Streamflow refers to the movement of water in rivers and streams, measured as the volume of water passing a specific point over time. It is typically expressed in cubic feet per second (cfs) or cubic meters per second (cms). Streamflow is influenced by various factors, including rainfall, snowmelt, and human activities such as dam operations and water withdrawals. Monitoring streamflow is essential for managing water resources, predicting floods, and maintaining healthy ecosystems. Organizations like the United States Geological Survey (USGS) track streamflow data to provide valuable information for scientists, policymakers, and the public, ensuring sustainable water management practices.
