Groundwater (GW) and surface water (SW) interactions have important implications for water quantity, water quality, and ecological health. The GW-SW interface is crucial as it actively regulates the transfer of nutrients, contaminants, and water between GW systems and SW environments. This presentation will focus on several examples utilizing land and water-based TEM methods. These methods permit highly productive and detailed characterization of properties relevant to GW-SW exchanges. The first case study will cover land and water-based surveys in Denmark to characterize groundwater pollution. The second will focus on land-based surveys to characterize alluvial deposits in Zimbabwe and the third will focus on land and water-based surveys to characterize lake-GW connectivity in South Africa.
Paul McLachlan is a postdoctoral researcher at the Aarhus University Hydrogeophysics Group, Denmark. He completed his PhD in 2019 at Lancaster University, UK, where he focused on geophysical characterization of groundwater-surface water interactions. During his time in Aarhus he has primarily been involved in water resource projects in both Europe and Africa, with a focus on TEM methods.
