Modelling impacts of climate change on water resources in the Volta Basin, West Africa
(2010-01-27)
The Volta River Basin is one of the largest river systems in Africa covering an area of approximately 400,000 km2 and shared by six riparian states of West Africa. The semi-arid to sub-humid regions of the basin ...
Analyse schneehydrologischer Prozesse und Schneekartierung im Einzugsgebiet des Oued M’Goun, Zentraler Hoher Atlas (Marokko)
(2007)
Die in der vorliegenden Arbeit gewählten Methoden zur Analyse der schneehydrologischen Prozesse und zur Schneekartierung im Einzugsgebiet des Oued M’Goun lieferten eine Fülle von Daten und Informationen über die Facetten ...
Soil degradation by water erosion in a sub-humid West-African catchment: a modelling approach considering land use and climate change in Benin
(2008)
Soil degradation threatens agricultural production and food security in Sub-Saharan Africa. In the coming decades, soil degradation, in particular soil erosion, will become worse through the expansion of agriculture into ...
Untersuchungen zum Bodenwasserhaushalt und Modellierung der Bodenwasserflüsse entlang eines Höhen- und Ariditätsgradienten (SE Marokko)
(2005)
Übergeordnete Zielvorstellung der vorliegenden Arbeit ist es, die wichtigsten Steuergrößen des Bodenwasserhaushalts in einem Trockenraum zu erfassen und zu analysieren. Die Studie ist in das IMPETUS-Projekt eingebunden und ...
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 ...
Modeling climate and land use change impacts on water resources and soil erosion in the Dano catchment (Burkina Faso, West Africa)
(2018-07-11)
The study assesses the effect of climate and land use change on water resources and soil ero-sion in the Dano catchment, Burkina Faso. Field measurements and derived process under-standing are complemented by a physically ...
Evaluating the Contribution of Remote Sensing Data Products for Regional Simulations of Hydrological Processes in West Africa using a Multi-Model Ensemble
(2019-05-02)
Water is a crucial resource for human health, agricultural production and economic development. This holds especially true in West Africa, where large parts of the population work as self-sustaining farmers. Accurate ......
Integrated Terrestrial Simulations over Europe: Groundwater-Atmosphere Feedbacks with Altered Water Tables Including the Effect of Recent Droughts
(2023-08-08)
The groundwater flow is an essential part of the terrestrial system encompassing the atmosphere, land surface, and subsurface. In past research, there was usually no focus on water in the subsurface because climate models ...
