avid is a hydraulics engineer specializing in infrastructure hydraulics, including pressure surge analysis, Computational Fluid Dynamics (CFD) modeling, and physical modeling. He has analyzed pressure surges (water hammer) in pipe systems up to 30 ft in diameter conveying 20,000 cfs and has completed hundreds of transient analyses for large water distribution systems, transmission pipelines, pump stations, well fields, wastewater force mains, water treatment plants, and hydroelectric facilities. These analyses cover pump power failure, pump startup, valve operations, turbine load variations, and pipeline rupture events. He has also successfully calibrated hydraulic transient analysis software using field and laboratory measurements.
David has prepared expert opinion reports for court cases related to pipeline transient pressures. He has applied CFD to evaluate circulation patterns and water age in potable water reservoirs, mixing in de-aeration vaults, and analyzed open channel flow conditions in pipeline systems up to 144 inches in diameter. Additionally, he has conducted field investigations of pump stations to troubleshoot operational issues with pumps, valves, and wet wells.
