Erik Smith

Biography

Erik Smith has been a hydrogeologist with the U.S. Geological Survey since 2004.  Erik started as a student while finishing a MS in Geology from the University of Minnesota.  In 2005, Erik transferred to the Iowa Water Science Center to work as a supporting scientist and full-time hydrologist on the NAWQA program's Agricultural Chemicals Transport (ACT) team. During the ACT tenure, Erik assisted in all aspects of the South Fork Iowa River's ACT project, including the management of an extensive groundwater monitoring network, groundwater and surface water sampling, and instrumentation of an in-field subsurface drainage monitoring site. In 2008, Erik moved back to Minnesota to complete work on a PhD tied into the Iowa ACT project. Erik's research during this period focused on the spatial and temporal variability of preferential flow in a subsurface-drained landscape.

Since graduating from the University of Minnesota in 2011, Erik has been a full-time hydrologist with the Upper Midwest Water Science Center (Minnesota). His current research focuses on CE-QUAL-W2 modeling of glacial and riverine lakes, EFDC modeling of estuary and reservoirs, SWB modeling to estimate recharge across Minnesota, and groundwater sustainability. Additionally, Erik continues his research on the impacts of agricultural drainage on groundwater.
