His research focuses on surface-water hydraulics and hydrology, focusing on methods to provide improved quantitative description of flows. Art brings a unique coupling of many years of field data-collection experience with extensive training and experience in numerical methods to simulate complicated hydrologic and hydraulics processes. He started his engineering career with several years performing aerial photo-control, topographic, and bathymetric surveys. He has worked as a hydrologist for the U.S.G.S for 12 years and started using hydroacoustics in 1993.
