Modeling hydrological processes in a semi-arid mountainous catchment at the regional scale
(2013-04-02)
In the Upper Drâa Valley (14,988 km2) on the southern slopes of the Moroccan High Atlas Mountains, a highly variable precipitation and large evaporation losses cause major water availability problems. The combined ...
Statistical Quality Assurance and Peer Review in Primary Data Publication
(2013-01-23)
Publication of results is an elementary part of scientific work. Started in in 17th century with the traditional scientific publications several new forms emerged in recent years, triggered by the digital ...
Modeling the spatio-temporal evolution of fracture networks and fluid-rock interactions in GPU: Applications to lithospheric geodynamics
(2013-04-16)
In this thesis, I present the theory and modeling of poro-elasto-plastic rheology coupled to a non-linear diffusion equation with a step increase in permeability at the onset of slip. This theoretical model is implemented ...
Atmospheric Downscaling using Multi-Objective Genetic Programming
(2017-10-10)
Numerical models are used to simulate and to understand the interplay of physical processes in the atmosphere, and to generate weather predictions and climate projections. However, due to the high computational cost of ...
Generating high resolution precipitation conditional on rainfall observations and satellite data
(2017-09-15)
This study is part of the high resolution reanalysis project proposed for Germany and Europe (Bollmeyer et. al., 2014) within the framework of the Hans Ertel Centre for Weather Research (HErZ). The reanalysis for Germany ...
Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
(2017-04-20)
Northwestern Turkey and the southern Levant are key regions for studying vegetation and climate developments during migration phases of modern humans and the origin and expansion of agriculture. Both regions have a long ...
Palaeoclimate Reconstruction in the Levant and on the Balkans
(2017-08-25)
For an understanding of the climate system’s variability, knowledge of the past climate is essential. Continuous observations are not available for longer than the last 100 years, a period that is insufficient to understand ...
Biogeomorphic dynamics in the Turtmann glacier forefield, Switzerland
(2017-05-19)
Worldwide, glacier retreat enlarges glacier foreland areas, which are characterized by pronounced geomorphic and ecologic dynamics. Feedbacks between these dynamics are believed to drive glacier foreland landscape development, ...
Multiseasonal Remote Sensing of Vegetation with One-Class Classification – Possibilities and Limitations in Detecting Habitats of Nature Conservation Value
(2017-07-03)
Mapping of habitats relevant for nature conservation often involves the identification of patches of target habitats in a complex mosaic of vegetation types extraneous for conservation planning. In field surveys, this is ...
Improvements and application of the STatistical Analogue Resampling Scheme STARS
(2017-07-03)
Basically, there are two approaches to downscale climate simulations from global climate models to a regional scale: dynamical and statistical downscaling. This thesis focuses on a statistical method – the Statistical ...
