The collision of a gravitationally-driven horizontal current with barrier following release from confining lock is investigated using shallow water model the motion, together sophisticated boundary condition capturing local interaction. permits several overtopping modes: supercritical, subcritical, and blocked flow. analysed both mathematically numerically to reveal aspects unsteady motion comp...

The assessment of the dam failure consequences is fundamental to risk assessment, and linear weight sum method generally used. comprehensive evaluation involves many factors, dimensions each factor are inconsistent. key determine coefficient severity degree consequences. Based on traditional methods, a new model loss life, economic losses, environmental impact, social impact established after t...

The construction of a reservoir on large-thickness collapsible loess cover will significantly increase the occurrence dam break disasters. main reason may be that although gradation particle is not uniform. clay content less than 10%. Piping channels easily form under action force and collapsibility. Near-static liquefaction in body saturated condition lead to piping or loss soil strength. Ther...
