Year-round variability of field-saturated hydraulic conductivity and runoff in tilled and grassed vineyards [PDF]

open access: yes, 2017
The soil management adopted in vineyard inter-rows has a great influence on soil hydraulic properties, and, consequently, on runoff at the field scale.

A Bayesian Consistent Dual Ensemble Kalman Filter for State-Parameter Estimation in Subsurface Hydrology [PDF]

open access: yes, 2015
Ensemble Kalman filtering (EnKF) is an efficient approach to addressing uncertainties in subsurface groundwater models. The EnKF sequentially integrates field data into simulation models to obtain a better characterization of the model's state and ...

Hydraulic conductivity of rock fractures [PDF]

open access: yesTransport in Porous Media, 1996
The flow of a single-phase fluid through a rough-walled rock fracture is discussed within the context of fluid mechanics. The derivation of the ‘cubic law’ is given as the solution to the Navier-Stokes equations for flow between smooth, parallel plates - the only fracture geometry that is amenable to exact treatment. The various geometric and kinematic

Characterization of stony soils' hydraulic conductivity using laboratory and numerical experiments [PDF]

open access: yesSOIL, 2016
Determining soil hydraulic properties is of major concern in various fields of study. Although stony soils are widespread across the globe, most studies deal with gravel-free soils, so that the literature describing the impact of stones on the hydraulic ...
