Improving the spatial representation of basin hydrology and flow processes...

This dissertation aims at improving the spatial representation of basin hydrology and flow processes in the SWAT model.
Dissertation

Ecohydrologic and hydraulic stream modelling to describe aquatic habitats

Naturnahe Einzugsgebiete, Fließgewässer und die aquatische Vielfalt wurden primär aufgrund der Auswirkungen der industriellen und urbanen Entwicklung sowie der Intensivierung der Landwirtschaft weltweit degeneriert. Diese Veränderungen haben auf verschiedenen Skalen stattgefunden und daher sind Rehabilitationsmaßnahmen...
Dissertation

A guideline for hydrologically consistent models

Hydrological models are established tools to simulate discharge and hydrological processes of watersheds. Scenario simulations and resource management studies are carried out, assuming that hydrological processes are simulated appropriately. However, several studies revealed that satisfying discharge...
Dissertation

Development and testing of a phytoplankton index of biotic integrity (P-IBI)...

This dissertation developed and tested a phytoplankton index of biotic integrity (P-IBI) to assess the ecological conditions of German lowland rivers, and simulated the daily phytoplankton biomass (as indicated by chlorophyll a) dynamics for the purpose of water quality forecasting and watershed management....
Dissertation

Assessing the impact of land use change on hydrology and sediment yield...

This dissertation describes the application of the eco-hydrological model SWAT to a watershed in the Three Gorges Region, which is located in Hubei Province and Chongqing Municipality in Central China. The region is heavily influenced by the construction of the Three Gorges Dam on Yangtze River, which...
Dissertation

Valuation of Mangrove Ecosystems along the Coast of the Mekong Delta in...

Mangrove ecosystem is among the most productive and valuable eosystems in the world.The services provided by mangrove ecosystems to human well-being are well acknowledged in literature. Mangrove forests provide not only direct use values such as timber materials and fisheries resources but also indirect...
Dissertation

Development and application of a non-point sources pollution model for...

This dissertation describes the hydrology and non-point source pollution of the humid, subtropical Xitiaoxi catchment in the south-eastern China and comprises a hydrologic and nutrient dynamics simulation there. The study presents at first an interpretation of hydrological processes influenced by anthropological...
Dissertation

Water quality assessment and management of lowland river catchment

This dissertation describes at first the hydrology and the long-term impact of point and diffuse source pollution on nutrient loads based on the current agricultural practices and sewage disposals in rural lowland catchments. The evaluations of Best Management Practices (BMPs) for water quality improvement...
Dissertation

Assessing water colour of lakes with high and medium spatial resolution...

Remote sensing techniques can assist traditional lake monitoring approaches by supplying spatial information on optically active lake ecology indicators, i.e. chlorophyll-a (CHL), total suspended matter (TSM), coloured dissolved organic matter (CDOM), and, especially in optically shallow waters, water...
Dissertation

Assessment of forest cover dynamics in Paraguay A case study of the Upper...

The Upper Parana Atlantic Forest (BAAPA) in Paraguay is one of the most threatened tropical forests in the world. The rapid growth of deforestation has resulted in the loss of 91% of its original cover. Numerous efforts have been made to halt deforestation activities, however farmers’ perception towards...
