Dr. Richard Janda of the USGS began a channel monitoring program in Redwood Creek in northern coastal California in 1973. The USGS continued this work through 2013, when the Research Geologist, Dr. Mary Madej retired. This effort produced 40 years of channel change data in rivers that were disrupted by severe erosion following timber harvest of old-growth redwood forests, a portion of the program's data (plus 1953 data) has been preserved in this data release. Original field surveys documented bank erosion, aggradation, and degradation at 60 cross-sectional transects at annual or biannual timesteps. Three river reaches also have long-term longitudinal channel bed surveys which document the distribution and development of pool channel features and other aquatic habitat units. Preserved survey data are provided in CSV format on the Cross Sectional Data and Longitudinal Profile Data ScienceBase child items, along with respective metadata records. Project level metadata and supplementary materials are available on the main ScienceBase page.
