Short Biography

Rick Webb is a research hydrologist with the Reaction-Transport Modeling in Groundwater and Watershed Systems project in the U.S. Geological Survey's National Research Program. Rick grew up on the shores of the Atlantic and later the Great Lakes. Beaches, jellyfish, hurricanes, and alewive dieoffs all left indelible memories that helped shape Rick's career studying waters both salty and fresh. As an undergraduate physical scientist working for NOAA, Rick deployed current meters in Lake Erie. After graduating with a BS in marine geology in 1982, Rick landed on the island of Puerto Rico for a two week vacation. The two week vacation turned into an eighteen year tenure with the Puerto Rico Department of Natural Resources and U.S. Geological Survey during which he studied anthropogenic impacts on coastal waters and upland watersheds. In 1999, Rick and his family moved to Denver, Colorado to better understand fundamental processes driving water and solutes through watersheds from the continental divide to tropical rain forests.

Watershed hydrology

Image of Current Focus for Watershed hydrology

Using numerical modeling of hydrology and aqueous geochemistry, I seek to better understand the processes controlling water, energy, and biogeochemical fluxes over a range of temporal and spatial scales. Over the last ten years I have worked with five pristine watersheds of the Water Energy and Biogeochemical Budget Project and five agricultural watersheds included in the National Water Quality Assessment.
