<br />. <br /> <br />. <br /> <br />HIS -- HERE'S HOW IT WORKS <br /> <br />(...,,,- <br />,.~~ <br /> <br />At State, U.S.G.S., and privately operated gauging stations, <br />COMSAT/ERT has installed equipment to record water stage height <br />every 15 minutes. This information is then beamed to a satellite in <br />3-hour segments (lS-minute segments during flood events), and may be <br />recalled via an HIS user's computer terminal. The terminal may be <br />hooked to a telephone 1 ine anywhere in the Uni ted States. It is <br />important to note that HIS is completely redundantl that is, each <br />data transmittal can be done more than once on separate equipment to <br />avoid data loss due to faulty transmission or equipment failures. <br /> <br />HIS -- Not Just a Data Collection System <br /> <br />00 <br /> <br />c. <br /> <br />~ <br /> <br />HIS is a broad set of information services, not merely a data <br />collection system. Whatever ypur water-related need, if it can be <br />met through data collection, COMSAT/ERT can customize HIS to assist <br />you. <br /> <br />HIS REPORTS CURRENTLY AVAILABLE <br /> <br />You can receive HIS reports once a day or 24 hours a day, if <br />you prefer. 'I'he following reports, printed out automatically at a <br />user's request, are currently available. Others may be generated to <br />meet a participant's specific needs. <br /> <br />1. <br /> <br />LISTDIS <br /> <br />Produces a tabular report of discharge recorded <br />every 15 minutes for a selected station or <br />network of stations. <br /> <br />2. <br /> <br />DAYA va <br /> <br />Produces a.report of daily averages of discharge <br />and provides a summary of data capture for a <br />station or network of stationsl can display <br />informa tion. for a single day or for several days. <br /> <br />Produces a tabular report of reservoir volume <br />recorded every 15 minutes for a station or <br />network of stations (if reservoirs) for the <br />specified time period. <br /> <br />Produces, in format similar to USGS daily flow <br />report, a summary of mean volumel can display <br />inf.orma tion for a single day or for sever al days. <br /> <br />3. <br /> <br />LIS'I'VOL <br /> <br />4. <br /> <br />DAIL YVO L <br /> <br />You can request reports in plot form. Or, you can order a full <br />schematic (from the PSCHEMATIC program) of a river showing tributary <br />inflows, diversions, and river flows above and belOW the confluence <br />of the tr ibutar ies. This format is especially useful dur ing flood <br />alerts. Equally important, all computer reports can include data <br />from the latest satellite transmissionl hence the water flow <br />information can be as recent as the last 15 minutes.
