Surface Water Investigations
Surface water hydrology studies are vitally important in understanding the total hydrologic flow regime, not only to evaluate flow and water quality characteristics in the stream, but also the potential hydraulic and geochemical interactions with shallow ground water. HSA has over two decades of experience working on projects associated with surface water hydrology. HSA applies an ecosystem approach to its water quality work, focusing on biogeochemical linkages among biota, sediment, water, and the atmosphere. By integrating our water resources management, environmental engineering, and ecosystem management services, we are able to adopt a holistic approach to surface water issues.
HSA’s lake, stream, ground water, sediment, and marine water quality investigations have established HSA’s surface water quality group as regional water quality experts. Our multi-specialist approach to surface water quality management involves geologists, ecologists, chemists and engineers with expertise in a wide range of technologies, approaches and concepts. We offer a breadth of expertise in areas such as habitat and species analysis, lake management, flood protection, impact analysis, regulation compliance, monitoring of best management practices and low-impact development, open-channel and piped-flow gauging, and statistical analysis. HSA’s expertise encompasses successful planning, monitoring, and analysis strategies that have been applied to projects throughout the United States for clients that include federal, state, and local agencies; tribes; developers; and industry.
