Mark Sauter, M.S., P.E. (CA)
Vice President and Principal Engineer
Mr. Sauter heads the Hydraulic and Transient Analysis group. He gained comprehensive experience in the planning, design, construction and startup of wastewater treatment facilities while an employee for the City of Los Angeles and the County Sanitation Districts of Los Angeles County. His wastewater background serves as a specialized foundation for his applied experience in fluid flow analysis. With Flow Science, he has been responsible for the modeling and analysis of hydraulic transients in pipeline systems as a result of loss of power to pump stations, pump startup, and control valve operations and performs surge analyses for both water and wastewater systems.
Gang Zhao, Ph.D., P.E. (CA)
Dr. Zhao is currently a Principal Engineer at Flow Science. His field of specialization is hydrodynamics and water quality modeling. He also has experience in field tracer studies, hydrologic modeling, GIS analysis and NPDES permit applications. Dr. Zhao has primarily worked on hydrodynamic simulations of flows in rivers, estuaries, and coastal oceans, and analyses of wastewater discharge from diffusers. He has experience in every step of the modeling process, including field data analysis, development and implementation of the computational model, and interpretation and presentation of simulation results.
