Brad input the new depletion data <br />and in order to preserve the 50% depletion rate, when he went In to increase the <br />depletion to 120.000 AF. he also increased the diversion to 240.000 AF, which <br />created a corresponding increase in the return flow volume (there was no change in <br />the return flow concentration). Note the dramatic increase in the resultant river <br />salinity concentration and the total tons in the river. <br /> <br />Up Stream <br /> <br />River Flow: 500,000 AF <br />River Concentration: 550 mgll <br /> <br />Diversion to User X <br />Depletion <br />Diversion Rate <br />Diversion Concentration <br /> <br />Return Flow Volume <br />Salt Pickup <br /> <br />Concentratina Effect <br /> <br />(The concentrating effect is equal to the diversion <br />concentration multiplied by the ratio of the <br />diversion volume to the return flow volume.) <br /> <br />Return Flow Concentration: <br /> <br />1,100 mgll+ <br /> <br />Return Flow Concentration <br />Return Flow Volume <br /> <br />Down Stream <br />River Flow: <br />River Concentration: <br /> <br />120,000 AF <br />240,000 AF <br />550 mg/l <br /> <br />120,000 AF <br />700 mgll <br /> <br />= <br /> <br />1,100 mgll <br /> <br />700 mg/l <br /> <br />= 1.800 m II <br />120.000 AF <br /> <br />380.000 AF <br />945 mgJI <br />488.435 tons <br /> <br /> <br /> <br />J <br />~ <br />N <br />~ <br /> <br />
