River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts. River ecosystems are part of larger watershed networks or catchments, where smaller headwater streams drain into mid-size streams, which progressively drain.

Low-flow statistics are needed by water-resource engineers, planners, and managers to protect and manage the water resources of Alabama. The accuracy of these statistics is influenced by such factors as length of record and specific hydrologic conditions measured in those records. As such, it is generally recommended that flow statistics be updated about every 10 years to provide improved and Cited by: 1.

Updating Low-Flow Statistics at USGS Streamgages and Regionalization of Selected Low-Flow Characteristics for Alabama Streams. INTRODUCTION. As part of their mission to protect public health and aquatic ecosystems, Alabama state agencies need accurate and representative streamflow statistics to establish realistic and applicable criteria for both water quality and water quantity (fig.
