Let Φ ={φ (x): x∈ R2} be a Gaussian random field on the plane. For $A\subset {\Bbb R}^{2}$, we investigate the relationship between the σ-field F(Φ ,A)=σ {φ ...

We give an approach for using flow information from a system of wells to characterize hydrologic properties of an aquifer. In particular, we consider experiments where an impulse of tracer fluid is ...
