Riverbed is likely to be damaged in the natural conditions or due to human activities, which results in river morphology changed, and even the presence of extreme cases, such as crack or geological fault due to earthquake.

在离心轧辊生产时,个别轧辊工作层存在成分偏析。这表现为工作层表面碳化物聚集的亮斑缺陷,且工作层内部呈不规则层状分布。本文通过对问题轧辊的缺陷部位的硬度、化学成分和金相的检测,对亮斑产生的原因进行分析,确定了成分不均、孕育问题、铁水紊流和离心机振动是造成轧辊亮斑问题的主要原因。
DNA is the code of a life form, encoding its unique characteristics.Completely identical humans do not exist although their DNAs differences are only 0.1% to 0.4%.All fiver basins in the world have di

We consider incising mixed bedrock-alluvial rivers in uplifting mountain regions.We study both the equilibrium state of the river profile, at which uplift and incision are in balance, and the evolutio
The composite roughness of ice covered flows is a key parameter to determine the relationship between the flow and water stage.
River bed scour in cohesive soil at bridge contractions is a difficult problem to solve, in which many factors are included such as density, water contents, clay contents, mineral component and struct
Within the fluvial network, confluences are particular areas characterized by great ecological value where flow dynamics and bed morphology are much influenced by local patterns.
The process of self-formation of alluvial streams is considered in the light of the first and second laws of thermodynamics, and the Gibbs equation.The stream is treated as an isolated and irreversibl
The Lower Yellow River (LYR) has experienced a process of continuous channel degradation since the Xiaolangdi (XLD) Reservoir altered the flow and sediment regime entering the LYR.
The broad characterization and differentiation of river morphology in the source region of the Yangtze and Yellow Rivers is compared and analyzed.The source region of the Yangtze River contains genera
