictated that the system be developed in a workstation environment. The current concept <br />of the CRDSS computer system and access to that system includes. <br />· A centralized, workstation based, database in Denver containing the tabular data <br />related to water rights, ditch diversions and reservoir contents, climate, and <br />streamflow. It is envisioned that the CRDSS database system will eventually be <br />merged with the DWR proposed HYDROLASE database system such that the <br />there is only one master database to maintain and access. <br />· Access to the tabular CRDSS data by users would occur through the use of high <br />end personal computers connected to the internet through a relatively high speed <br />communication line (64 kbps or higher) and use the data browsers being <br />developed by CRDSS or local spreadsheets, etc. The user would have the ability <br />to transfer data and information from the CRDSS system to his local system. <br />· The CRDSS map viewer would be accessed through the same high end PCS, high <br />speed communication links and graphical remote terminal access software. <br />However, because of access time issues, primary maps would likely be placed <br />locally on the user's PCS. <br />· It is envisioned that a user of the water resource planning, consumptive use, and <br />"Big River" models could either access the workstation models remotely through <br />graphical terminal emulation or download the base program modules and data for <br />operation on his Pc. It is noted that each model will have an official baseline <br />scenario stored on the workstation which the user can adapt to his problem setting. <br /> <br />May 31, 1995 <br /> <br />2 <br />
