<br />To avoid confusion due to the use of the same symbol for the <br /> <br />dimension time as for the coefficient of transmissibility, symbols for <br /> <br />the dimensions time and length are in Roman capitals and enclosed in <br /> <br />brackets. All other symbols, except that designating the mathematical <br /> <br />term, second repeated integral, are in italics. <br /> <br />The dimensions of T, t, Q, ~, ::.' and..! used in the sample <br /> <br />computations are specified where necessary. <br /> <br />Stream, depletion means either direct depletion from the stream <br /> <br />or reduction of return flow to the stream. <br /> <br />The curves and tables in this report are dimensionless, and can <br /> <br />" <br />I. <br /> <br />be used with any dimensional system. The units in the system must <br /> <br />be consistent, however. For example, if !l and q are in acre-ft/day <br /> <br />I.. <br /> <br />(acre-feet per day), ::!- must be in acre-ft (acre-feet). If a is in ft <br /> <br />(feet), and T/S is in gal/day-ft (gallons per day per foot), <br />- - <br /> <br />the value of T/S must be converted to fta/day (square feet per day). <br />- - <br />.l3 .l3 ~ I fe \ <br />A T/S value of Iv gal/day-ft equals (Iv gal/day-ft) 7.48 gall equals <br /> <br />133,700 fta /day. <br /> <br />.' <br /> <br />"0 . <br />'9.9 <br /> <br /> <br />6 <br />
