Investigations into the opening of fractures during hydraulic testing using a hybrid-dimensional flow formulation
; ; (Environmental Earth Sciences, 2021-07-30)
We applied a hybrid-dimensional flow model to pressure transients recorded during pumping experiments conducted at the Reiche Zeche underground research laboratory to study the opening behavior of fractures due to fluid ... -
Investment traps and resilience to shocks: An experimental study of Central Asian collective water governance
; ; (Irrigation and Drainage, 2022-03-16)
We theoretically and empirically investigate the investments of water users in a stylized local irrigation system. We model irrigation self‐management as an interdependent interaction of users in an evolutionary game and ... -
Ionospheric Corrections for Satellite Altimetry ‐ Impact on Global Mean Sea Level Trends
; (Earth and Space Science, 2022-04-25)
Atmospheric delay corrections for satellite altimetry measurements are essential for deriving highly accurate sea surface heights and reliable global mean sea level (GMSL) trend estimates. A commonly used method to correct ... -
Ionospheric Signatures of Secondary Waves From Quasi‐6‐Day Wave and Tide Interactions
; (Journal of Geophysical Research: Space Physics, 2021-03-31)
A sudden stratospheric waring occurred in the southern hemisphere during September 2019, accompanied by an exceptionally strong quasi‐6‐day wave (Q6DW). We examine the ionospheric response using global total electron content ... -

Iron Exports From Catchments Are Constrained by Redox Status and Topography
; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-01-18)
Fe(III) hydroxides stabilize organic carbon (OC) and P in soils. Observations of rising stream Fe concentrations are controversially posited to result from a flushing of iron‐rich deeper soil layers or a decrease of competing ... -
Iron isotope fractionation in soil and graminaceous crops after 100 years of liming in the long‐term agricultural experimental site at Berlin‐Dahlem, Germany
; ; Berns, Anne E.; Schweitzer, Kathlin; ; Bol, Roland; Amelung, Wulf (European Journal of Soil Science, 2020-03-04)
Sustainable arable cropping relies on repeated liming. Yet, the associated increase in soil pH can reduce the availability of iron (Fe) to plants. We hypothesized that repeated liming, but not pedogenic processes such as ... -
IRSL Signals from Maar Lake Sediments Stimulated at Various Temperatures
Schmidt, Esther Dorothe;; Sirocko, Frank; ; Frechen, Manfred (E&G – Quaternary Science Journal; Vol.60, No. 1)
Optisch stimulierte Lumineszenz (OSL) und infrarot stimulierte Lumineszenz (IRSL) wurden an sieben Feinkorn Proben von Kern JW3 aus dem Trockenmaar Jungfernweiher gemessen. Zwei verschiedene post-IR IRSL Messprotokolle ... -
Is Coulomb Stress the Best Choice for Aftershock Forecasting?
; ; ; (Journal of Geophysical Research: Solid Earth, 2020)
The Coulomb failure stress (CFS) criterion is the most commonly used method for predicting spatial distributions of aftershocks following large earthquakes. However, large uncertainties are always associated with the ... -
Is the soil moisture precipitation feedback enhanced by heterogeneity and dry soils? A comparative study
; ; ; (Hydrological Processes, 2021-09-09)
The interaction between the land surface and the atmosphere is a crucial driver of atmospheric processes. Soil moisture and precipitation are key components in this feedback. Both variables are intertwined in a cycle, that ... -
Is There a Semi‐Molten Layer at the Base of the Lunar Mantle?
; ; (Journal of Geophysical Research: Planets, 2023-06-29)
Abstract Parameterised by the Love number
k 2 and the tidal quality ... -

Isostatic Control of Axial Rivers and Large Drainage Basins on Passive Margins
; ; (Geophysical Research Letters, 2020)
More than half of the world's large rivers flow towards the ocean crossing passive continental margins. Here using an analytical solution and numerical models, we demonstrate that on passive margins, river basins may be ... -
Isotope and REE Characterization of Groundwater Aquifers within the Aquifer Storage and Recovery Programme in Sukhothai (N.-Thailand)
(Journal of Water Resource and Protection, 2016)Aquifer Storage and Recovery (ASR) was a pilot project for solving flood and drought problem in the northern part of Chao Phraya River basin, Thailand. This part of Thailand always faces flooding in rainy season and ... -
Isotope Dating of the Potash and Rock Salt Deposit at Bamnet Narong, NE-Thailand
Hansen, Bent T.;; Eckhardt, Monique; Putthapiban, Prinya; Assavapatchara, San (Open Journal of Geology, 2016)
Bamnet Narong is located in northeastern Thailand (Chaiyaphum Province). It is the largest salt mine in the country and has been mined for decades. The landscape in this part of Thailand is characterised by a low plateau, ... -
Isotope hydrology and water sources in a heavily urbanized stream
; ; ; (Hydrological Processes, 2021-10-06)
Complex networks of both natural and engineered flow paths control the hydrology of streams in major cities through spatio‐temporal variations in connection and disconnection of diverse water sources. We used spatially ... -
Isotope signatures and hydrochemistry as tools in assessing groundwater occurrence and dynamics in a coastal arid aquifer
(Environmental Earth Sciences, 2016)Groundwater from the La Paz arid coastal aquifer in Baja California, Mexico, is essentially the only source of drinking water for the local population and tourists, as well as irrigation water for agricultural needs. The ... -
Isotopen- und Elementuntersuchungen präsolarer Siliziumkarbid-Körner mit Flugzeit-Massenspektrometrie von Sekundärionen und Laser-ionisierten sekundären Neutralteilchen
(Univ. Münster (Westfalen), 2002)Präsolare Körner mit Größen von wenigen Mikrometern gestatten einen Einblick in das Sterninnere, da sie Kondensate von Sternmaterial sind und die Entstehung des Sonnensystems überlebten. Man extrahiert sie mit Säuren aus ... -
