Estimating mean annual streamflow of rural streams in Kentucky
G. R. Martin
2002, Water-Resources Investigations Report 2002-4206
Mean annual streamflow ( Q a ), defined as the mean of the series of annual mean streamflow values, was determined for selected rural stream sites in Kentucky. Streamflow data for the available period of record through the 1999 water year (October 1, 1998-September 30, 1999) at 235 continuous-record streamflow-gaging...
Occurrence of selected volatile organic compounds and soluble pesticides in Texas public water-supply source waters, 1999-2001
