It is shown that land-use changes as well as the water-level fluctuations of the reservoir are the crucial drivers for the soil erosion and landslide hazard. The paper describes the workflow of the project and introduces case studies, representing the current state of our research. thus, rapidly changing conditions in landscapes and their At the same time, the.
In this context, our research objectives are (1) to better understand the mechanisms of soil erosion, landslides, and diffuse matter fluxes in the TGR and their anthropogenic and environmental control factors, (2) to predict their hazard potential by combining spatial and temporal, scenario-driven high-resolution modeling in combination with multi-scale earth observation data, and (3) to develop a multi-component approach for the assessment and monitoring of geogene structures and processes. Hence, the water-level uctuations and the Hence, this collaborative study can contribute to the land-use change are concluded to act as the key drivers for understanding of large-scale anthropogenic impacts and the geo-hazards examined in this research framework. Knowing the extent and consequences of those geo-hazards for the landscape is essential to predict and evaluate their risk potential and allows for the development of strategies for a sustainable future land use in the Three Gorges Region (TGR). Soil erosion and landslides are major geo-hazards. Due to considerable resettlements, large-scale expansion of infrastructure and shifts in land use and management, the TGD project has irreversible impacts on the Upper Yangtze River Basin and strongly challenges the environmental conditions of this fast-developing region.
One prominent example is the Three Gorges Dam (TGD) at the Yangtze River in China. Large dam projects attract worldwide scientific attention due to their environmental impacts and socioeconomic consequences.
