Realistische 3D-Simulation von Georadar-Daten im sedimentologischen Kontext
(2019)
In der Geophysik stellt die Modellierung synthetischer Referenzdatensätze eine wichtige
Grundlage sowohl für die Evaluation grundlegender Schritte der Datenbearbeitung als
auch für die Entwicklung neuartiger Ansätze zur ...
Estimating moisture changes in concrete using GPR velocity analysis: potential and limitations
(2018)
Chloride-induced corrosion of steel rebars is a key problem
for the durability and safety of reinforced concrete buildings
such as bridges. Penetrating rainwater transports the
chlorides into exposed parts of these ...
3D Classified GPR Facies Models From Multi-Frequency Data Volumes: A Synthetic Study
(2022)
Modern GPR systems allow for acquiring densely sampled data sets also using different antenna frequencies. Here, we consider such a multi-frequency approach to image near-surface sedimentary structures at different spatial ...
Risk of extreme high fatalities due to weather and climate hazards and its connection to large-scale climate variability
(
- Climatic Change
, 2020-09-08)
Weather and climate hazards cause too many fatalities each year. These weather and climate hazards are projected to increase in frequency and intensity due to global warming. Here, we use a disaster database to investigate ...
Geophysical methods help to assess potential groundwater extraction sitesGeophysikalische Methoden zur Bewertung potenzieller Standorte für die Grundwassergewinnung

, 2021-10-07)
Complex geology in glacial terrain makes groundwater exploration challenging for water supply companies. Abrupt lateral changes of geological conditions, for example, raise the risk of unsuccessful exploration drilling. ...
Revisiting climate change effects on winter chill in mountain oases of northern Oman
(
- Climatic Change
, 2020-10-07)
For centuries, traditional high-altitude oases in Oman have depended on the cultivation of deciduous fruit trees. This study explores the effects of climate change on winter chill (estimated as Chilling Hours—CH and Chill ...
Will dairy cattle production in West Africa be challenged by heat stress in the future?
(
- Climatic Change
, 2020-05-15)
This study focuses on heat stress conditions for dairy cattle production in West Africa under current and future climatic conditions. After testing the accuracy of the dynamically downscaled climate datasets for simulating ...
Regional gravity field refinement for (quasi-) geoid determination based on spherical radial basis functions in Colorado
(
- Journal of Geodesy
, 2020-10-10)
This study presents a solution of the ‘1 cm Geoid Experiment’ (Colorado Experiment) using spherical radial basis functions (SRBFs). As the only group using SRBFs among the fourteen participated institutions from all over ...
Combining 3D seismics, eyewitness accounts and numerical simulations to reconstruct the 1888 Ritter Island sector collapse and tsunami
(
- International Journal of Earth Sciences
, 2020-04-18)
The 1888 Ritter Island volcanic sector collapse triggered a regionally damaging tsunami. Historic eyewitness accounts allow the reconstruction of the arrival time, phase and height of the tsunami wave at multiple locations ...
GLONASS FDMA data for RTK positioning: a five-system analysis
(
- GPS Solutions
, 2020-10-24)
The use of the GLONASS legacy signals for real-time kinematic positioning is considered. Due to the FDMA multiplexing scheme, the conventional CDMA observation model has to be modified to restore the integer estimability ...
