A Ratio Method is presented, which dispenses with the classical curve-matching procedure for computing characteristics of Ideal, Leaky and Bounded aquifers. This simple method consists of selecting any three values of observed drawdown, (t0, s0), (t1, s1) and (t2, S2), such that t1= 2 t0and t2= 100 t0. Then, using the ratios, s0/s1and s0/s2, the values of u0, W(u0)as well as r/B (in the case of leaky aquifers) and ri(in the case of aquifers with one boundary) are extrapolated from the charts presented. The extrapolated values are substituted in the standard equations to determine the aquifer characteristics. The Ratio Method may also have useful application in other branches of science where the curve-matching procedure is employed for calculation of parameters.
