Tisa River Basin Hydrologic Data Collection Program

Real-Time Streamflow Data Available on the World Wide Web

Telemetered systems are used when current or real-time information on gage height, streamflow, or weather parameters is needed.  Real-time gage-height information is necessary for maintaining reservoir levels and forecasting floods and also is used for other purposes.  The most common telemetered system is the satellite data-collection system.  From an antenna attached to the roof of a gage house, electronic signals are transmitted to a satellite orbiting the earth.  The data then are retransmitted via the GTS phone line to the USGS computer systems that make the data available on the Internet.  In 2005, a satellite receiver was installed at the SWMC offices in Uzhhorod. The receiver allows direct reception of all hydrologic data collected at the gaging stations.

Real-time hydrologic information for all stations instrumented as part of the Ukrainian program is available to the general public at:
