Richard Webb

Rick Webb is a research hydrologist with the Reaction-Transport Modeling in Groundwater and Watershed Systems project in the U.S. Geological Survey's Water Resources Mission Area. 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.

Career Plans and Objectives

As a steward of the environment, I work with colleagues to understand the processes that 1) shape the surface of the earth and 2) change the composition of the water.  This information can then be used to evaluate and manage our limited resources. Most challenging is the need to compile and synthesize a wide array of data from multiple sources.  This may involve state-of-the-art signal processing or using a sextant to better locate a study site. My background and interests are centered on the premise of understanding the global picture while attempting to solve local  problems in our streams, rivers, lakes and oceans.
