Sheila Murphy
Sheila Murphy is a Research Hydrologist for the USGS Water Resources Mission Area.
Sheila Murphy is a hydrologist who works on assessing and predicting how disturbances (such as wildfire and floods) affect water availability. In 2023 Sheila received a Superior Service Award from the Department of the Interior for making fundamental advancements in understanding the effects that wildfire can have on water supplies.

Aquatic-terrestrial linkages control metabolism and carbon dynamics in a mid-sized, urban stream influenced by snowmelt Aquatic-terrestrial linkages control metabolism and carbon dynamics in a mid-sized, urban stream influenced by snowmelt
Freshwater streams can exchange nutrients and carbon with the surrounding terrestrial environment through various mechanisms including physical erosion, flooding, leaf drop, and snowmelt. These aquatic-terrestrial interactions are crucial in carbon mobilization, transformation, ecosystem productivity, and have important implications for the role of freshwater ecosystems in the global...

U.S. Geological Survey wildland fire science strategic plan, 2021–26 U.S. Geological Survey wildland fire science strategic plan, 2021–26
The U.S. Geological Survey (USGS) Wildland Fire Science Strategic Plan defines critical, core fire science capabilities for understanding fire-related and fire-responsive earth system processes and patterns, and informing management decision making. Developed by USGS fire scientists and executive leadership, and informed by conversations with external stakeholders, the Strategic Plan is...

Wildfires: Identification of a new suite of aromatic polycarboxylic acids in ash and surface water Wildfires: Identification of a new suite of aromatic polycarboxylic acids in ash and surface water
Ash and surface water samples collected after wildfires in four different geographical locations (California, Colorado, Kansas and Alberta) were analyzed. The ash samples were leached with deionized water, and leachates were concentrated by solid phase extraction and analyzed by liquid chromatography/time-of-flight mass spectrometry. In addition, three surface water samples and a...

Summer runoff generation in foothill catchments of the Colorado Front Range Summer runoff generation in foothill catchments of the Colorado Front Range
Climatic shifts, disturbances, and land-use change can alter hydrologic flowpaths, water quality, and water supply to downstream communities. Prior research investigating streamflow generation processes in mountainous areas has largely focused on high-elevation alpine and subalpine catchments; less is known about these processes in lower-elevation foothills and montane catchments. In...

Signatures of hydrologic function across the critical zone observatory network Signatures of hydrologic function across the critical zone observatory network
Despite a multitude of small catchment studies, we lack a deep understanding of how variations in critical zone architecture lead to variations in hydrologic states and fluxes. This study characterizes hydrologic dynamics of 15 catchments of the U.S. Critical Zone Observatory (CZO) network where we hypothesized that our understanding of subsurface structure would illuminate patterns of...

Fates and fingerprints of sulfur and carbon following wildfire in economically important croplands of California, U.S. Fates and fingerprints of sulfur and carbon following wildfire in economically important croplands of California, U.S.
Sulfur (S) is widely used in agriculture, yet little is known about its fates within upland watersheds, particularly in combination with disturbances like wildfire. Our study examined the effects of land use and wildfire on the biogeochemical “fingerprints,” or the quantity and chemical composition, of S and carbon (C). We conducted our research within the Napa River Watershed...
