Assuming that the \(ln\) hydraulic conductivity in an aquifer is mathematically approximated by a spatial deterministic ``surface'', or trend, plus a stationary random noise, we treat the problem of finding what the effective hydraulic conductivity of that aquifer is. This problem is tackled by spectral methods applied to a type of diffusion equation of groundwater flow, together with suitable coordinate transformations. Analytical (exact) solutions in terms of elementary functions are presented for one- and three-dimensional finite and infinite domains, and stability criteria are obtained.
