Rob specializes in guiding clients through environmental permitting at the federal, state, and local levels. He also conducts assessments of complex surface water systems for Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Resource Conservation and Recovery Act (RCRA) sites; prepares natural resource damage assessment (NRDA) studies; and helps clients meet total maximum daily load (TMDL) requirements. He frequently consults on challenges related to multi-objective water quality management for municipal water supplies, fisheries, and recreational uses.
Rob's experience includes developing and calibrating 1-D, 2-D, and 3-D hydrodynamic, sediment transport, and water quality models of reservoir, riverine and estuarine systems.
He has conducted numerous peer reviews of surface water models for agencies such as the U.S. EPA, the U.S. Bureau of Reclamation, the Oregon Department of Environmental Quality, and the Washington Department of Ecology. He also has aided clients in the relicensing of hydropower facilities through the Federal Energy Regulatory Commission. On multiple occasions Rob has provided litigation support on matters involving hydrology; water rights; and hydrodynamic, sediment transport and chemical fate and transport modeling. He also has performed climate change impact studies and modeling to support long and short term planning efforts.
Rob continues to advance the state of the practice as an adjunct faculty member in the Civil and Environmental Department at Portland State University (PSU), where he teaches undergraduate and graduate courses in water resources engineering, urban watershed hydrology and temperature modeling. He has also led water quality modeling training workshops and serves on the master's thesis committees for the same department.
In addition, Rob is a reviewer for various water resource and hydrologic journals and has served on national water quality grant review panels for the U.S. EPA. He frequently presents at industry conferences on the topic of surface water modeling, sediment transport, and chemical fate and transport processes.
