Water and Ecosystems Management

Integrated Assessments for Water Supply and Water Quality Issues

Global water supply and water quality problems are addressed more efficiently by adopting an integrated, watershed-based perspective. Our experts in water and ecosystems management are at the forefront of efforts to examine water supply and water quality issues in the U.S. and around the world. We follow a multidisciplinary approach to solving water resource problems by combining expertise in hydrology, ecology, engineering, and information technology.
