Flow during the evening transition over steep Alpine slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau

A field campaign, the Slope Experiment near La Fouly (SELF-2010), was conducted to monitor the evening transition of slope flows on clear-sky days from July to September 2010 in a narrow valley of the Swiss Alps. A steep west-facing slope with inclinations ...

Bend scour reduction induced by an air-bubble screen under live-bed conditions

Anton Schleiss, Koen Blanckaert, Violaine Dugué

Open-channel bends are characterized by complex interactions between streamwise flow, curvature-induced secondary flow and bed morphology. These bend effects cause erosion near the outer bank, and deposition near the inner bank. Previous laboratory experim ...

Early Anthropogenic Transformation of the Danube-Black Sea System

Jed Oliver Kaplan

Over the last century humans have altered the export of fluvial materials leading to significant changes in morphology, chemistry, and biology of the coastal ocean. Here we present sedimentary, paleoenvironmental and paleogenetic evidence to show that the ...

Flow patterns induced by a bubble screen in a sharply curved flume based on Acoustic Doppler Velocity Profiler measurements

Anton Schleiss, Koen Blanckaert, Violaine Dugué

Open-channel bends are characterized by a bed morphology where erosion occurs near the outer bank and a point bar develops at the inner bend. This morphology is induced by complex interactions between the streamwise flow, the curvature-induced secondary fl ...

Flow processes near smooth and rough (concave) outer banks in curved open channels

Anton Schleiss, Koen Blanckaert, Alexandre José Pessanha De Oliveira Caimoto Duarte

Flow processes near the (concave) outer bank in curved river reaches are investigated in a laboratory flume, with focus on the influence of the bank roughness. An outer-bank cell of reversed secondary flow occurs for all the investigated roughness configur ...

Quasi-3D modelling of bed shear stresses at high curvature

Koen Blanckaert

Single thread meandering rivers exhibit complex planformpatterns in their floodplains, resulting from a complex interaction between flow, bed and bank morphology. The flow through meander bends may be characterized by primary flow in streamwise direction a ...

An air-bubble screen used as a countermeasure to reduce erosion in open-channel bends

Anton Schleiss, Koen Blanckaert, Violaine Dugué

In open-channel bends, interactions between streamwise flow, curvature-induced secondary flow and sediment transport lead to a typical bar-pool bed topography. Erosion occurs near the outer bank that can endanger structures, whereas deposition occurs near ...

Flow and sediment dynamics in channel confluences

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, André Roy

Confluences with relatively low discharge and momentum flux ratios where a small steep tributary with a high supply of poorly sorted sediment joins a large, low-gradient main channel commonly occur in nature, but they have not yet been investigated. Measur ...

Coupled dynamics of the co-evolution of gravel bed topography, flow turbulence and sediment transport in an experimental channel

Fernando Porté Agel

A series of flume experiments were conducted in a large experimental channel at the St. Anthony Falls Laboratory to understand the coupled dynamics of flow and bed forms above the sediment-water interface. Simultaneous high resolution measurements of veloc ...

Riprap Protection of Vertical-Wall and Spill-Through Bridge Abutments

Anton Schleiss, António Heleno Cardoso

Scour around bridge abutments frequently leads to the collapse of bridge superstructures. Consequently, scour countermeasures are usually designed and installed by river engineers, riprap matting being the most widespread solution. The associated design cr ...
