Commission for Hydrology (CHy) Activities
  • General
  • Technical Regulations Volume III – Hydrology
  • Terminology – International Glossary of Hydrology
  • Metadata
  • Provision of Guidance on QMF/QMS
  • Uncertainty Analysis
  • Joint ISO/WMO Standards
general
General
  • Inter-Commission Group on WIGOS (ICG-WIGOS) – Harry Lins, President CHy
  • Task Team on WIGOS Metadata (TT-WMD) – Tony Boston, CHy-AWG
  • Task Team on WIGOS Regulatory Material (TT-WRM) – Paul Pilon, CHy-AWG
  • Task Team on WIGOS Quality Management (TT-WQM) – Paul Pilon, CHy-AWG
  • Inter Programme Expert Team on WIGOS Framework Implementation Matters (IPET WIFI) – Paul Pilon, CHy-AWG
  • Review and develop material for the TT-WRM, TT-WMD and TT-WQM…
technical regulations volume iii hydrology
Technical Regulations Volume III -Hydrology
  • Review and revise material
    • Set-up editorial board
    • Review existing TRs
    • Use team of experts
    • Peer review material
international glossary of hydrology
International Glossary of Hydrology
  • Joint WMO and UNESCO effort – “Manual”
  • Periodically updated
  • Provides list of terms and their definitions in 4 languages
  • Standard terminology and definitions are of great importance
metadata
Metadata
  • Monitor and report on new developments on data exchange and protocols, data transfer formats, and data information
  • Test and apply WaterML 2.0 through pilot projects
    • Potential for new WMO standard for information exchange
    • Potential to register as joint WMO/ISO standard
provision of guidance on qmf qms
Provision of Guidance on QMF/QMS
  • Launch of QMF-H website
  • Provision of background material for NHSs as to benefits of standardization
  • Guidance on implementing a QMS including case studies
    • Use of templates
uncertainty analysis
Uncertainty Analysis
  • Continue implementing project to assess the performance of flow instruments and techniques
  • Website launched
  • Inclusion of a “working website”
  • Detailed project work plan developed
uncertainty analysis expected results
Uncertainty Analysis – Expected Results
  • Improved understanding of the accuracy of hydrometric instruments;
  • Appropriate selection or development of instrumentation that meets the measurement needs for water planning and management;
  • Standardization of hydrometric measurements and the computation of estimates of measurement uncertainty (known data quality to possibly improved quality of data);
  • Improved cooperation among NHSs.
how to do it
How to do it?
  • The approach should be easy to implement, “easily understood, and [should] generally [comprise] accepted procedure[s] for characterizing the quality of a measurement… [leading to] expressing its uncertainty.” (GUM, 1993)
    • Use of common terminologies and definitions
    • Systematic propagation of uncertainties and their estimation
    • Guide to the Expression of Uncertainty of Measurements (1993, 1995, 2008)
joint wmo iso standards
Joint WMO/ISO Standards
  • Undertake review of ISO and other standards used in hydrology and water resources
  • Specify which joint standards should be developed
  • Establish how they will be developed
  • (e.g., WaterML 2.0 to be a joint standards for information exchange)
