Topic	Sediment: V* by NCRWQCB, 1992 & 1993

Caption:  The chart table "Knopp_Vstar_Mattole.DBF" contains V* values from the Mattole Basin. 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). Data are provided by the North Coast Regional Water Quality Control Board. 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 See Info Links for more information.
