Laboratory studies of partially saturated infiltration dynamics in analog fractured porous rock systems - under consideration of fracture-matrix interaction and network geometry
(2024-08-09)Fractured porous rocks are abundant groundwater reservoir formations often covered by a thick, unsaturated zone. The interplay between fractures and rock matrix can significantly impede infiltration, particularly when the ... -
Water level response to harmonic disturbances in confined aquifers: modeling, global sensitivity, and applications
(2024-06-13)In well-aquifer system, oscillatory water levels are often observed in monitoring wells when the aquifer is perturbed by harmonic disturbances, such as oscillatory pumping, ocean tide and seismic waves. In general, the ... -
Modelling the porosity loss in granular iron based permeable reactive barriers
(2022-11-24)The quality of groundwater resources globally has been under serious threat due to their exposure to a broad spectrum of anthropogenic pollutants. Permeable reactive barriers (PRBs) are an innovative technology being used ... -
Characterization of Hydraulic Properties in Fractured Aquifers Using Slug Test-based Hydraulic Tomography and Thermal Tracer Tomography
(2022-10-25)Fractured aquifers are widely distributed on the earth’s surface and are frequently encountered in many underground projects, such as groundwater resource evaluation, contaminants remediation, and geothermal energy ... -
Automated data processing and numerical methods for travel-time based hydraulic tomography
(2020-08-13)Travel time based hydraulic tomography is a useful and promising technique for reconstructing the spatial distribution of aquifer hydraulic properties (e.g., hydraulic diffusivity). Simultaneous Iterative Reconstruction ... -
Numerical modelling of single- and multi-phase flow and transport processes in porous media for assessing hydraulic fracturing impacts on groundwater resources
(2020-05-28)The environmental footprint of hydraulic fracturing has gained substantial attention in the water – energy nexus as the technology is relatively new and its long-term impacts are not thoroughly understood. Of primary ... -
Characterization of groundwater flow and vulnerability assessment of karstic aquifers - Development of a travel time based approach and application to the Tanour and Rasoun spring catchment (Ajloun, NW-Jordan)
(2016-08-24)Understanding the karst aquifer response to precipitation and contaminants transport, especially in arid to semi-arid areas, is a very important issue and a challenge due to the unique and heterogeneous characteristics of ... -
Backtracking approaches for the delineation of contamination sources
(2013-12-13)Contaminated groundwater poses a serious threat to drinking water resources all over the world. Even though contaminated water might be detected in observation wells, a proper clean-up is often only successful if the source ... -
Geostatistical three-dimensional modeling of the subsurface unconsolidated materials in the Göttingen area
(2013-09-25)Having a plenty of geotechnical records and measurements in Göttingen area, a subsurface three-dimensional model of the unconsolidated sediment classes was required. To avoid the repetition of the long expressions, from ... -
Decision Support for Managed Aquifer Recharge (MAR) Project Planning to Mitigate Water Scarcity based on Non-conventional Water Resources
(2011-09-16)The efficient integration into the water resources system and the implementation of Managed Aquifer Recharge (MAR) facilities requires careful planning if the overall water resources ... -
Flow Dynamics and Management Options in Stressed Carbonate Aquifer System, The Western Aquifer Basin, Palestine
(2011-06-29)Sustainable management of trans-boundary groundwater aquifers is usually difficult due to the complexity of natural and man-made systems. Therefore, sustainable management of trans-boundary ... -
Investigation of contaminant mass fluxes and reactive transport modelling of heterocyclic hydrocarbons at former gasworks sites
(2010-09-08)The presented thesis deals with the investigation of contaminant mass fluxes, offers an improved analysis of integral pumping tests and presents a reactive transport model based on those ... -
An integrated approach for the investigation of unconsolidated aquifers in a brackish environment - A case study on the Jordanian side of the lower Jordan Valley
(2008-09-18)In semi-arid areas groundwater systems are frequently not sufficiently characterized hydrogeologically and long term data records are generally not available. Long-term time series are necessary, however to design future ...
