Aspects of pelagic sedimentation in the Devonian of Western Europe
(Reading : Geological Institute, 1971)During the Devonian of the Rhenich geosyncline (sediments exposed in the Rheinisches Schiefergebirge and Harz Mountains, Central Germany) condensed pelagic limestones, locally rich in cephalopods (Cephalopodenkalk), ... -
Assessing the utility of trace and rare earth elements as biosignatures in microbial iron oxyhydroxides
(Frontiers in Earth Science, 2015)Microbial iron oxyhydroxides are common deposits in natural waters, recent sediments, and mine drainage systems. Along with these minerals, trace and rare earth elements (TREE) are being accumulated within the mineralizing ... -
Assessment of the heterogeneity of hydraulic properties in gravelly outwash plains: a regionally scaled sedimentological analysis in the Munich gravel plain, Germany
(Hydrogeology Journal, 2020-08-11)The favorable overall conditions for the utilization of groundwater in fluvioglacial aquifers are impacted by significant heterogeneity in the hydraulic conductivity, which is related to small-scale facies changes. Knowledge ... -
Atmospheric CO2 fertilization effects on biomass yields of 10 crops in northern Germany
(Frontiers in Environmental Science, 2015)The quality and quantity of the influence that atmospheric CO2 has on crop growth is still a matter of debate. This study's aim is to estimate if [CO2] will have an effect on biomass yields at all, to quantify and spatially ... -
Atmospheric Ionic Deposition in Tropical Sites of Central Sulawesi Determined by Ion Exchange Resin Collectors and Bulk Water Collector
(Water, Air, & Soil Pollution, 2012)In the light of global change, the necessity to monitor atmospheric depositions that have relevant effects on ecosystems is ever increasing particularly for tropical sites. For this study, atmospheric ionic depositions ... -
Aufbau und Betrieb einer Virtuellen Fachbibliothek am Beispiel des Geo- und Montanwissenschaftlichen Portals GEO-LEO
(Bibliothek : Forschung und Praxis, 2007)Die Virtuelle Fachbibliothek GEO-LEO bietet Geo- und Montanwissenschaftlern eine integrierte Suche über Bibliothekskataloge, Literatur-Datenbanken und Volltextserver. Die Sondersammelgebietsbibliotheken in Freiberg und ... -
Auswertung von Pumpversuchen mit computergestützten Verfahren, Version 1.1.
(2008-07-21)Die Durchführung und Auswertung hydraulischer Pumpversuche sind Standardaufgaben in der Hydrogeologie bzw. Grundwasserhydraulik. In den vergangenen 20 Jahren hat sich der Einsatz von computergestützen Verfahren zur Auswertung ... -
Authors’ Reply to the Discussion by Crisci et al. (2021) on “Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions Mechanical Properties and the Influence of Rock Fabric”
(Rock Mechanics and Rock Engineering, 2021-11-02)This is a repond to the comments raised in Crisci´s et al. paper “Discussion on “Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions ¬ Mechanical Properties and the Influence of Rock ... -
Automated digital data acquisition for landslide inventories
(Landslides, 2020-06-11)Landslide research relies on landslide inventories for a multitude of spatial, temporal, or process analyses. Generally, it takes high effort to populate a landslide inventory with relevant data. In this context, the present ... -
Automated facies identification by Direct Push‐based sensing methods (CPT, HPT) and multivariate linear discriminant analysis to decipher geomorphological changes and storm surge impact on a medieval coastal landscape
(Earth Surface Processes and Landforms, 2021-09-23)In ad 1362, a major storm surge drowned wide areas of cultivated medieval marshland along the north‐western coast of Germany and turned them into tidal flats. This study presents a new methodological approach for the ... -
AVISA: anisotropic visco-ISA model and its performance at cyclic loading
(Acta Geotechnica, 2020-02-19)In this work, a constitutive model able to capture the strain rate dependency, small strain effects and the inherent anisotropy is proposed considering the influence of the overconsolidation ratio (OCR). Small strain effects ... -
Bau und Entstehung der Alpen
(Verlag von Gebrüder Borntraeger, Berlin, 1923)Es wird hier der Versuch gemacht, die wesentlichen neuen Erfahrungen über den Bau und Entstehung der Alpen zusammenzufassen. Im Laufe von 12 Sommern habe ich Gelegenheit gehabt, die Alpen vom Simplon bis in die Karpathen, ... -
Bayesian Calibration and Sensitivity Analysis for a Karst Aquifer Model Using Active Subspaces
(Water Resources Research, 2019)In this article, we perform a parameter study for a recently developed karst hydrological model. The study consists of a high-dimensional Bayesian inverse problem and a global sensitivity analysis. For the first time in ... -
Bayesian Calibration and Validation of a Large‐Scale and Time‐Demanding Sediment Transport Model
(Water Resources Research, 2020-07-24)This study suggests a stochastic Bayesian approach for calibrating and validating morphodynamic sediment transport models and for quantifying parametric uncertainties in order to alleviate limitations of conventional ... -
Bayesian geomorphology
(Earth Surface Processes and Landforms, 2020)The rapidly growing amount and diversity of data are confronting us more than ever with the need to make informed predictions under uncertainty. The adverse impacts of climate change and natural hazards also motivate our ... -
Bayesian Quantification and Reduction of Uncertainties in 3D Geomechanical‐Numerical Models
(Journal of Geophysical Research: Solid Earth, 2022-12-29)The distance to failure of the upper crustal rock in the prevalent stress field is of importance to better understand fault reactivation by natural and induced processes as well as to plan and manage georeservoirs. In ... -
