Pugh, A.L. Redman, R.K. 2019 NA - This is landing page for Ouachita data report. Data on child pages associated with this landing page Data Release U.S. Geological Survey http://dx.doi.org/10.5066/F7BC3WNX https://doi.org/10.3133/ds1104 Seventeen streamflow-gaging stations, operated by the U.S. Geological Survey and distributed across the Ouachita Mountains of Arkansas and Oklahoma were selected for analysis. Regional hydraulic geometry curves relating drainage area to bankfull dimensions -- cross-sectional area, top width, mean depth, and streamflow -- were developed from data collected at the selected streamflow-gaging stations. Bed material sampling was conducted to obtain information on the particle-size distributions of the streambed materials and to determine the shapes of the individual particles comprising the streambeds. The stream reaches at each stream gage location were classified using the Rosgen Level II stream type (Rosgen, 1996) based on the average of stream channel metrics collected from site cross-sections and profiles.

Child item contains data and supporting metadata related to: 1) Streamflow-gaging stations -- geospatial point shapefile of the 17 selected streamflow-gaging stations 2) Watersheds -- geospatial polygon shapefile of the watersheds above the 17 selected streamflow-gaging stations 3) Streambed particle data -- particle size and shape data collected at the 17 selected stream reaches 4) Site information and photos -- stream geometry, classification, descriptions and photos of the 17 selected stream reaches These data support the following publication: Pugh, A.L., and Redman, R.K., 2019, Regional hydraulic geometry characteristics of stream channels in the Ouachita Mountains of Arkansas: U.S. Geological Survey Data Series 1104, 25 p., https://doi.org/10.3133/ds1104. 2001 2016 publication date Complete None planned -94.633483886561 -91.837463378855 35.263204615158 34.229609065849 USGS Thesaurus Geomorphology Bankfull Hydraulic Geometry Regional Curves Stream Classification Bed-load USGS Metadata Identifier USGS:574f0f84e4b0ee97d51a859a Geographic Names Information System Arkansas Oklahoma Ouachita Mountains Big Fork Stream, AR Lewis Creek, AR Mountain Fork, OK Barnes Branch, AR Little Sugarloaf Creek, AR Jackson Creek, AR Glazypeau Creek, AR Rock Creek, AR Twomile Creek, AR Alum Fork Saline River, AR Kiamichi River, OK Little Missouri River, AR Cossatot River, AR Caddo River, AR Fouche LaFave River, AR Saline River, AR none none Aaron L.

No formal positional accuracy tests were conducted No formal positional accuracy tests were conducted Simply a list of child pages 2017 The Ouachita Mountains are located in west-central and central Arkansas and south-eastern Oklahoma, extending approximately 225 miles east to west from east of Little Rock, Arkansas, to Atoka, Oklahoma, and north to south, approximately 50-60 miles from the Arkansas River Valley to the northern margin of the West Gulf Coastal Plain. Physiographically, the Ouachitas are located within the Ouachita Mountains physiographic section (Fenneman, 1938). The Ouachita Mountains physiographic section generally aligns with the Ouachita Mountains - Level III U.S. Environmental Protection Agency (EPA) ecoregion (Omernik, 1987).
