Sheila Murphy is a Research Hydrologist for the USGS Water Resources Mission Area.
Sheila Murphy is a research hydrologist who focuses on how disturbances (such as wildfire, floods, hurricanes, land use change) alter watershed response, water quality, and water quantity. Her recent research has evaluated the effects of wildfire on water quality in the western U.S., and the hydrologic and geochemical responses to land cover change and hurricanes in a tropical forest in Puerto Rico.

Water Quality After Wildfire
Wildfires pose a substantial risk to water supplies because they can lead to severe flooding, erosion, and delivery of sediment, nutrients, and metals to rivers, lakes, and reservoirs. The USGS works with federal and state land managers and local water providers to monitor and assess water quality after wildfires in order to help protect our Nation’s water resources.
Future of Aquatic Flows: Towards a Synthesis of Changing Hydrology Under Increasing Climate Change and Disturbance Pressures
Understanding the paths by which water flows through the landscape is critical for providing fresh water for human use, maintaining ecosystem function, and better predicting how disturbances such as fire or drought may impact water quantity and water quality. Yet projected changes in climate, disturbances, and land use , are likely to alter hydrologic flow paths, and .natural resource managers inc
Developing a "fire-aware" stream gage network by integrating USGS enterprise databases
Wildfires affect streams and rivers when they burn vegetation and scorch the ground. This makes floods more likely to happen and reduces water quality. Public managers, first responders, fire scientists, and hydrologists need timely information before and after a fire to plan for floods and water treatment. This project will create a method to combine national fire databases with the StreamStats w
Connections between Forested and Urban Landscapes and Implications for Water Supply
Interactions between forested and urban landscapes can lead to reciprocal effects that have substantial impacts on water supply and ecology. Air pollution from urban and forested landscapes can be deposited on adjacent forests, while forest disturbance, such as wildfires and floods, can remobilize those contaminants. Additionally, pollutants from legacy land use (e.g., mining) can also be...
