报告人简介:

Professor Huib de Vriend is a civil engineer   by training. He received his PhD from Delft University of Technology. Before   his retirement in 2012 he was director science of Deltares and part-time   professor of River Engineering and Eco-hydraulics at Delft University of   Technology.

Until July 2013 Prof. de Vriend was director   of the EcoShape Foundation, which co-ordinates the ‘Building with Nature’   innovation programme executed by a consortium of government agencies,   universities, research organisations, consultants and engineering   contractors. He has over 200 scientific publications in the fields of rivers,   estuarine, coastal and seabed dynamics. Prof. de Vriend is a member of the   National Commission for the EIA, and member of the thinktank on flood safety   of the Netherlands Ministry of Infrastructure and Environment. As a private   consultant he presently advises various large infrastructural projects in the   Netherlands.


报告内容:

Making use of some basic morphological theory, we compare the responses to a variety of interventions and environmental changes for the river Rhine and Meuse in the Netherlands and the middle and lower reaches of the Yangtze in China. This makes clear that such interventions and changes give rise to different morphological processes at different temporal and spatial scales. Effects often turn out to extend upstream (‘climbing’ or ‘descending’ river), as well as downstream (‘rising’ or ‘sinking’) river. The equilibrium slope turns out to provide a good handle to explain many of these effects.  Subsequently, the impact on the sediment supply to the estuary is considered for various interventions. All this leads to the conclusion that these rivers have things in common, suggesting that Rhine and Meuse can be considered as small-scale ‘field labs’ for the Yangtze, but that there are alse differences, suitable to drive further learning.
