Matthew K Landon
Matthew Landon has been a Hydrologist with the U.S. Geological Survey since 1990.
He received a M.S. in Geology from the University of Minnesota in 1993 and a B.S. in Geology from the University of Kansas in 1987. He has conducted studies of groundwater hydrology and geochemistry in Minnesota, Nebraska, California, and Southeast Asia. He has been with the USGS California Water Science Center in San Diego since 2005, serving as Program Chief for the Groundwater and Geochemistry Projects Group from 2012-2016 and the California Oil, Gas, and Groundwater Projects Group since 2016.

Denitrification in the recharge area and discharge area of a transient agricultural nitrate plume in a glacial outwash sand aquifer, Minnesota Denitrification in the recharge area and discharge area of a transient agricultural nitrate plume in a glacial outwash sand aquifer, Minnesota
Recharge rates of nitrate (NO3−) to groundwater beneath agricultural land commonly are greater than discharge rates of NO3− in nearby streams, but local controls of NO3−distribution in the subsurface generally are poorly known. Groundwater dating (CFC, 3H) was combined with chemical (ions and gases) and stable isotope (N, S, and C) analyses to resolve the effects of land use changes...

Streamflow gain/loss in the Republican River Basin, Nebraska, October 1998 Streamflow gain/loss in the Republican River Basin, Nebraska, October 1998
This arc and point data set contains streamflow-measurement sites and reaches indicating streamflow gain or loss under base-flow conditions along the Republican River and tributaries in Nebraska during October 25 to 28, 1998 (Boohar, 2000). The streamflow measurements were made to obtain data on ground-water/surface-water interaction. Flow was observed visually to be zero, was measured...
