<br />Which, given a saturated thickness of 11.9 feet, gives a hydraulic conductivity <br />of 0.5 cm/day. <br />This value is in reasonable agreement with the results of the first analyses <br />(U,S, Navy Method). <br />The Cooper, Bredehoeft and Papadopulos methodology also gives a method of <br />solving for S (storage coefficient) S = r 2 <br />c °< <br />_~ <br />r <br />s <br />Where: o~ = curve number <br />rc = casing radius <br />r = hole radius <br />s <br />LJ <br />This results in a value of S = 0,1, a value which is crude since it depends <br />upon how well the data from a particular test match one of only several <br />curves. However, this value is in reasonable agreement with porosity values <br />for similar conditions (Walton ,1970). <br />The testing at alluvi.31 Well GWS-33 proceeded very smoothly, Solid casing <br />extended almost to the water table so that the head change correlated directly <br />with a known loss of water volume to the alluvium. Also, because of the <br />proximity of the water table to the ground surface and the fineness of the <br />material, the capillary fringe extended up to, or close to the ground surface. <br />Because of this, no presoaking was necessary to get stabilized values, as <br />several slug repetitions demonstrated, <br />The test results were analyzed according to the formula <br />K = Rz <br />• <br />2L(tz-tl) <br />h <br />l n( R) l n( hl ) <br />2 <br />i -'~-27 <br />
