Hydrologic connectivity

Ephemeral and intermittent streams in the southwestern United States exist in a precarious balance between drying and flooding. These extreme flow characteristics structure the ecological processes and productivity of aquatic and riparian communities and shape species life histories over evolutionary time scales. Our research seeks to understand the patterns and drivers of hydrologic dynamism in dryland streams at multiple spatial and temporal scales in order to successfully protect and manage these ecosystems both today and in a future that faces substantial environmental change.
