Topic	Sediment: V* by NCRWQCB, 1992

Caption:  The chart table "KNOPP_HUC12.DBF" contains values from Mattole Basin streams studied by Knopp in 1992. Data are provided by the North Coast Regional Water Quality Control Board. A V* of 50% indicates that half of the residual pool is filled with fine sediment. The values are averages of XX pools sampled (SE_V_STAR = standard error). See Info Links for more information. Use the "F7" key for viewing of the following caption descriptions: REACH = Reach number established by Knopp (1993) NAME = self explanatory COUNTY = self explanatory HUC = Hydrologic Unit Code number CATEGORY = disturbance category, Index Yes or No refer to historic management ACRES = self explanatory SLOPE = study reach slope in percent RASI = Riffle Armor Stability Index (see Knopp (1993) for more information) D50 = the diameter (mm) of the 50th percentile particle from three 200 pebble counts VSTAR = the proportion (%) of fine sediment in the residual pool WATER = the proportion (%) of water in the residual pool PNUM = the number of pools in a 1000m survey reach PFREQ = the total length (in meters) of pools in a 1000m reach COVVOL = wood cover divided by wood volume in percent WDCOV = the area (m^2) of wood cover in the 1000m reach WDSUBST = the area (m^2) of substrate change caused by wood in the 1000m reach WDVOL = = the volume (m^3) of wood cover in the 1000m reach S/V = substrate change divided by wood volume SEDEQL, SED123 = rapid sediment budget values from different algorithms.
