About

Dr. Robert Annear (Rob) is an environmental engineer with 25 years specializing in hydrodynamic and water quality modeling. Rob supports clients with regulatory permits and requirements, drinking water studies, surface water system assessments, climate change studies, receiving water modeling and analyses, Total Maximum Daily Loads (TMDL) development, implementation and compliance, Endangered Species Act (ESA) compliance, Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Resource Conservation and Recovery Act (RCRA), Natural Resource Damage Assessment (NRDA) studies, Federal Energy Regulatory Commission (FERC) relicensing of hydropower facilities and water quality management for multiple uses (supply, salmon, recreation etc.). He has in-depth experience in the development, calibration, and use of hydrodynamic and water quality models (1-D, 2-D, and 3-D) throughout the US in rivers, reservoirs, estuaries, and coastal and ocean environments. Rob has also served as Expert Witness in cases involving hydrology, water rights; and hydrodynamic, sediment transport and chemical fate and transport modeling. He has successfully led multidisciplinary teams of professionals, including managing projects, budgets, workflow processes, and quality control and assurance.
