U.S. Geological Survey, Hydrologic Instrumentation Facility

2. Instrumentation Assessments
Office of Surface Water – policy on flow measurement instruments
Water Science Centers – ad hoc & projects
Internal Specialty Workgroups – such as HAWG
Instrumentation Committee - ICOM
Hydrologic Instrumentation Facility – Testing Section

3. Instrumentation Standards
Techniques of Water Resources Investigations
Water Supply Paper by Rantz and others
Official Memoranda, Technical Offices
Official Reports – SIR, WRIR, and OFR

4. Testing Standards Dependent on Needs & Investigator
Simple comparisons with existing instrumentation in field
Simple “office” tests
Laboratory tests with traceable standards/references
Rigorous field experiments
Emerging demand for uncertainty analysis of measurements

5. Instrumentation Information
