Theodore B. Barnhart
Dr. Theodore B. Barnhart studies the connection between the mountain snowpack and streamflow.
Dr. Barnhart is interested in furthering the understanding of how changes in the mountain snowpack translate into changes in streamflow and how that process varies across landscapes, land cover types, and climate systems. He is also interested in understanding the water resources implications of the changing mountain snowpack and streamflow and the effects on downstream stakeholders. He uses numerical snowpack and hydrologic models for his research along with observational and remote sensing data sets.

Flow-Conditioned Parameter Grid Tools
The Flow-Conditioned Parameter Grid (FCPG) Tools are a Python 3 library to make FCPGs for either two-digit Hydrologic Unit Code (HUC2) regions, four-digit Hydrologic Unit Code (HUC4) regions, or other geospatial tiling schemes. These tools can be used in a Linux-based high performance computing (HPC) environment or locally on your system.
StreamStats Data Preparation Tools, version 4
A Python package to pre-process and hydro-enforce digital elevation models using hydrography features for use in the U.S. Geological Survey (USGS) StreamStats project.
