Intensive Stream Survey Geomorphology Data from 2010 to 2011 at the Coweeta Hydrologic Laboratory, Otto, NC

From June 2010 until February 2011, fifty streams were surveyed to determine the physical characteristics of streams in forested, traditional land use, and developed settings. Cross-sectional measurements were taken at 16 cross-sections on each reach. The distance between each cross-section was twice the average active channel width (which was determined prior to the survey). At one to three locations within each surveyed reach, slope was determined by placing a laser level at a location upstream and then measuring the amount of elevation change at the water surface. Between each cross-section, the instream habitat was recorded. Large woody debris was measured where it was found within the surveyed reach of the stream. Only LWD with diameter >10 cm was measured. At a representative riffle within the reach, a Wolman pebble count (100 randomly selected pieces of sediment) was taken.
