Brianna Williams
Brianna is a geographer working with the New Jersey Water Science Center Integrated Hydrology Investigation Team
Brianna is a member of the Environmental Health Mission Area’s geospatial Core Technology Team (CTT), and currently resides in Tucson, AZ. Her team utilizes landscape and point source variables to understand what is happening in water bodies and how that might impact the environment and human health. Some of these projects include analyses for endocrine disrupting compounds in the Chesapeake Bay watershed, aquifer contamination nationwide, and Harmful Algal Blooms offshore and in lakes and streams. Brianna began at the USGS in 2011 as a Pathways Intern in the Eastern Geographic Science Center and joined the NJWSC in 2017. Since joining the bureau she has had the opportunity to participate in a variety of projects including field work in Micronesia, stormwater best management practices research, cartographic support for science centers and groups, and outreach to high school students.
Science and Products
Understanding the Effects of Stormwater Management Practices on Water Quality and Flow
Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on...
Geospatial Analyses and Applications Core Technology Team
About the Research The Geospatial Analyses and Applications Core Technology Team (CTT) as part of the Environmental Health Program collaborates with teams across USGS to develop and apply geospatial analytical methods to answer broad-scale questions about source-sink and cause-effect relationships between contaminants and vulnerable communities.
Current Period Statistics
The Current Period Streamflow Statistics project is computing low flow statistics for both a historic (1950-1979) and more recent (1990-2019) 30-year period. The computed statistics will provide information about streamflow changes over time and an evaluation of more recent streamflow conditions. The project will also present land-use changes, precipitation patterns, and water use in the...
