Abstract The Helvetic nappe system exhibits three-dimensional (3-D) features such as the lateral variation in geometry between the Morcles and Doldenhorn fold nappes or the Rawil depression. We perform 3-D finite element simulations of linear and power-law viscous flow to investigate fold nappe formation during shortening of a half graben with ...

Aeration efficiency with nappe flow over stepped cascades
Proceedings of the Institution of Civil Engineers - Water Management, 2007Hydraulic structures can increase dissolved oxygen levels by creating turbulent conditions where small air bubbles are carried into the bulk of the flow. Chute aeration is a particular instance of this. A chute is characterised by a steep bed slope associated with torrential flow. This chute flow may be either smooth or stepped.

Nappe flow in stepped channels – Occurrence and energy dissipation
2020The use of stepped spillways with nappe flow has been more closely related to the use of gabion spillways, where maximum flow velocities must be respected in order to guarantee the integrity of gabions. The increasing interest in stepped spillways built with different construction materials, either founded on the downstream slope of embankment dams ...

Stable isotope and 40 Ar/ 39 Ar measurements were made on samples associated with a major tectonic discontinuity in the Helvetic Alps, the basal thrust of the Diablerets nappe (external zone of the Alpine Belt) in order to determine both the importance of fluids in this thrust zone and the timing of thrusting.

Abstract Associated with the emplacement of the Lycian nappes, SW Turkey, Cretaceous limestones were thrusted over an ophiolitic melange in their front zone. Miocene flysch formed immediately in front of these nappes and were overthrusted by the Lycian nappes.

In a stepped-channel chute, the chute face is provided with a series of steps, from near the crest to the toe. Like many other high-speed flow configurations in hydraulic engineering, stepped-channel chute flows are characterized by the large amount of self-entrained air.

Volume of fluid approach for modeling nappe flow over hydraulic structures
Physics of FluidsAccurate simulation of the air–water interface of the overflowing sheet of water in weirs, referred to as nappe, is a challenging prospect from a computational fluid dynamics (CFD) modeling point of view. This study presents a systematic analysis of the widely used interface-capturing volume of fluid (VOF) technique for simulating nappe profiles, which
