Samuel Harrison Caldwell

Biography

Sam Caldwell joind the Survey as a Pathways Student in 2018 and was converted to a hydrologist in 2019. His work is mainly centered on understanding groundwater dynamics in the Virginia Coastal Plain using groundwater level analysis, electromagnetic resistivity techniques, photogrammetry, and various scales and types of remote sensing data.

Much of Samuel's project work focuses on the Virginia Coastal Plain in Virginia Beach and the Eastern shore. He leads a groundwater level and specific conductivity monitoring network in Virginia Beach that includes an electromagnetic induction logging network to monitor for saltwater intrusion, as well as a groundwater quality sampling element. Additionally, he is responsible for an electromagnetic induction logging network on the Eastern Shore of Virginia to monitor for salwater intrusion. He aslo leads a water quality sampling effort in Suffolk, VA in collaboration with the Hampton Roads Sanitation District's SWIFT project monitoring how water injected into the Potomac aqufer is affecting and moving through the nearby groundwater system. He has worked on several remote sensing and photogrammetry projects at a variety of scales with LSPIV, visual light, multispectral, and thermal infrared imagery. He graduated from Amherst College with B.A. in Geology and obtained an M.S. in Earth Sciences from Syracuse University in 2018.
