Spatial transferability of landscape-based hydrological models

Landscape-based hydrological modelling: Understanding the influence of climate, topography, and vegetation on catchment hydrology

In this thesis, a novel landscape-based hydrological model is presented that was developed and tested in numerous catchments around the world with various landscapes and climate conditions. A landscape is considered to consist of a topography and an ecosystem living on it. Firstly, the influence of climate on hydrological process was studied. It...

Climate controls how ecosystems size the root zone storage capacity at catchment scale

Integrated glacier and snow hydrological modelling in the Urumqi No.1 glacier catchment

Deriving root zone storage capacity from Earth observation

Using expert knowledge to increase realism in environmental system models can dramatically reduce the need for calibration

Conceptual environmental system models, such as rainfall runoff models, generally rely on calibration for parameter identification. Increasing complexity of this type of models for better representation of hydrological process heterogeneity, typically makes parameter identification more difficult. Although various, potentially valuable,...

Climate controls how ecosystems size the root zone storage capacity at catchment scale

The root zone moisture storage capacity (SR) of terrestrial ecosystems is a buffer providing vegetation continuous access to water and a critical factor controlling land-atmospheric moisture exchange, hydrological response, and biogeochemical processes. However, it is impossible to observe directly at catchment scale. Here, using data from 300...

Metagenomic insights into the bio-functionality of 21 anaerobic biogas reactors (abstract)

Testing the realism of a topography-driven model (FLEX-Topo) in the nested catchments of the Upper Heihe, China

Although elevation data are globally available and used in many existing hydrological models, their information content is still underexploited. Topography is closely related to geology, soil, climate and land cover. As a result, it may reflect the dominant hydrological processes in a catchment. In this study, we evaluated this hypothesis...
