Bewertungsrobustheit der Gewässerstrukturkartierung nach dem Deutschen Vor-Ort-Verfahren
(2016-08-09)
Das Deutsche Vor-Ort-Verfahren der Bund- und Länderarbeitsgemeinschaft Wasser (LAWA-VO-Verfahren) liefert Gewässerstrukturdaten als Grundlage für zahlreiche wasserwirtschaftliche Anwendungen wie Wasserkörperbewertung, ...
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 ...
Multiple and more frequent natural hazards: The vulnerability implications for rural West African communities
(2016-12-22)
Rural, subsistence agriculture dependent communities in the West-Sudanian Savannah climate zone are dependent on a single rainy season to produce the crops that they need to sustain themselves for the following year. ...
Interlinkages of Land Degradation, Marginality and Land Use Cover Change in Kenya: Development of an interdisciplinary framework using remote sensing and GIS
(2015-12-01)
Land degradation (LD) is a global problem affecting and being affected by socio-ecological systems. In this thesis the interlinkages of LD, marginality and land use cover change (LUCC) in Kenya based on remote sensing and ...
The role of soil heterogeneity on field scale evapotranspiration: 3D integrative modelling and upscaling of root water uptake
(2015-09-24)
Background and Motivation: Hydrological models mainly rely on empirical functions to describe root water uptake. However, in case of water limitation due to either scarce or heterogeneously distributed soil water, plants ......
Potenziale quantitativer Landschaftsanalysen als Monitoring-Instrument im Gebietsnaturschutz: Untersuchungen am Beispiel des Biosphärenreservats Rhön
(2017-08-25)
Im Kontext des Monitorings im Gebietsnaturschutz treten bei der Quantifizierung von Land-schaftsveränderungen auf Basis kategorialer Daten unterschiedliche methodische und inhalt-liche Probleme auf, die in der Arbeit am ...
Entwicklung eines automatisierten Wolkendetektions- und Wolkenklassifizierungsverfahrens mit Hilfe von Support Vector Machines angewendet auf METEOSAT-SEVIRI-Daten für den Raum Deutschland
(2013-03-20)
Wolken stellen im Klimasystem der Erde einen zentralen Faktor dar, nicht nur in Bezug auf die Niederschlagsverteilung, sondern auch in Verbindung mit Effekten auf Strahlungsvorgänge innerhalb der Atmosphäre. Eine genaue ...
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 ...
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, ...
Modelling the hydrological impact of rice intensification in inland valleys in Benin (West Africa)
(2018-01-25)
The aim of this study is to assess the impact of climate change and rice intensification on water availability, water quality, and rice production. A spatial explicit approach was developed to determine suitable areas for ...
