Book Description: Groundwater and surface water features are linked and function as a continuous hydrologic system. Conceptual models of groundwater exchange with streams, lakes and wetlands are developed. Tools and models used to identify exchange locations, rates, directions, and timing are provided along with case studies illustrating method application. This book advances hydrogeologist’s ability to conceptualized groundwater-surface water exchange and recognize these processes in natural and impacted streams, lakes and wetlands. It provides a foundation for the design and implementation of surface water feature preservation and restoration actions.
