Faundeen, John F. 2018 Tabular Digital Data https://doi.org/10.5066/P9G0N0TN 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. Under the federal Clean Water Act of 1972, many rivers in the United States have been designated as "sediment-impaired" because the level of sediment in the river impacts beneficial uses, such as cold freshwater and estuarine habitats. In northern California about 60% of the region drains to rivers and streams that are considered sediment impaired. Land use disturbances, primarily timber harvest and road construction, have caused accelerated erosion on these steep forested hillslopes and the resulting loss of soil diminishes on-site productivity. The excess sedimentation in many northern coastal rivers also results in destruction of pool habitat and spawning gravel quality and has led to several types of salmonids being listed as threatened or endangered. This effort is a rare example of long-term monitoring of channel changes due to land use disturbances and subsequent watershed restoration efforts. River channel assessment consists of evaluation of channel stability (bank erosion, scour and fill, pool formation, and channel shifting) in streams and rivers. These data sets can be used to understand future river changes and provides an excellent baseline for incorporating climate change into channel morphologic studies. Studies of river changes in other regions can use this data set to compare channel response under different climatic and geologic conditions. The data in this release represent the subset of the full channel survey collection that was able to be fully quality controlled and verified against source files. Original field notebooks and Excel sheets are in the Redwood National Park archive in Orick, CA. The released data package includes cross sectional data and longitudinal profile data, both in tabular (CSV) form, CSDGM metadata describing each of these pieces, a shapefile providing locations of all cross sections in the collection (including ones not released) and supplemental materials on the main ScienceBase page. The supplements include a glossary, a mid-channel distance graphic, a field setting description, methodology description and an index that describes which cross section data are preserved in this release. 1953 2013 observed Complete As needed -124.04999999999998 -123.70499999999998 41.299 40.694 ISO 19115 Topic Category geoscientificInformation USGS Thesaurus watershed management geomorphology None river channel surveys fluvial geomorphology watershed restoration cross section survey longitudinal survey USGS Metadata Identifier USGS:57aa525fe4b05e859be091f6 Common Geographic Areas Humboldt California Redwood Creek Redwood National Park United States Dolason Creek Harry Wier Creek Emerald Creek Elam Creek Hayes Creek Bond Creek 44 Creek Fortyfour Creek Forty-four Creek None.

Stephens, T.A. 1982 publication U.S. Geological Survey Open-File Report 81-496 https://pubs.er.usgs.gov/publication/ofr81496 All cross sectional and longitudinal profile files were checked against original data sheets to ensure good quality. All processed data were quality controlled using Python and Microsoft Excel to ensure accurate and consistent carry over of information. See Cross Sectional and Longitudinal Profile metadata records for more details on the processes and quality control. The GPS readings of the cross section locations were taken in heavily forested areas, thus the estimated accuracy of these points is +/- 10 meters. Each longitudinal profile survey was based on an arbitrary benchmark elevation. See respective metadata records for more details. The data preserved in this release represent the subset of the full channel survey collection that was able to be fully quality controlled and verified against source files. Original field notebooks and Excel sheets are in the Redwood National Park archive in Orick, CA. The earlier data sets (1973-1980) were collected by the USGS Forest Geomorphology Group based in Menlo Park, CA (Dr. Richard Janda, K. Michael Nolan, Deborah Harden, and James Duls). That office has since been dissolved and many of the original field notes are not available. The lengths of the longitudinal surveys varied slightly from year to year based on the starting point of the surveys and minor channel shifting. See respective metadata records for more details. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable. Original Data Collection and Processing: Cross sectional and longitudinal profile surveys were conducted from 1953-2017 (note that no surveys were conducted from 1954-1972) Original cross sectional survey data were analyzed by a custom Basic software program "WINSCOUR" which outputted cross section data into .SCR files. These files were later converted into .DAT files, one file for each survey. Original longitudinal profile survey data were analyzed by a custom Basic software program "LONGPRO" which outputted longitudinal profile data into .LPR data files. These files were later converted into .xlsx format. 1953 Mary Ann Madej U.S. Geological Survey, Western Ecological Research Center Scientist Emeritus mailing and physical

The selected subset was data that had the associated raw field data available and thus could be thoroughly quality controlled. Western Ecological Research Center (WERC) shared data files and project documents with the DaR team via Google Drive (cross sectional data were received as individual .DAT files and longitudinal profile data were received as individual .xlsx files) DaR team checked in data sets by ensuring that 10% of each folder (either cross section or longitudinal profile folder) opened successfully in Notepad (for cross sections) or Excel (for longitudinal profiles) Longitudinal profile data were consolidated into one spreadsheet in Microsoft Excel, saved as a CSV file and quality controlled (see Longitudinal Profile metadata record for details) A Python script was written by the DaR team to consolidate all cross sectional .DAT files into a CSV file, which was quality controlled (see Cross Sectional metadata record for details) Cross section GPS location spreadsheet was transformed into a shapefile (see Cross Sectional metadata record for details) All supplemental documents were included on the ScienceBase page (glossary, mid-channel graphic, field setting description, methodology description and data index document) 2018 Cristiana I Falvo U.S. Geological Survey, Fort Collins Science Center Technical Support mailing and physical

The shapefile describes the locations of all cross sections along Redwood Creek, however, the data from only some of these cross section locations were preserved in this release. Some additional cross sections were established due to lost cross section end points from landslides or for specific sub-projects and therefore may be labeled alphanumerically and/or located in close proximity.
