Experiment and Simulation of Flood Increase along Lower Yellow River

Journal of Computers, 2012
In view of the abnormal phenomenon that a flood peak increased in August 2004 , July 2005 and August 2006 along the lower Yellow River, the experiments of this abnormal phenomenon is studied. It is found that the flood increase was due to the decrease the channel roughness in the propagation of high concentrated flood carrying the extra fine sediment ...

Assessment of the flow regime alterations in the Lower Yellow River, China

Ecological Informatics, 2012
Abstract Flow regimes have become a fundamental part of ecological informatics to reveal the complex interactional mechanism lying between flow regimes and ecological system. In this study, the changes of flow regimes were investigated to obtain the suitable flow regimes for maintaining the ecological integrity in the Lower Yellow River, China.
