Interactive Display and Query of Near Real-Time Data from a Hydrologic Alert Network

Proceedings of the 1993 Georgia Water Resources Conference, April 20-21, 1993, Athens, Georgia.Within the U.S. Geological Survey (USGS), an extensive hydrologic network exists to record and transmit currently sensed data to the Automated Data Processing System (ADAPS; Dempster 1990). Data values are recorded at field sampling sites on electronic data-col1ection platforms (DCP). These values are transmitted by satellite to a ground station and by telecommunications lines to a USGS District office. There they are processed within ADAPS on a Prime minicomputer. Data that exceed predefined thresholds are identified as alert values. These data help alert water-resource specialists that hydrologic events are occurring. Knowledge of the current alert status at sampling sites within a State is of critical importance during floods, hurricanes, and other extreme hydrologic events. This report describes a system of computer programs designed to display current information from a hydrologic alert network.Sponsored and Organized by: U.S. Geological Survey, Georgia Department of Natural Resources, The University of Georgia, Georgia State University, Georgia Institute of TechnologyThis book was published by the Institute of Natural Resources, The University of Georgia, Athens, Georgia 30602 with partial funding provided by the U.S. Department of Interior, Geological Survey, through the Georgia Water Research Institute as authorized by the Water Resources Research Act of 1984 (P.L. 98-242).
