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 ... -
Impact of climate and land use change on water resources, crop production and land degradation in a semi-arid area (using remote sensing, GIS and hydrological modeling)
(2015-05-05)Water resources have become scarcer in semi-arid regions of Iran due to increasing water use and recurrent drought. Any change to the hydrological cycle may have significant effects on the fragile ecosystems of Iran’s arid ... -
Impact of climate change on recharge and vadose-phreatic storage dynamics of a Mediterranean karst aquifer: Quantitative approach for the management of a complex groundwater resource
(2023-04-11)The Mediterranean basin will be severely affected by global warming and decreased average rainfall and is often portrayed as the most prominent climate change hotspot. At the same time, the Mediterranean basin is endowed ... -
Impacts of agricultural land acquisition for urbanization on smallholder agriculture and gender issues in affected communes: A case study in Huong Thuy town, Thua Thien Hue province, Vietnam
(2022-01-04)Abstract Agricultural Land Acquisition for Urbanization (ALAFU) is an inevitable process that has been happening around the world, especially in developing countries. It is the process by which the government acquires ... -
Impacts of rainforest transformation into oil-palm plantations on silicon pools in soils
(2023-03-30)Silicon (Si) is the second most abundant element in the Earth’s crust. In rocks, Si primarily occurs as primary silicates. In soils, Si is present mostly as secondary silicates or amorphous silica of biogenic or pedogenic ... -
Improved tracer techniques for georeservoir applications
(2015-01-26)For an efficient and sustainable use of georeservoirs, optimal reservoir management procedures are required. Such procedures often rely on tracer tests. Due to in-situ interactions between the tracer and the reservoir, ... -
Influence of oxygen fugacity on the viscosity of CO2-, H2O-, and halogen-bearing basaltic melts
(2019-03-04)Abstract The aim of this study is to demonstrate the effect of chlorine (Cl-), fluorine (F-), water (H2O) and carbon dioxide (CO2) on the viscosity of basaltic melts and a comparison to literature models. The basaltic ... -
Insights into the Holobiont of the Early Branching Metazoan Vaceletia sp. and its Biomineralization Strategy
(2017-12-05)Sponges are evolutionary and ecologically very successful animals. They are abundant and significant members of benthic communities throughout the world’s oceans. Having emerged during the Neoproterozoic era, sponges are ... -
Integrated approaches of social-ecological resilience assessment and urban resilience management
(2016-02-10)The urban system is a multi-interaction system, due to the rapid urbanization and intertwined vulnerability of the ecological system. It will be a challenge to maintain a sustainable development of the urban and urbanizing ... -
Investigating the dielectric profiling of ice cores
(2021-02-12)The polar regions are important components of the Earth's climate system, as these areas are the main sources of fresh water on Earth. Any conflicts in that system can affect people's lives in different ways. Numerous ... -
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 ... -
Investigations on groundwater dewatering by using vertical circulation wells: Numerical simulation method development and field validation
(2015-03-06)Construction dewatering is a common engineering problem encountered at construction and mining sites. Successful site dewatering requires proper design and implementation of groundwater lowering techniques depending on ... -
Inwertsetzung regionaler traditioneller Produkte am Beispiel des neuen EU-Mitgliedsstaats Malta
(2005-12-06)The PhD thesis, taking Maltese products from the foodstuff and handicraft sector as example, shows how regional traditional products can be set in value for touristic marketing but also for ... -
Isotope- and REE-Characterization of Groundwater Aquifers
(2016-06-15)This PhD thesis investigates the application of isotope techniques in groundwater aquifers, with the main focus on systematic variations of the Strontium (Sr) isotopes and chemical composition including fractionation ... -
Isotopengeochemische Untersuchungen an postglazialen Karbonaten des Neoproterozoikums aus China und Namibia
(2017-12-22)The Neoproterozoic time, especially the Cryogenian is characterised by extreme climate conditions. Two of the known global glaciations – the Sturt and Marinoan – occurred during this period. In the following Ediacaran ... -
K-Ar-Datierungen an detritischen Muskoviten und Sm-Nd-Modellalter prä- und synorogener schwach metamorpher Sedimente im Rhenoherzynikum - Grundlegende Daten zur Quantifizierung orogener Prozesse am Beispiel der Varisziden
(2001-07-06)The combination of K-Ar cooling ages of detrital muscovites, Sm-Nd model ages and geochemical investigations allows the discrimination of four crustal segments as provenance areas for the ... -
“Keratose” sponge fossils and microbialites: a geobiological contribution to the understanding of metazoan origin
(2015-02-18)Molecular clock and the fossil record at the Precambrian-Cambrian boundary indicate that animals probably had a long evolutionary history in the Precambrian which is still poorly explored and understood. This PhD study was ... -
Kommunalismus und Raumproduktion am Beispiel der indischen Metropole Hyderabad
(2023-01-11)Hyderabad is a fast growing emerging Indian Megacity. Along with globalisation rapid and drastic changes have taken place resulting in spatial fragmentations and new conflicts. The Muslim-dominated old city of Hyderabad ... -
