Because hydraulic diffusivity is related to transmissivity and storativity, D = T/S, and the relationship between phase shift and hydraulic diffusivity can be written as follows: \begin{equation}p(z,\omega ) = B{K_u}\varepsilon (1 - {e^{ - (1 + i)z/\sqrt {2D/\omega } }})\end{equation}

Often, the impedance method is applied in the frequency domain: P ( s ) = Z ( s )Q( s ) (3) where Z(s) is impedance matrix of the hydraulic system. Substituting equation (1) and (2) into the Laplace transform, with zero initial conditions, the integrated system equations can be got: s 2 M + s ( C - R1 AZ ( s ) AR2 ) + K Y ( s ) = F2 ( s ) (4) The Sobol sensitivity analysis 3.1 Design variables How to select proper hydraulic …
