Entwicklung eines fernerkundungsgestützten Modellverbundes zur Simulation des urban-ruralen Landnutzungswandels in Nordrhein-Westfalen
(2011-07-12)
Die Veränderung der Landbedeckung und Landnutzung durch den Menschen nimmt im Zusammenhang mit der Diskussion über die Folgen des globalen Umweltwandels seit vielen Jahren eine zentrale Rolle ein. In weiten Teilen West- ...
Dynamical and Mechanistic Effects of High Pressure Fluids in the Earth's Crust
(2012-03-16)
Overpressurized fluids in the lithosphere play a significant role in a diverse range of globally observed natural hazards. Their occurrence during volcanic eruptions or earth degassing processes is apparent, but their ...
Einträge, Vorkommen, Verbreitung und gesundheitliche Bedeutung antibiotikaresistenter Bakterien in Abwasser und Gewässern: Ein sozial-ökologischer Beitrag zur Geographischen Gesundheitsforschung
(2011-11-29)
Antibiotika gelangen über natürliche Ausscheidung von Mensch und Tier sowie unsachgemäße Entsorgung in die Umwelt. Wichtige Eintragspfade stellen Abwasser, Klärschlamm und Gülle dar. Mikroorganismen können Resistenzen gegen ...
Experimental and numerical studies on solute transport in unsaturated heterogeneous porous media under evaporation conditions
(2012-08-31)
Groundwater level rise, root water uptake, or evaporation induces local upward water and solute fluxes in soils, causing soil salinization and rise of contaminants to the soil surface, and influencing the migration of ...
Disaster risk preparedness: the role of risk governance, multi-institutional arrangements and polycentric frameworks for a resilient tsunami early warning system in Indonesia
(2010-07-27)
This study examines, discusses and provides insights into tsunami risk resilience through an analysis of systems of governance, their architecture, and actor-agent perspectives, concentrating on the development of a Tsunami ...
Multiscale Modelling and Simulation of Rapid Granular Flows
(2013-11-19)
Granular flows are often encountered in geophysical contexts like debris flows, snow and rock avalanches, and also in transport processes in engineering applications. The damage caused by geophysical mass flows can be huge. ...
Cluster analysis of European surface ozone observations for evaluation of MACC reanalysis data
(2015-04-22)
The high density of European surface ozone monitoring sites offers good opportunities for investigation of the regional ozone representativeness and for evaluation of chemistry climate models. In this thesis we analyze ...
The Impact of Sensor Characteristics and Data Availability on Remote Sensing Based Change Detection
(2014-12-04)
Land cover and land use change are among the major drivers of global change. In a time of mounting challenges for sustainable living on our planet any research benefits from interdisciplinary collaborations to gain an ...
3D-Modeling of unsaturated flow dynamics and pattern: Potentials and Limitations at different spatial and temporal scales
(2016-06-14)
The aim of this thesis was to evaluate the suitability of the physically based, distributed 3D hydrological model HydroGeoSphere for the simulation of spatio-temporal soil moisture variability as well as unsaturated flow ...
On the probabilistic evaluation of decadal and paleoclimate model predictions
(2017-11-27)
The development of climate prediction systems for years to decades is an area of current research, as these time scales are important e.g. for the planning horizon of decision-makers. Those prediction systems can be improved ...
