Along-strike shear-sense reversal in the Vals-Scaradra Shear Zone at the front of the Adula Nappe (Central Alps, Switzerland)

, 2017
The Adula Nappe in the Central Alps comprises pre-Mesozoic basement and minor Mesozoic sediments, overprinted by Paleogene eclogite-facies metamorphism. Peak pressures increase southward from ca.

Oxygen transfer variation along steps of a prototype-scale stepped spillway in nappe flow regime

Based on long-term data, oxygen levels have decreased in temperate natural lakes because of thermal stratification and eutrophication. Similar conditions can be observed in newly filled reservoirs, with consequences on the environment. Air-water flows taking place on hydraulic structures are helpful to increase the dissolved oxygen concentration ...

Modelling Turbulent Kinetic Energy and Streamlines Over Gabion Stepped Weirs

Civil and Environmental Engineering
Gabion weirs are environmentally friendly hydraulic structures that regulate floods and reduce bottom erosion by controlling flow velocity. This study aims to simulate the flow over gabion stepped weirs numerically.

Nappe flows on a prototype-scale stepped chute: observations of flow patterns, air-water flow properties, energy dissipation and dissolved oxygen

, 2019
Air-water flows occur commonly in stepped spillways including the nappe flow regime for low flow rates. The present laboratory experiments researched the nappe flow regime in a stepped chute with prototype-scale steps height providing unique insights into the evolution of nappe flows along a stepped chute.

Affect Factors Analysis of Aerated Cavity of X-shaped Flaring Gate Pier

工程科学与技术, 2007
:A step spillway placed behind X-shaped flaring gate pier was proposed and applied in practical engineering. If the first step is higher than the others, cavity will exist between the nappe and the step spillway.The flow with air entrainment will occur ...
