Residual (28-30-8) <br /> <br />Column 30. The drain base flow is the ground-water leaving the basin by the <br />outflow drain. It is found by our base flow separation technique. The <br />summer base flow was then redistributed to a more reasonable hydrograph. <br /> <br />The gross budget provides the tons of salt pickup and the, base flow <br />separation provides an initial figure for the ground-wate,r volume. Taking <br />tons/A.F. of ground-water gives us a "loading factor" for the basin. If we <br />assume that the "loading factor" remains constant after construction, we can <br />find post salt loading by the following equation. <br /> <br />Post Outflow TDS = Factor+[Inflow TDS] outflow volume <br />inflow volume-C.U. <br /> <br />We will be able to define all the items on the right. <br /> <br />The internal budget provides the apportionment of the various ground-water <br />sources and provides us the information to evaluate alternatives. Defining <br />the items in the internal budget is an iterative process. The system of <br />programs that we've developed enable us to make changes relatively easily. <br />
