Evaluating at Three Scales the Hydraulic Conductivity in an Unconfined and Stratified Alluvial Aquifer

What is it about?

The values of hydraulic conductivity K were evaluated at three scales in a stratified alluvial aquifer. The small scale is that of hundreds of soil samples for which K was estimated using predictive methods. The medium scale is that of hundreds of variable-head (slug) permeability tests in monitoring wells. The large scale is that of sixteen pumping tests in steady-state conditions. If the grain size distributions are correctly interpreted and the field permeability tests are correctly performed and interpreted, the distribution curves for the small-scale and medium-scale K values explain the large-scale K values of pumping tests, and there is no need to invoke any scale effect.
