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.

Streamflow gain/loss in the Republican River basin, Nebraska, July 1975 Streamflow gain/loss in the Republican River basin, Nebraska, July 1975
This arc and point data set contains streamflow-measurement sites and reaches indicating streamflow gain or loss under base-flow conditions along Republican River tributaries in Dundy and Chase Counties, Nebraska during July 14 to 18, 1975 (U.S. Geological Survey, 1976). The streamflow measurements were made to obtain data on ground-water/surface-water interaction. Flow was observed...

Effects of surface run-off on the transport of agricultural chemicals to ground water in a sandplain setting Effects of surface run-off on the transport of agricultural chemicals to ground water in a sandplain setting
An experiment was conducted at a depressional (lowland) and an upland site in sandy soils to evaluate the effects of surface run-off on the transport of agricultural chemicals to ground water. Approximately 16.5 cm of water was applied to both sites during the experiment, representing a natural precipitation event with a recurrence interval of approximately 100 years. Run-off was...

Effects of topography on the transport of agricultural chemicals to groundwater in a sand-plain setting Effects of topography on the transport of agricultural chemicals to groundwater in a sand-plain setting
Geochemical data were collected to investigate the effects of topography and focused recharge on the transport of agricultural chemicals to groundwater through sandy soils. The research was done at a topographically high (upland) site and a depressional (lowland) site within a corn field. Agricultural chemicals that move readily with water were most directly affected by focused recharge...
