Low-Flow, Base-Flow, and Mean-Flow Regression Equations for Pennsylvania Streams

Low-flow, base-flow, and mean-flow characteristics are an important part of assessing water resources in a watershed. These streamflow characteristics can be used by watershed planners and regulators to determine water availability, water-Introductionuse allocations, assimilative capacities of streams, and aquatic habitat needs. Streamflow characteristics are commonly predicted by use of regression equations when a nearby stream flow-gaging station is not available.
