Geoelectrical monitoring: an innovative method to supplement landslide surveillance and early warning
Robert Supper,David Ottowitz,Birgit Jochum,Jung-Ho Kim,A. Römer,Ivo Baron,Stefan Pfeiler,Mario Lovisolo,S. Gruber,Filippo Vecchiotti +9 more
TL;DR: In this article, permanent geoelectrical monitoring, using the GEOMON4D instrumentation in combination with high resolution displacement monitoring by means of the D.M.S. system, was performed at two active landslide areas: Ampflwang/Hausruck in Austria, and Bagnaschino in Italy.

Geoelectrical monitoring of frozen ground and permafrost in alpine areas: field studies and considerations towards an improved measuring technology
Robert Supper,David Ottowitz,Birgit Jochum,A. Römer,Stefan Pfeiler,S. Gruber,Markus Keuschnig,Anna Ita +7 more
TL;DR: In this paper, an improved data acquisition system for geoelectrical monitoring of frozen soils was developed based on the results of several test studies, and the implementation of algorithms for statistical analysis of raw data time series led to a significant improvement in the reliability of inversion results.

Spatial mapping of submerged cave systems by means of airborne electromagnetics: an emerging technology to support protection of endangered karst aquifers
Robert Supper,Klaus Motschka,Andreas Ahl,Peter Bauer-Gottwein,Bibi Ruth Neuman Gondwe,Gonzalo Merediz Alonso,A. Römer,David Ottowitz,Wolfgang Kinzelbach +8 more
TL;DR: In this article, an international scientific research project was initiated to explore the potential of airborne electromagnetic mapping for providing such innovative information for improving groundwater modelling of karst aquifers, where ground geoelectric and ground electromagnetic measurements were performed in March 2006 to determine the electrical properties of the Sian Ka'an Biosphere Reserve subsurface environment.

A method for the stochastic modeling of karstic systems accounting for geophysical data: an example of application in the region of Tulum, Yucatan Peninsula (Mexico)
Cécile Vuilleumier,Andrea Borghi,Philippe Renard,David Ottowitz,A. Schiller,Robert Supper,Fabien Cornaton +6 more
TL;DR: In this article, a stochastic pseudo-genetic karst simulator is used to estimate the velocities in karstic conduits in the Yucatan aquifer.
Water content dynamics at plot scale - comparison of time-lapse electrical resistivity tomography monitoring and pore pressure modelling
Thomas Zieher,Thomas Zieher,Gerhard Markart,David Ottowitz,A. Römer,Martin Rutzinger,Gertraud Meißl,Clemens Geitner +7 more
TL;DR: In this article, the results of a spray irrigation experiment conducted on a plot of 100m2 on an Alpine slope susceptible to shallow landsliding are presented. But the applicability of physically-based models is only rarely tested in the field at the appropriate scale.
