With the advantages of simple structure, good energy dissipation effect and so on, sky jump is widely used in water conservancy project. But at present, prediction about range free nappe not complete. The studies show that ejection angle different locations outlet section, but specific distribution section velocity still unclear. measurement mostly direct measurement, how to accurately control ...

Rubber dams have been used for the past 40 years in river and coastal engineering applications, in Australia and overseas. Despite the increasing interest for rubber dams, little information is available on their hydraulic performances. The overflow characteristics of inflated rubber dams are re-investigated. New analytical calculations provide information on the wall pressure distribution and ...

Megathrust earthquakes cause tsunamis that can destroy coastal structures and damage buildings, resulting in injuries deaths. To prevent these consequences reduce the risk of failure structures, it is essential to understand exact mechanism structure failure. Sub-nappe air cavity pressure during overflow a vertical structure, which main topic this research, increase but had not yet been quantif...

Abstract The petrochronological records of eclogites in the Scandinavian Caledonides are investigated using EPMA and LA-ICPMS zircon apatite for U–Pb geochronology, combined with major trace element characteristics. Metamorphic from two Lofoten-Vesterålen Complex (Lofoten Archipelago region) collectively yielded a Concordia age 427.8 ± 5.7 Ma an upper intercept 425 30 Ma. Apatites same provided...
