This manual provides a series of standard designs for streamgaging cableways used by the U.S. Geological Survey (USGS). It also provides helpful information on construction, inspection, and maintenance of cableways. Users of design recommendations are cautioned to follow sound engineering practice in selection of system components for a specific site. Accepted industry standards are referenced to facilitate procurement of materials where appropriate.

ADR. Analog-to-Digital Recorder; a recorder that punches data values as binary coded digits on paper tape at preselected time intervals for digital computer processing. Analog. Graphical or electrical representation of variations in quantities such as voltages, resistance, water levels, etc. CDCP. Convertible Data Collection Platform; a battery-powered telemeter that transmits data from a remote field site to a geostationary or polar orbiting satellite for relay to a ground-receive site. DARDC. Device for Automatic Remote Data Collection; a battery-powered telemeter that transmits observed field data from a remote site when interrogated either by telephone or radio link. POP. Data Collection Platform; a battery-powered telemeter that transmits observed field data from a remote station to a polar orbiting satellite for relay to a centrally located ground-receive site. GOES. A Geostationary Observational Environmental Satellite operated by the National Oceanic and Atmospheric Administration (NOAA). The satellite used in this study is in orbit above the Earth's equator at an altitude of about 22,000 miles and remains continuously over the same point on the Earth. Ground-receiving station. A communications facility that receives, records, and relays information from a satellite. HYDREC S. Hvdrologic Data Real-time Computer Processing System. Data received via satellite relay are entered into WATSTORE for near real-time processing. HYDRECS also provides reference and performance information about field sites that are transmitting data for satellite relay. Land line. Standard or dedicated telephone line that provides direct two-way communication between two points. National Center computer system. The U.S. Geological Survey computer system at Reston, Va. The National Center water-data files are accessible to various Survey District offices by terminal connection.Real-time data. Real-time data values are immediately available to users.Redundant data. -Data transmitted from a field site telemeter that were included in a previous transmission. ROMP. Regional Observation and Monitor-Well Program; a program administered by the Southwest Florida Water Management District to provide an integrated, District-wide network of hydrologic data collection for ground-water wells. Sensor. A gage or other detection device that measures change in hydrologic variables or parameters. Telemeter. A device that transmits digital or digital encoded data from one point to another. The CDCP is a telemeter that is battery powered and transmits data from ground-based sensors to the GOES satellite on specially assigned frequencies.
