1. The proposal in the context of the CHy programme of work Paul J. Pilon Advisory Working Group Member (Leading Activities associated with Basic Systems (Hydrometry and Hydraulics) Geneva April 25-27, 2007

2. CHy Terms of Reference Objective: –Develop a proposal and implement a project to assess the performance of flow measurement instruments and techniques against WMO standards Expected Output/Outcomes: –Publications on the performance of flow measurement instruments and techniques –Identification of new technologies and practices for potential inclusion in HOMS Guidance material, manuals… Success is dependent on contributions and participation on individuals and organizations

3. Overview of Approach Develop a framework and identify/build the required “infrastructure” that will allow: –development of assessment capabilities –posting of results in agreed upon formats so that they may be “pooled” and used by others –Understanding the limitations of the instruments and techniques the uncertainty of the estimates of flow Draft proposal –Purpose and scope –Approaches to be taken in the project –Implementation Plan (timelines, key players, associated costs)
