TL;DR: This article shows how equivalence is defined by using a criterion of flow or of the energy dissipated by viscous forces and explains the two different concepts of effective permeability and block permeability.

TL;DR: In this paper, a large-scale investigation of fracture flow was conducted in a granite uranium mine at Fanay-Augeres, France, and four types of data were collected: (1) geometry of the fracture network; (2) local hydraulic properties measured by injection tests in boreholes; (3) global hydraulic behavior from flow rate and piezometric head distribution at a 106 m3 scale; and (4) tracer tests performed at a scale of up to 40 m.

TL;DR: For the special case of a stratified porous medium with flow parallel to the bedding, it is shown that the transport of solute cannot, in general, be represented by the usual convection-diffusion equation, even for large time as discussed by the authors.

TL;DR: In this article, the authors compared seven different inverse approaches for identifying aquifer transmissivity and found that the linearized methods were more accurate than those of nonlinear methods in predicting travel times and travel paths.

TL;DR: In this paper, the results of the tracer experiments are interpreted and a particle following coupled to the flow model, described in paper 1, is used to confirm the validity of the preliminary hydraulic calibration of the model and to validate further the approach used to simulate hydraulic and transport phenomena.
