File "GRAB" contains the grab sample data and reg:ression <br /> <br />coefficients. USGS grab samples should be reforn~tted into the <br /> <br />USBR Grand Junction Project Office format and merged with the USBR <br /> <br />grab samples in chronological order. The TDS values should be <br /> <br />based on comparable methods of determination. For a given <br /> <br />project, a correlation between residue and sum of consitituents <br /> <br />can be found, and then used to convert all residue values to <br /> <br />equivalent sum of constituents values. It is felt that the sum of <br /> <br />constituents is the most reliable method. If all three flow, TDS, <br /> <br />and EC values are blank or zero, it is interpreted as a dry event. <br /> <br />Card Description of Variables <br /> <br />I Tit Ie <br /> <br />Format: (8AIO,n <br /> <br />3 BO,BI,B2,B3,B4,BS,TDSLO,TDSHI <br /> <br />Where: <br /> <br />BO,BI,B2,B3,B4,BS are regression coefficients in the <br /> <br />following equations: <br /> <br />TOS = BO*EC+BI for summer <br /> <br />TOS = B4*EC+BS for winter <br /> <br />TOS = B2*FL**B3 <br /> <br />A-9 <br />
