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 ... -
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 ... -
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 ... -
Charakterisierung des hydromechanischen Verhaltens der Gesteine des Mittleren Buntsandsteins im Hinblick auf eine geothermische Nutzung: Strukturgeologische Geländeaufnahmen, gesteinsmechanische Untersuchungen und numerische Modellierungen
(2009-10-21)The objective of the current study was to evaluate the fluid flow in a geothermal fractured sandstone reservoir of the German Buntsandstein.The first part of the study comprises the analysis ... -
Conceptual Planning of Managed Aquifer Recharge in the Context of Integrated Water Resources Management for a semi-arid and a tropical Case Study in Palestine and Brazil: A new Integrated MAR Planning Approach.
(2018-08-07)This thesis focuses on the development, application and evaluation of new integrative approach for the planning of Managed Aquifer Recharge (MAR) concepts in the context of Integrated Water Resources Management (IWRM). The ... -
Fate of organic micropollutants in a karst aquifer system - Implications for sustainable raw water management
(2014-08-20)The fundamental understanding of karst aquifers is vital for the sustainable management of raw water quality and eventually the access to clean drinking water for up to one quarter of the world’s population. In order to ... -
Fault zones in potential geothermal reservoir rocks in the Upper Rhine Graben: Characteristics, permeability implications, and numerical stress field models
(2016-07-26)Fault zones in carbonate successions of the Middle Triassic Muschelkalk are potential target structures of hydrothermal projects in the Upper Rhine Graben (URG). A mixed-method approach was applied to make assumptions on ... -
Flow and transport in saturated and unsaturated fractured porous media: Development of particle-based modeling approaches
(2014-10-13)The main objective of this thesis is the development of particle-based flow and transport models to assist in the characterization of small-scale flow features and provide insight into the complex flow and transport dynamics ... -
Geomorphologische Untersuchungen mittels GIS- und Fernerkundungsverfahren unter Berücksichtigung hydrogeologischer Fragestellungen - Fallbeispiele aus Nordwest Syrien
(2008-02-12)The modern computer based geographic information system (GIS) offers a wide range of applications. The aim of this study is to generate a detailed GIS based geomorphological and geological description of different sub-regions ... -
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 ... -
Heat Transport Phenomena in Shallow Geothermal Boreholes
(2014-02-26)The branch of shallow geothermics is part of renewable energies with a potential that has not been fully exploited. Although various analytical and numerical approaches to determine the processes in vertical borehole ... -
Hydraulic Tomography: A New Approach Coupling Hydraulic Travel Time, Attenuation and Steady Shape Inversions for High-Spatial Resolution Aquifer Characterization
(2011-05-23)Hydraulic travel time, attenuation, and steady shape inversions are complementary methods for tomographic aquifer characterization. In this work, a coupled procedure is pre-sented that ... -
Hydrochemical and environmental isotope study of the geothermal water in Mae Chan (North) and Ranong (South) geothermal areas in Thailand
(2021-05-28)The exploration and development of geothermal resources in Thailand have been investigated for electricity generation since 1946. In total, 112 hot springs are manifested which mostly scattered at the granite body from the ... -
Hydrogeological characterisation of karst aquifers in semi-arid environments at the catchment scale – Example of the Western Lower Jordan Valley
(2014-09-26)The main objective of the study is the characterisation of karstified carbonate aquifers in the semi- arid climate zone, where groundwater resources are frequently threatened by overexploitation and pollution. Despite often ... -
Hydrological modelling in the meso scale semiarid region of Wadi Kafrein / Jordan -The use of innovative techniques under data scarcity
(2011-06-23)In order to effectively plan and manage the water resources of a country or geographical region, available water resources must be quantitatively assessed and hydrological processes must ... -
Identification and quantification of the effects of flow regime and matrix-conduit interaction in the characterization of karst aquifers
(2018-03-13)In addition to alluvial aquifers, karst aquifers are counted among the most important groundwater resources. Besides the high benefit of karstic springs, they also pose risks to the user or people living close to those ... -
Identification of indicator parameters for the quantitative assessment of vulnerability in karst aquifers
(2012-07-26)Prediction of contaminant transport in karst aquifers is therefore challenging and requires the knowledge of flow characteristics and transport processes in these systems. Based in this information, quantitative vulnerability ... -
