The radius of influence . approach was shown not to be a good design parameter for well spacing or determining the number of wells by Cho and DiGiulio 1992 , who performed pneumatic pump tests . WebR = radius of influence [m] Tr = transmissivity [m^2/s] t = time [s] S = storage. h = height of the water table above substratum [m] n = effective porosity. Ksat = saturated hydraulic conductivity [m/s] s = drawdown in the borehole [m] These inputs can be single numbers or vectors of equal length.
