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.

Electrical resistivity tomography technique for landslide investigation: A review
TL;DR: A review of the main results obtained by applying 2D and 3D Electrical Resistivity Tomography (ERT) for the investigation of a wide spectrum of landslide phenomena which affected various geological formations and occurred in different geographic areas is presented in this paper.

Geophysical Monitoring of Moisture-Induced Landslides: A Review
J. Whiteley,J. Whiteley,Jonathan Chambers,Sebastian Uhlemann,Paul Wilkinson,J-Michael Kendall +5 more
TL;DR: Whiteley et al. as discussed by the authors presented a review of the state of the art of geophysical monitoring applied to moisture-induced landslides, focusing on technical and practical uses of time-lapse methods in geophysics applied to monitoring moistureinduced landslide.
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.

Geophysical survey to estimate the 3D sliding surface and the 4D evolution of the water pressure on part of a deep seated landslide
TL;DR: In this paper, an electrical resistivity survey was carried out to obtain, for the first time on this deep-seated landslide, 3D information on the slipping surface and the vertical drained faults.

Julien Travelletti,Julien Travelletti,Pascal Sailhac,Jean-Philippe Malet,Gilles Grandjean,J. Ponton +5 more
TL;DR: In this paper, an attempt to monitor water infiltration and subsurface flow within a clay-shale landslide using time-lapse electrical resistivity tomography (ERT) is presented.

Practical aspects of applied optimized survey design for electrical resistivity tomography
Paul Wilkinson,M.H. Loke,Philip Meldrum,Jonathan Chambers,Oliver Kuras,David Gunn,Richard Ogilvy +6 more
TL;DR: In this paper, a simulated annealing algorithm is used to rearrange the optimised measurement sequences to minimise polarisation errors, and an optimisation algorithm is developed to design surveys by successive addition of multi-channel groups of measurements rather than individual electrode configurations, which produces results nearly as close to optimal as equivalent single channel surveys, while reducing data collection times by an order of magnitude.

A salt tracer test monitored with surface ERT to detect preferential flow and transport paths in fractured/karstified limestones
TL;DR: In this article, a tracer test monitored with surface electrical resistivity tomography (ERT) could help by delineating such preferential flow paths and estimating dynamic properties of the aquifer, but the lower resolution of surface ERT compared with crosshole ERT, the finite time that is needed to complete an entire data acquisition, and the strong dilution effects.

A saline tracer test monitored via both surface and cross-borehole electrical resistivity tomography: Comparison of time-lapse results
TL;DR: In this paper, the results of a saline tracer test experiment performed in the saturated zone at the water works facility at Valdobbiadene (Treviso, North-East Italy), where an alluvial phreatic aquifer is heavily exploited for irrigation and drinking water supply.
