Case 2 <br /> <br />1) Daily Data Available: Flow and EC <br /> <br />2) Grab Sample Interval: GSI > MAXILO <br /> <br />3) Method: Input today' s EC into the input TDS-;;:C linear <br /> <br />regression. Again, loading is simply the pro.iuct of the <br /> <br />daily flow, TDS, and the conversion factor. <br /> <br />D. Case 3 <br /> <br />1) Daily Data Available: flow only <br /> <br />2) Grab Sample Interval: GSI < MAXIHI <br /> <br />3) Method: Calculate the loading on the days of the 2 <br /> <br />bordering grab samples using the TDS and flow of th~se <br /> <br />samples. Then linearly interpolate (wrt. time) between <br /> <br />those 2 loadings to estimate today's loading. Then divide <br /> <br />the loading by the daily flow and the conversion factor to <br /> <br />get the TDS. <br /> <br />E. Case 4 <br /> <br />1) Daily Data Available: flow only <br /> <br />2) Grab Sample Interval: GSI > MAXIHI <br /> <br />3) Method: Use the input TDS-flow power regression with <br /> <br />today's flow to estimate this day's TDS, and Inult iply by the <br /> <br />flow and the conversion factor to get the day's loading. <br /> <br />A-4 <br />
