Simulation of direct shear tests using a forces on fracture surfaces (FFS) approach
(Environmental Earth Sciences, 2021-04-07)The aim of this work is to provide a complete data set of direct shear tests and to propose a corresponding simulation approach. Tests have been conducted on crystalline rock samples applying constant normal load (CNL) and ... -
Simulation of saturated and unsaturated flow in karst systems at catchment scale using a double continuum approach
(Hydrology and Earth System Sciences, 2012-10-30)The objective of this work is the simulation of saturated and unsaturated flow in a karstified aquifer using a double continuum approach. The HydroGeoSphere code ( Therrien et al. , 2006 ) is employed to simulate spring ... -
Site Dependence of Fluvial Incision Rate Scaling With Timescale
(Journal of Geophysical Research: Earth Surface, 2020-10-26)Global measurements of incision rate typically show a negative scaling with the timescale over which they were averaged, a phenomenon referred to as the “Sadler effect.” This time dependency is thought to result from hiatus ... -
Size–frequency distribution of shallow landslides in the Black Forest, Germany
(Earth Surface Processes and Landforms, 2021-10-09)Landslides are a major hazard in mountainous regions, represent a threat to human life, and cause substantial economic costs. While some landslide hazard assessments, including hazards maps, are available for Germany, their ... -
Slab break-offs in the Alpine subduction zone
(International Journal of Earth Sciences, 2020-01-30)After the onset of plate collision in the Alps, at 32–34 Ma, the deep structure of the orogen is inferred to have changed dramatically: European plate break-offs in various places of the Alpine arc, as well as a possible ... -
Slip Rate of the Danghe Nan Shan Thrust Fault from 10Be Exposure Dating of Folded River Terraces: Implications for the Strain Distribution in Northern Tibet
(Tectonics, 2021-03-23)The northeastward motion of the Tibetan Plateau along the Altyn Tagh strike‐slip fault causes thrust faulting in three parallel mountain ranges (Qilian Shan, Daxue Shan, and Danghe Nan Shan) in the plateau interior, and ... -
Small scale controls of greenhouse gas release under elevated N deposition rates in a restoring peat bog in NW Germany
(Biogeosciences, 2008)In Central Europe, most bogs have a history of drainage and many of them are currently being restored. Success of restoration as well as greenhouse gas exchange of these bogs is influenced by environmental stress ... -
Small scale spatial heterogeneity of soil respiration in an old growth temperate deciduous forest
(Biogeosciences Discussions, 2009) -
Snowmobile impacts on snowpack physical and mechanical properties
(The Cryosphere, 2018)Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different ... -
Spalten auf Island - geologische, geodätische und geophysikalische Forschungsarbeiten der deutschen Island-Expedition des Jahres 1938
(Wittwer, Stuttgart, 1943)In der geologischen Kritik der bestehenden Erdsynthesen nehmen die Probleme des Zusammenhanges von Horizontal- und Vertikal-Tektonik einen breiten Raum ein…

Spatial analysis of loess and loess-like sediments in the Weser- Aller catchment (Lower Saxony and Northern Hesse, NW Germany)
(Quarernary Science Journal, 2011) -
Spatial analysis of loess and loess-like sediments in the Weser-Aller catchment (Lower Saxony and Northern Hesse, NW Germany)
(E&G – Quaternary Science Journal; Vol.60, No. 1)Eine räumliche Kompilation und Darstellung von Löss-Parametern wurde für die pleistozänen Lösse und löss-ähnlichen Sedimente im Weser-Aller-Einzugsgebiet (Süd-Niedersachsen und Nordhessen, NW-Deutschland), einer der ... -
Spatial and temporal dynamics of aufeis in the Tso Moriri basin, eastern Ladakh, India
(Permafrost and Periglacial Processes, 2022-10-12)Aufeis is a common phenomenon in cold regions of the Northern Hemisphere that develops during winter by successive water overflow and freezing on ice‐covered surfaces. Most studies on aufeis occurrence focus on regions in ... -
Spatial Markov Model for the Prediction of Travel‐Time‐Based Solute Dispersion in Three‐Dimensional Heterogeneous Media
(Water Resources Research, 2022-06-13)In recent years, Spatial Markov Models have gained popularity in simulating solute transport in heterogeneous formations. They describe the transition times of particles between equidistant observation planes by statistical ... -
Spatial variability in river bed porosity determined by nuclear density gauging: A case study from a French gravel‐bed river
(Sedimentology, 2021-09-16)Porosity is one of the key properties of fluvial sediments. It is defined as the ratio of pore volume to total volume. In river science, porosity is often assumed to be spatially constant, which might be a gross simplification ... -
