DENVER (AP) — Instrument-laden aircraft are surveying the Colorado high country this month as scientists search for better ways to measure how much water is locked up in the world's mountain snows —...

The Hydrologic Science Symposium poster was designed by Aaron Heldmyer The Hydrologic Sciences Graduate Program is excited to announce its 12th Annual Hydrologic Sciences Symposium! This year's theme is: "Collaboration and Connections - Protecting and Restoring Water Resources". The Symposium will take place April 6th and 7th at the SEEC...

WEBMOD model "buckets." Image: USGS NRP The USGS NRP recently released the Water Energy and Biogeochemical Model (WEBMOD) that simulates water and solute fluxes through watersheds. More specifically, the semi-distributed water-scale water-balance model simulates hydrologic and geochemical storages and fluxes on a daily time step. The model framework utilizes the...

The recent “atmospheric river” weather pattern that pummeled California with storms from late December to late-January may have recouped 37 percent of the state’s five-year snow-water...

2016 wildfire in Beaver Creek, CO As the Western US is projected to get dryer, research suggests a correlated increase in wildfire-derived aerosol loading. Yet the feedback between these factors and climate warming pose uncertainties in predicting future climate. A new study detailing the the relationships between aridity, aerosol loading,...

George Aiken joined the U.S. Geological Survey in March 1976 with the Central Region of the National Research Program (NRP) in Denver, Colorado. Before joining USGS, George earned a B.A. degree in Chemistry from Rutgers University. From 1976 to 1979, George worked with NRP’s Organic Hydrogeochemistry Project, and it was...
