<br />Data transmissions are processed in an automated fashion on a real-time <br />basis. Data conversions including analog-to-digital. stage-to-discharge, and <br />mean daily values computations are performed in an automated fashion based on <br />user input. Data are automatically screened and appropriately flagged if they <br />fall outside of a user defined normal range. thus providing a basis for data <br />quality assurance. Data editing routines. with access controlled by user <br />name/password. allow for data base modification in both the real-time data and <br />the archival data base. Data for stations not in the monitoring network may <br />be entered manually, from computer-to-computer transfer. or by computer tape. <br /> <br />The data can be retrieved and output in various reports and graphics <br />formats. The most fundamental output format for the evaluation of flow data <br />is the hydrograph. Data from up to four stations or from four periods of <br />record for a single station can be plotted on a single hydrograph. <br /> <br />. The system ts a~l~ of providing flood warnings. If rjver condttions <br />surpass user identlfled high water levels, the system automatlcally sends out <br />warning messages to designated personnel by either computer-to-computer <br />communications or by delivering a voice-synthesized message over the phone, <br /> <br />E. Future System Developments <br /> <br />The satellite-linked monitoring system can be both expanded and enhanced <br />to increase its capabilities and effectiveness. The expansion of the state's <br />monitoring network and the enhancement of the system by the addition of other <br />sensor types will be limited by the availability of funds. The cost to <br />purchase and install GOES-linked data collection hardware at an existing <br />shelter is approximately $5.500 per station. Refer to Appendix A. Current <br />funding levels do not provide for capital expenditure beyond hardware replace- <br />ment costs. There is a large variety of sensor types available over a wide <br />cost range. Sensors are available that can interface with the Sutron DCP and <br />provide valuable data on a real-time basis. These include precipitation. air <br />temperature. water temperature. soil moisture, snow depth, solar radiation, <br />pH. dissolved oxygen. conductivity, wind direction and speed, humidity, and <br />soil temperature. Costs for specific sensors range from $300 to $4.500. <br />Refer to Appendix B. The need for additional data must be coupled with funds <br />from the state of Colorado and from various user groups to cover the costs. <br /> <br />The Office of the State Engineer, Division of Water Resources, can <br />justify the need for an additional 25 to 30 satellite-linked monitoring <br />stations to assist in water rights administration. This office is also <br />interested in real-time data that can assist in runoff forecasting and in dam <br />safety monitoring. Other state agencies including the Division of Wildlife <br />and the Department of Health identified the need for an additional 20 to 25 <br />stations. The Division of Wildlife is interested in monitoring minimum <br />streamflows and water quality relative to fisheries management. The Depart- <br />ment of Health is interested in monitoring basic water quality parameters. <br />The Office of the State Engineer has made the receive site and central <br />computer facilities available to any state agency desiring to get involved in <br />GOES-linked data collection. Technical expertise will also be provided on a <br />cooperative basis. <br /> <br />-19- <br />
