  1. UK Hydrometry WMO RA VI Hydrology Forum Koblenz 8-10 May 2012 Ann Calver (UK hydrological adviser & Commission for Hydrology advisory group member) Harry Dixon (National Water Archive)

  2. Raingauges rainfall radar synoptic site source: UK Met Office

  3. Raingauge densities • 4000+ rain gauges • Hourly, daily & monthly obs stored in MIDAS Partners with Met Office in raingauge network

  4. UK river flow gauging authorities Data archiving & guidance material National Water Archive Wallingford National River Flow Archive National Groundwater Level Archive

  5. River flow data retrieval http://www.ceh.ac.uk/data/nrfa/index.htm source: National River Flow Archive

  6. Groundwater levels National Groundwater Level Archive sites major aquifers sites of well water level observations http://www.bgs.ac.uk/research/groundwater/ datainfo/levels/ngla.html source: British Geological Survey; National Groundwater Level Archive

  7. Hydrometric summaries surface water groundwater reservoir stocks source: National Water Archive, Wallingford

  9. Developments and challenges – wider comments (1) • Network data generally fit for purpose; some • enhancements always desirable • Some networks rationally-designed, some • evolutionary • Investigation of implementation of new • technologies • General economic considerations • Cost of wider availability of data

  10. Developments and challenges – wider comments (2) • Involvement in standards development/ • enhancement • Further potential sources of data – researchers, • the public • Planning for future water management scenarios • Consideration of appropriate use of spatial • transposition of data anncalver@lwrc.co.uk
