Glover* <br /> <br />Introduction <br /> <br />r, <br /> <br />II <br /> <br />Water resources have commonly been considered as falling within one of <br />two separate and distinct categories. T,1ese are surface waters and ground <br />waters. As our water supplies are becoming more heavily encumbered. it is <br />beginning to be realized 'lOwever, that these two categories are not necessarily <br />distinct; and that in irrigation practice. the operations of tne surface diverter <br />and the user of ground water may affect each other in very fundamental and <br />important ways. Such possibilities may be broug'1t to attention. for example, <br />by the advent of pumping in an area previously irrigated by surface diversion <br />alone. <br /> <br />I <br />!' <br /> <br />I <br />I <br />:1 ..' <br /> <br />.- <br /> <br />The possibility tllat an established surface diversion right might be adversely <br />affected by pumping operations has led to demands for legal regulation of the <br />pumps. However efforts to frame an equitable ground water law ,lave run into <br />trouble because of the difficulty of evaluating the nature and magnitude of the sup- <br />posed interferences. Before these relationsnips can be clarified it will be neces- <br />sary to evaluate quantitatively the effects of storage and release of ground <br />water. It is the purpose of t>-lis paper to describe an analytical procedure by <br />which these evaluations can be made. <br /> <br />Ii <br /> <br />" <br /> <br />Analytical methods <br /> <br />The procedures to be described are an outgrowth of the mathematical <br />methods discovered by Isaac Newton in about the year 1666. (8) Of particular <br />importance are the additional developments of J. B.J. Fourier about 1812.. (l) <br />It was in this year that Fourier's methods were presented to the French Academy <br />and stirred up one of the most violent controversies in the history of science. <br />The importance of this in the present connection is that if the budgetary require- <br />ment that the rate of rise of the water table within a narrow zone be compatible <br /> <br />Prepared for Western Resources Conference <br />Boulder, Colorado <br />Augus t 1960 <br />Paper CER60REG45 <br /> <br />* Engr.
