Wesley Henson, Ph.D.
Wesley Henson is a Research Hydrologist in San Diego, California. His research focuses on developing decision tools and methods to improve water management for food and water security and water resource sustainability.
Wes grew up in the dusty parched deserts of northern Nevada. He holds degrees in Geology, Hydrogeology, and Agricultural and Biological Engineering. He began his career with the USGS in 2009 and currently leads a Food and Water Security Research Team. His team helps address critical water resource issues, both nationally and internationally. Much of his current work is centered in a key US agricultural region—the Central Coast of California.
His research centers on incorporating additional hydrologic processes in hydrologic models so they are more suitable to address a wide variety of the challenges water managers must address. These methods include:
- Methods for estimating recharge, runoff, and land use.
- Quantifying regional scale uncertainty in water budgets (e.g., Sea Water Intrusion)
- Evaluating aquifer vulnerability to contaminants
- Nitrate biogeochemistry, and
- Development and simulation of karst aquifer preferential flow paths.

CRT: Cascade Routing Tool to Define and Visualize Flow Paths for Grid-Based Watershed Models
The U.S. Geological Survey Cascade Routing Tool (CRT) is a computer application for watershed models that include the coupled Groundwater and Surface-water FLOW model GSFLOW and the Precipitation-Runoff Modeling System (PRMS). CRT generates output to define cascading surface and shallow subsurface flow paths for grid-based model domains.
MODPATH Observation Process (MODPATH-OBS)
The MODPATH-OBS (Hanson and others, 2013) computer program is designed to calculate simulated equivalents for observations related to advective groundwater transport that can be represented in a quantitative way by using simulated particle-tracking data.
