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 ... -
Special Issue on Rock Fracturing and Fault Activation: Experiments and Models
(Rock Mechanics and Rock Engineering, 2021-09-27)This paper is the editoral of a special issue, that intends to summarize the highlights of the conference programme consisting of 8 keynote lectures, 47 oral presentations and 26 poster presentations given by rock mechanics ... -
Spontaneously Exsolved Free Gas During Major Storms as an Ephemeral Gas Source for Pockmark Formation
(Geochemistry, Geophysics, Geosystems, 2022-08-12)Abrupt fluid emissions from shallow marine sediments pose a threat to seafloor installations like wind farms and offshore cables. Quantifying such fluid emissions and linking pockmarks, the seafloor manifestations of fluid ... -
Stability assessment of marble statuaries of the Schlossbrücke (Berlin, Germany) based on rock strength measurements and ultrasonic wave velocities
(Environmental Earth Sciences, 2013)The degree of weathering in natural stones on buildings and sculptures has been determined for many years in numerous cases by means of ultrasonic measurements. Conclusions concerning the strength of the rock and the type ... -
Stability assessment of sandstones from the St. Servatius Church in Quedlinburg (UNESCO’s World Heritage Site, Germany)
(Environmental Earth Sciences, 2010)The St. Servatius Church in Quedlinburg (UNESCO’s World Heritage Site, Germany) is characterised by long-standing stability problems and structural damages, which have been known over the last several centuries. The ... -
Steine am Stolper Turm
(Neubrandenburger Geologische Beiträge, 2012-04-17)Der Turm zu Stolpe stellt das bedeutendste mittelalterliche Steinbauwerk des 12 Jh. in der nördlichen Uckermark dar. Es wurden zu seinem Bau neben dem Backstein sowohl vor Ort auffindbare Findlinge (skandinavische Geschiebe) ... -
Stochastic Modeling Approach to Identify Uncertainties of Karst Conduit Networks in Carbonate Aquifers
(Water Resources Research, 2022-08-09)The characterization of the karst conduit network is an essential task to understand the complex flow system within karst aquifers. However, this task is challenging and often associated with uncertainty. Equivalent porous ... -
Stochastische Grundwassermodellierung in der ingenieurtechnischen Praxis
(Sörensen, Hamburg, 1997)Analytische und numerische Modelle sind seit Jahrzehnten bewährte Hilfsmittel zur Berechnung von Strömungs- und Transportvorgängen im Grundwasser. Mit der Verfügbarkeit leistungsstarker Kleinrechner seit den 80er Jahren ... -
Strain Signals Governed by Frictional‐Elastoplastic Interaction of the Upper Plate and Shallow Subduction Megathrust Interface Over Seismic Cycles
(Tectonics, 2022-05-03)The behavior of the shallow portion of the subduction zone, which generates the largest earthquakes and devastating tsunamis, is still insufficiently constrained. Monitoring only a fraction of a single megathrust earthquake ... -
Strain-dependent slope stability
(Acta Geotechnica, 2020-05-09)The state of equilibrium of a slope is usually interpreted and expressed by safety factors based on calculations with limit equilibrium methods. Different stress states, failure modes and hydraulic conditions in sections ... -
Strategies for Simplifying Reactive Transport Models: A Bayesian Model Comparison
