Hurricane Matthew in 2100: effects of extreme sea level rise scenarios on a highly valued coastal area (Palm Beach, FL, USA)
; ; ; (Geo-Marine Letters, 2021-09-08)
Sea-level rise represents a severe hazard for populations living within low-elevation coastal zones and is already largely affecting coastal communities worldwide. As sea level continues to rise following unabated greenhouse ... -
Hydrated sub-arc mantle: a source for the Kluchevskoy volcano, Kamchatka/Russia
Dorendorf, Frank; Wiechert, Uwe; (Earth and Planetary Science Letters, 2000)
Oxygen isotope ratios of olivine and clinopyroxene phenocrysts from the Kluchevskoy volcano in Kamchatka have been studied by CO2 and ArF laser techniques. Measured δ18O values of 5.8–7.1‰ for olivine and 6.2–7.5‰ for ... -

Hydraulische Eigenschaften unterschiedlicher Sphagnum-Torfe
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 46; 2016)Abstract: On an experimental site in Lower Saxony samples of various Sphagnum peats were collected for laboratory analyses of hydraulic properties. It turned out that the hydraulic properties of the peats are different ... -
Hydro Explorer: An interactive web app to investigate changes in runoff timing and runoff seasonality all over the world
; Vormoor, Klaus; Francke, Till; (River Research and Applications, 2021-01-26)
Climatic changes and anthropogenic modifications of the river basin or river network have the potential to fundamentally alter river runoff. In the framework of this study, we aim to analyze and present historic changes ... -
Hydrochemical evaluation of water resources and human impacts on an urban karst system, Jordan
; ; ; ; (Hydrogeology Journal, 2020-06-05)
Urban karst aquifers are threatened by anthropogenic activities, especially in semiarid developing countries. Recent water-sampling campaigns assessed the extent of groundwater-quality impairment in the Wadi Shueib in ... -
Hydrochemistry and environmental isotopes (18O, 2H, 3H, 3He/4He) of groundwater and floodwater in the great area of Hurghada, Eastern Desert of Egypt
(Environmental Earth Sciences, 2021-05-28)Porous and fractured aquifers exist in the area of Hurghada, Eastern Desert of Egypt, whose recharge processes through the common flash floods are not identified. Hydrochemical parameters, stable isotopes 18O, ... -
Hydroclimate in the Pamirs Was Driven by Changes in Precipitation-Evaporation Seasonality Since the Last Glacial Period
; Makhmudov, Zafar; Rajabov, Ilhomjon; ; ; ; ; ; ; ; (Geophysical Research Letters, 2019)
The Central Asian Pamir Mountains (Pamirs) are a high-altitude region sensitive to climatic change, with only few paleoclimatic records available. To examine the glacial-interglacial hydrological changes in the region, we ... -

Hydrogen Diffusion in Clinopyroxene at Low Temperatures (195°C–400°C) and Consequences for Subsurface Processes
; ; ; (Geochemistry, Geophysics, Geosystems, 2022-12-12)
Studying diffusion of hydrogen in nominally anhydrous minerals, like clinopyroxene, at low temperatures is a challenging task due to experimental and analytical difficulties. In this study, to overcome these problems we ... -
Hydrogen incorporation in enstatite in the system MgO-SiO2-H2O-NaCl
(Contributions to mineralogy and petrologyContributions to mineralogy and petrology, 2008)The incorporation of hydrogen in enstatite in a hydrous system containing various amounts of NaCl was investigated at 25 kbar. The hydrogen content in enstatite shows a clear negative correlation to the NaCl-concentration ... -
Hydrogen-deficient central stars of planetary nebulae
(Univ. Potsdam, 2009)Central stars of planetary nebulae are low-mass stars on the brink of their final evolution towards white dwarfs. Because of their surface temperature of above 25,000 K their UV radiation ionizes the surrounding material, ... -
