Using continuous electrical conductivity measurements to derive major solute concentrations in karst systems
Hydrochemical data of karst springs provide valuable insights into the internal hydrodynamical functioning of karst systems and support model structure identification. However, the collection of high-frequency time series of major solute species is limited ...
WILEY2023Deriving Major Ion Concentrations at High Resolution from Continuous Electrical Conductivity Measurements in Karst Systems
Time series of hydrochemical parameters support the investigation of dominant karst hydrological processes and conceptual model structures. Nevertheless, high costs for sample collection and analyses cause hydrochemical data to be rarely available at a suf ...
SPRINGER INTERNATIONAL PUBLISHING AG2023Calibration of a lumped karst system model and application to the Qachqouch karst spring (Lebanon) under climate change conditions
Flow in complex karst aquifers is challenging to conceptualize and model, especially in poorly investigated areas, in semiarid climates, and under changing climatic conditions; however, it is necessary in order to implement long-term sustainable water mana ...
2020Mass loss of density currents travelling over pourous bed
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
Polluted liquids leaking from their storages over the surrounding gravel beds or oil spilling into aquifers, are examples of gravity currents moving over a porous terrain. Density-driven flows provoked by saline or temperature differences or turbidity curr ...
2019Matching ecohydrological processes and scales of banded vegetation patterns in semiarid catchments
Gabriele Manoli, Gabriel George Katul, Peter Molnar
While the claim that water-carbon interactions result in spatially coherent vegetation patterning is rarely disputed in many arid and semiarid regions, the significance of the detailed water pathways and other high frequency variability remain an open ques ...
2016Evaluation of geochemical and hydrogeological processes by geochemical modeling in an area affected by evaporite karstification
The Ebro Valley in the outskirts of Zaragoza (NE Spain) is severely affected by evaporite karstification, leading to multiple problems related to subsidence and sinkhole formation. In this work, a combination of inverse (mixing + mass-balance) and forward ...
Elsevier Science Bv2015Limestone reaction in calcium aluminate cement–calcium sulfate systems
Karen Scrivener, Julien Bizzozero
This paper reports a study of ternary blends composed of calcium aluminate cement, calcium sulfate hemihydrate and limestone. Compressive strength tests and hydration kinetics were studied as a function of limestone and calcium sulfate content. The phase e ...
Elsevier2015Giant lacustrine pockmarks with subaqueous groundwater discharge and subsurface sediment mobilization
Subsurface fluid flow in oceans and lakes affects bathymetric morphology, sediment distribution, and water composition. We present newly discovered giant lacustrine pockmarks in Lake Neuchatel (up to 160m diameter and 30m deep) that rank among the largest ...
American Geophysical Union2015Hydromechanical coupling in CO2 geological injection processes
CO2 storage in deep aquifers is considered as a potential technology to reduce the greenhouse effects of CO2. Practically, a large-volume (>1 Mt/year) of CO2 could be injected into a system that consists of a highly porous host aquifer covered by a low-per ...
2014Poroelastic behavior of Calcarenite for the purposes of geologic CO2 storage
Lyesse Laloui, Roman Makhnenko
Geologic CO2 sequestration is considered to be the most promising technique to reduce the concentration of greenhouse gases in the atmosphere. Among all the storage options, deep saline aquifers have the greatest potential and due to their worldwide occurr ...
