Dr. Lehner鈥檚 research program focuses on the development of integrated concepts to analyze the possible impacts of global change (i.e., climate, land use, and socioeconomic change) on a multitude of water resources and freshwater conservation aspects across large scales. His research relies on novel hydrographic mapping and modeling approaches with applications ranging from global environmental change studies to assessments of the eco-hydrological effects of dam constructions, the fate of human-caused contaminants in river systems, environmental flow requirements, tradeoffs between hydropower production and aquatic resilience, and the development of system-scale freshwater management and protection strategies. His research also includes the design and development of pioneering global databases and digital maps related to rivers, watersheds, lakes, reservoirs, and wetlands, as well as their environmental and ecological characterizations (for signature products see ). These data developments have transformed global hydrological applications and enabled eco-hydrological modeling at a quality, resolution and extent that exceeds previous efforts.
