Hydrologist, New Mexico Water Science Center
Jeb Brown is a hydrologist at the New Mexico Water Science Center. He received a bachelors degree in Biology and a Masters in Water Resources from the University of New Mexico. Since joining the USGS in 2007, he has devoted his career to studying fluvial sediment transport and specializes in researching surrogate methods for estimating suspended-sediment concentration. Presently, his research focuses on hydroacoustic, densimetric, and turbidity surrogates for suspended sediment.

Suspended-sediment transport and water management, Jemez Canyon Dam, New Mexico, 1948–2018
Construction and operation of dams provide sources of clean drinking water, support large-scale irrigation, generate hydroelectricity, control floods, and improve river navigation. Yet these benefits are not without cost. Dams affect the natural flow regime, downstream sediment fluxes, and riverine and riparian ecosystems. The Jemez Canyon Dam in New Mexico was constructed in 1953 by the U.S. ArmyAuthorsJeb E. Brown, Anne-Marie Matherne, Justin K. Reale, Keely E. MiltenbergerIn situ densimetric measurements as a surrogate for suspended-sediment concentrations in the Rio Puerco, New Mexico
Surrogate measurements of suspended-sediment concentration (SSC) are increasingly used to provide continuous, high-resolution, and demonstrably accurate data at a reasonable cost. Densimetric data, calculated from the difference between two in situ pressure measurements, exploit variations in real-time streamflow densities to infer SSCs. Unlike other suspendedsediment surrogate technologies basedAuthorsJeb E. Brown, John R. Gray, Nancy J. HornewerNon-USGS Publications**

Investigations of Sources of Contaminants of Concern in the San Juan River
Metals attached to suspended sediments or dissolved in river water pose a potential health risk to communities that depend on that water for agricultural and domestic uses. Exceedances of Navajo Nation surface water quality standards for metals (especially lead and arsenic) indicate that communities on the Navajo Nation along the San Juan River are exposed to this potential risk. Sources for these...Sediment Acoustics
The U.S. Geological Survey recognizes the need to provide sediment acoustic training and to develop standardized techniques and practices.New Mexico Water Science Center Sediment Field Program
Sediment is fragmental material transported by, suspended in, or deposited by water or air, or accumulated in beds by other natural agents. Sediment particles range in size from large boulders to colloidal-size fragments and vary in shape from rounded to angular. They also vary in mineral composition and specific gravity. Sediment is derived from a parent material subjected to erosional processes... - Multimedia
