<br />\, <br /> <br />ABSTRACT <br /> <br />The effects on flow of a nearby stream from pumping a well can <br /> <br />I <br /> <br />be calculated readily using dlinensionless curves and tables. <br /> <br />Computations can be made of: (1) The rate of stream depletion at any <br /> <br />time during the pumping period or after the cessation of pumping; (2) <br /> <br />The volume induced from the stream during any time, both during <br /> <br />pumping or after the cessation of pumping; and (3) <br /> <br />The effects, both <br /> <br />in rate and volume of stream depletion, of any selected pattern of <br /> <br />intermittent pumping. Sample computations illustrate the use of the <br /> <br />curves and tables. An example shows that intermittent pumping may <br /> <br />have a pattern of stream depletion not greatly different froll a <br /> <br />\ <br />) <br />.~ <br /> <br />pattern for steady pumping of an equal volume. <br /> <br />The residual effects of pumping, that is, effects after cessation <br /> <br />of pumping, on streamflow may easily be greater than the effects <br /> <br />during the pumping period. Adequate advance planning that includes <br /> <br />consideration of residual effects thus is essential to effective <br /> <br />administration of a stream-aquifer system. <br /> <br />././0. <br />1 <br /> <br />- <br />\ <br /> <br />I <br /> <br />- <br /> <br />" <br /> <br />
