On the spatio-temporal dynamics of soil moisture at the field scale
Harry Vereecken,Johan Alexander Huisman,Yakov Pachepsky,Carsten Montzka,J. van der Kruk,Heye Bogena,Lutz Weihermüller,Michael Herbst,Gonzalo Martinez,Jan Vanderborght +9 more
TL;DR: In this paper, the authors review the state of the art of characterizing and analyzing spatio-temporal dynamics of soil moisture content at the field scale and discuss measurement techniques that have become available in recent years and that provide unique opportunities to characterize field scale soil moisture variability with high spatial and temporal resolution.

Journal ArticleDOI
Life and death of slow-moving landslides
TL;DR: In the most destructive and catastrophic landslide events, rocks, soil and fluids can travel at speeds approaching several tens of metres per second as discussed by the authors, but slow-moving landslides rarely claim lives, they can cause major damage to infrastructure and sometimes fail catastrophically, transitioning into fast moving landslides that can result in thousands of casualties.

Torleif Dahlin,Bing Zhou +1 more
TL;DR: In this article, numerical simulations are used to compare the resolution and efficiency of 2D resistivity imaging surveys for 10 electrode arrays, including pole-pole (PP), pole-dipole (PD), half-Wenner (HW), Wenner-α (WN), Schlumberger (SC), dipole-dipsole (DD), WenNER-β (WB), γ -array (GM), multiple or moving gradient array (GD) and midpoint-potential-referred measurement (MPR) arrays.

Practical techniques for 3D resistivity surveys and data inversion1
M.H. Loke,R. D. Barker +1 more
TL;DR: In this article, a smoothing-constrained least-squares inversion method is used for the data interpretation and the computing time required by this technique is greatly reduced by using a homogeneous half-space as the starting model so that the Jacobian matrix of partial derivatives can be calculated analytically.

DC Resistivity and Induced Polarization Methods
Andrew Binley,Andreas Kemna +1 more
TL;DR: In this paper, the relationship between direct current resistivity and hydrological properties, such as porosity and moisture content, is investigated. But the applications of induced polarization methods in hydrogeophysics have been limited.

Dennis L. Corwin,Scott M. Lesch +1 more
TL;DR: In this paper, a general overview of the application of soil electrical conductivity (EC) to precision agriculture is presented, with particular emphasis on spatial EC measurements: a brief history of the measurement of soil salinity with EC, the basic theories and principles of the soil EC measurement and what it actually measures, examples of spatial EC surveys and their interpretation, applications and value of spatial measurements of soil EC, and current and future developments.
