Integration of environmental monitoring networks
Integration of environmental monitoring networks: Geological Survey

  • Comprehensive, multi-dimensional study of environmental problems and their linkages

  • Broader dissemination of monitoring technologies

  • Greater operational efficiency


Elements of a back bone network
Elements of a “back-bone” network: Geological Survey

  • Consistent core variables

  • Standard sampling and calibration protocols

  • Integrated data management driven by internet distribution and GPS systems

  • EPA Estuarine Reserves

  • NOAA Estuarine Status and Trends network

  • NOAA ocean current and weather buoys

  • USGS Streamgaging stations


Streamgaging Geological Survey

  • Gage Network

  • 7,100 gages

  • 85 % real-time

  • Network Costs

  • $120M per year

  • About $12,500/gage

Network Funding

State / Local agencies 35%

USGS Coop program 25%

OFA 18%

Mixed 15%

USGS NSIP 7%

  • Real-time streamflow

  • Flood and High flow

  • Monthly Conditions (and historic)

  • Comparison of today and POR

  • Comparison of 7-Day Average and POR

  • Below normal

  • Drought Watch

Radars

HydroAcoustics


Hydroacoustics
HydroAcoustics Geological Survey

  • Doppler principle

  • Fast and accurate

  • Not effective in shallow water

  • Used with boats or tethered from bridges

  • Can be used as side-looking, velocity index meters

Radars
Radars Geological Survey

Q=V A

  • Microwave radar for surface velocity only

  • Ground-penetrating radar for channel area

  • GPR doesn’t work well in high conductivity or great depth
