Catchment drainage network scaling laws found experimentally in overland flow morphologies

David Andrew Barry, Paolo Perona, Andrea Rinaldo, Mohsen Cheraghi

The scaling relation between the drainage area and stream length (Hack’s law), along with exceedance probabilities of drainage area, discharge and upstream flow network length are well known for channelized fluvial regions. We report here on a laboratory e ...

The origin of fine sediment determines the observations of suspended sediment fluxes under unsteady flow conditions

Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez

Field observations in a wide range of environments have shown that sediment availability is a major control on the suspended sediment observations in streams. Here we examine, via laboratory experiments, how the amount of proximal in-channel fine sediment ...

Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention

Mário Jorge Rodrigues Pereira Da Franca, Stefano Tugulu, Sebastian Schwindt, Alessandro Reffo

Sediment traps with partially open check dams are crucial elements for flood protection in alpine regions. The trapping of sediment is necessary when intense sediment transport occurs during floods that may endanger urban areas at downstream river reaches. ...

Fabrication method of functional micro/nano structures over large-area, flexible and high curvature surfaces, by drawing a fiber from a preform

Dang Tùng Nguyen, Fabien Sorin, Alexis Gérald Page, Wei Yan, Yunpeng Qu

The method for drawing a fiber with a textured surface comprises the following steps: - forming of a preform from which the fiber is to be drawn with a textured surface; - addition of an outer layer to the textured preform to preserve the shape of the text ...
