Summary:
This resource uses discharge data from three of NEON's wadeable stream sites to illustrate how streams can differ in their flow regimes using graphical analysis of annual hydrographs.

Description

The flow regime of a river can tell us a lot about its ecology. But how do we measure and understand the flow regime of different streams? One of the first steps is to examine a river’s hydrograph, across an entire year. This way, seasonal changes in stream discharge can be quantified, or typical responses to precipitation events and intermittent flows may be identified. Flow regime also depends on the surrounding watershed and its climate or geological context. Different climates and geographic location play a role in understanding differences among stream flow regimes.

The National Ecological Observatory Network (NEON) has >23 wadeable stream sites across the U.S. (from Alaska to Puerto Rico) where stream discharge is monitored. This resource uses a subset of these sites and their data to explore how climate and watershed context can affect stream hydrology.
