Research and Consulting Experience

Have written over 700 testing reports and proprietary reports as a result of research and consulting experience.

Hydraulic Structures and Physical Model Studies

  • Extensive experience performing hydraulic structure physical model studies on dams and spillways, pumping pits, power plant intakes, erosion control issues, channels, spillway basins, gated structures, control structures, outlet and energy dissipation structures, fish screens, bypasses, sewer and storm water systems.
  • Principle investigator or team member on more than 100 physical models of hydraulic structures.

Flow Measurement and Calibration

  • Personally responsible for over 1000 flow meter calibrations since 1987, which culminated in the authorship of over 400 flow meter test reports. These calibrations included: ultrasonic, venturi, nozzle, turbine, orifice, insert probe, magnetic, v-cone, coriolis, pressure differential, open channel and velocity probe type flow meters.
  • Consultant for flow meter applications, installation, design and field problems.
  • Consultant for field flow rate, velocity profile and loss coefficient measurements.

Valve Performance and Analysis

  • Performance test experience on most types of control valves and check valves including: detection and quantification of cavitation, determination of size and pressure scale effects, cavitation suppression, torque measurements, leakage tests, cycle tests, wear tests, and discharge and loss coefficient tests.
  • Valve cavitation computer programs.
  • Witness of on-site valve testing.

Hydraulic System Component Testing, Design, and Analysis

  • Laboratory friction loss and minor loss measurements in high density polyethylene drainage, PVC, concrete, corrugated steel, carbon steel, and cast iron pipe and fittings.
  • PVC pipe and fitting pressure, cycle and burst testing and witness testing.
  • Analysis of system design, pipe transients and failures.
  • Hydraulic system design.
