Geomorphic Characteristics and Classification of Duluth-Area Streams, Minnesota
In 2003 and 2004, a geomorphic assessment of
streams in 20 watersheds in the Duluth, Minn., area
was conducted to identify and summarize geomorphic
characteristics, processes, disturbance mechanisms, and
potential responses to disturbance. Methods used to assess
the streams included watershed characterization, descriptions
of segment slopes and valley types, historical aerial
photograph interpretation, and rapid field assessments and
intensive field surveys of stream reaches. Geomorphic conditions
were summarized into a segment-scale classification
with 15 categories mainly based on drainage-network
position and slope, and, secondarily, based on geologic
setting, valley type, and dominant geomorphic processes.
Main causes of geomorphic disturbance included historical
logging and agriculture, and ongoing urban development,
human-caused channel alterations, road and storm
sewer drainage, ditching, hiking trails, and gravel pits or
quarries.
