This webinar will discuss groundwater and surface water interactions in two presentations:

Part I: Introduction (Judy Canova)Typical interactions between groundwater and surface water may vary in different regions depending on the types of climate that occur. This introduction focuses on principles and rudimentary cost-effective techniques that can be used to evaluate groundwater-surface water interactions with the expectation that groundwater discharge to surface water is typically not homogeneous and diffuse but rather heterogeneous and focused on preferential pathways of discharge. Case studies illustrating the evaluation of groundwater and surface water will be presented to demonstrate principles of characterization as well as the concepts of heterogeneity.

Part II: Bonita Peak Case Study and CSM (Ian Bowen)This presentation will cover a geophysics characterization approach used to understand ground water/surface water interactions at the Bonita Peak Mining District Superfund Site, and the impact the findings had on the Conceptual Site Model.
