Cone penetration tests in dry and saturated Ticino sand
(
- Bulletin of Engineering Geology and the Environment
, 2021-03-11)
It is commonly assumed that dry and saturated sands exhibit similar cone resistance–relative density relationships. Some studies pointed out that partial saturation and calcareous sands with considerable fines content are ...
Depositional setting and limiting factors of early Late Cretaceous glaucony formation: implications from Cenomanian glauconitic strata (Elbtal Group, Germany)
(
- Facies
, 2021-06-14)
Cenomanian strata of the Elbtal Group (Saxony, eastern Germany) reflect a major global sea-level rise and contain, in certain intervals, a green authigenic clay mineral in abundance. Based on the integrated study of five ...
The June 2020 Aniangzhai landslide in Sichuan Province, Southwest China: slope instability analysis from radar and optical satellite remote sensing data
(
- Landslides
, 2021-11-29)
A large, deep-seated ancient landslide was partially reactivated on 17 June 2020 close to the Aniangzhai village of Danba County in Sichuan Province of Southwest China. It was initiated by undercutting of the toe of this ...
Emulator-based global sensitivity analysis for flow-like landslide run-out models
(
- Landslides
, 2021-08-13)
Landslide run-out modeling involves various uncertainties originating from model input data. It is therefore desirable to assess the model’s sensitivity to these uncertain inputs. A global sensitivity analysis that is ...
Linking gas and particle ejection dynamics to boundary conditions in scaled shock-tube experiments
(
- Bulletin of Volcanology
, 2021-07-20)
Predicting the onset, style and duration of explosive volcanic eruptions remains a great challenge. While the fundamental underlying processes are thought to be known, a clear correlation between eruptive features observable ...
Current and future state of groundwater salinization of the northern Elbe-Weser region
(
- Grundwasser
, 2021-11-11)
Salinization of the upper aquifer of the northern Elbe-Weser region almost extends to the surface. Chloride content exceeds 250 mg/l and the groundwater is therefore, according to the German Drinking Water Ordinance, not ...
Jenseits von Sichardt – empirische Formeln zur Bestimmung der Absenkreichweite eines Brunnens und ein Verbesserungsvorschlag
(
- Grundwasser
, 2021-12-09)
Die Kenntnis der Absenkreichweite eines Brunnens ist eine für viele Anwendungen in der Hydrogeologie wichtige, aber nicht immer einfach zu bestimmende Größe. Häufig werden daher empirische Formeln zur Berechnung genutzt, ...
Geologische, hydrogeologische und anthropogene Einflüsse auf die Wasserchemie der Möhlin, Schwarzwald – eine Momentaufnahme
(
- Grundwasser
, 2021-02-22)
Diese Arbeit untersucht die geologischen, hydrogeologischen und anthropogenen Einflüsse auf die chemische Zusammensetzung eines Flusses, am Beispiel der Möhlin. Wasserproben wurden an verschiedenen Flussabschnitten genommen ...
Coastal groundwater systems: mapping chloride distribution from borehole and geophysical data
(
- Grundwasser
, 2021-01-21)
Information on chloride (Cl) distribution in aquifers is essential for planning and management of coastal zone groundwater resources as well as for simulation and validation of density-driven groundwater models. We developed ...
Local radon flux maxima in the quaternary sediments of Schleswig–Holstein (Germany)
(
- International Journal of Earth Sciences
, 2021-04-23)
This paper presents radon flux profiles from four regions in Schleswig–Holstein (Northern Germany). Three of these regions are located over deep-rooted tectonic faults or salt diapirs and one is in an area without any ...
