Radionuclide Migration From an Underground Radioactive Waste Repository Under the Influence of Tectonic Fault Emergence: the Nizhnekanskiy Massif (Siberia, Russia) Example
A 3D numerical simulation of radionuclide migration from a potential repository of solid radioactive waste is carried out. The federal site is located in the Krasnoyarsk region (Siberia, Russia), at a distance...

Open AccessInfluence of tectonic perturbations on the migration of long-lived radionuclides from an underground repository of radioactive waste
We studied the influence of tectonic perturbations on the transport of potentially mobilized radionuclides in groundwater from a deep-mined repository of solid high-level radioactive waste. The study was carri...

Natural processes determining the hydrochemistry of groundwater in the Yarmouk basin
The Gorge of the Yarmouk River is the drainage base for groundwater flowing from different natural replenishment areas and aquifer lithologies. For the three riparian states (Syria, Jordan and Israel), the unc...

Assessing water consumption and aquifer discharge through springs based on the joint use of rain and flow data in the Yarmouk River Basin
The method is proposed for assessing water consumption in the transboundary basin under the scarce available data on exploitation of water resources. The method is based on analysis of the dynamic rain–flow re...

Numerical representation of rainfall field in basins of the Upper Jordan River and of the Yarmouk River
A non-linear complex rain–elevation regression model is proposed for the numerical representation of rainfall field in an area with complex plain/mountainous topography, non-uniform distribution of rain gauge ...

The effect of hydraulic anisotropies on intensely exploited groundwater resources: the numerical evaluation of a hydrothermal transboundary aquifer system in the Middle East
Previous investigations postulate the presence of a zone of high hydraulic anisotropy parallel to the principle axis of the Lower Yarmouk Gorge (LYG) in the Middle East. Driven by mixed convection, heated fres...

HT (Convection) Processes
In a geothermal system, unstable fluid density profiles due to temperature variations can trigger the onset and development of free thermal convective processes (J.W. Elder. Transient convection in a porous me...

Groundwater-driven temperature changes at thermal springs in response to recent glaciation: Bormio hydrothermal system, Central Italian Alps
Thermal springs are widespread in the European Alps, with hundreds of geothermal sites known and exploited. The thermal circulation and fluid outflows were examined in the area around Bormio (Central Italian A...

Assessing anthropogenic impacts on limited water resources under semi-arid conditions: three-dimensional transient regional modelling in Jordan
Both increasing aridity and population growth strongly stress freshwater resources in semi-arid areas such as Jordan. The country’s second largest governorate, Irbid, with over 1 million inhabitants, is alread...

Joint Research Project Brine: Carbon Dioxide Storage in Eastern Brandenburg: Implications for Synergetic Geothermal Heat Recovery and Conceptualization of an Early Warning System Against Freshwater Salinization
Brine was a scientific joint-project implemented to accompany a prospective CO2 storage site in Eastern Brandenburg, Germany. In this context, we investigated if pore pressure elevation in a CO2 storage reservoir...

Salinization problems in the NEGB: results from thermohaline simulations
The occurrence of salty waters close to the surface is a well-known problem in the North East German Basin. Previous numerical simulations showed that near-surface brine occurrences are due to the interaction ...

Fluid-dynamics driving saline water in the North East German Basin
In several areas of the North German Basin, saline water comes close to, or even reaches the surface. Available data from wells indicate that brine stratification is under unstable conditions in the deeper und...
