Effect of a second layer on the time to failure of compressed riprap as mountain riverbank protection
Anton Schleiss, Michael Pfister, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi
Recently, Jafarnejad, Franca, Pfister, and Schleiss [2017. Time-based failure analysis of compressed riverbank riprap. Journal of Hydraulic Research, 55(2), 224–235. doi: 10.1080/00221686.2016.1212940] presented an experimental study on the stability of co ...
2019Sampling sufficiency for determining hydraulic habitat diversity
Anton Schleiss, Walter Gostner, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly, Christopher Robinson
The geometry and hydrodynamics of river reaches are key ecohydraulic descriptors. Statistics of water depth and velocity measurements are usually taken as proxies for habitat suitability in rivers. However, little is known about the sufficiency of data to ...
2019Potential erosion capacity of gravity currents created by changing initial conditions
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Jessica Zordan
We investigate to what extent the initial conditions (in terms of buoyancy and geometry) of saline gravity currents flowing over a horizontal bottom influence their runout and entrainment capacity. In particular, to what extent the effect of the introducti ...
2019Mass loss of density currents travelling over pourous bed
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
Polluted liquids leaking from their storages over the surrounding gravel beds or oil spilling into aquifers, are examples of gravity currents moving over a porous terrain. Density-driven flows provoked by saline or temperature differences or turbidity curr ...
2019Design of Riverbank Riprap Using Large, Individually Placed Blocks
Anton Schleiss, Michael Pfister, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi
The protection of river banks in mountain rivers by riprap requires large blocks with weights typically exceeding 1 t. Thus, the blocks have to be placed individually. Such packed riprap has a relatively small spacing between the blocks. Consequently, the ...
2019Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention
Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt, Stefano Tugulu, 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. ...
2018Depth-averaged momentum equation for gravity currents with varying density: coefficient in pressure term
Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
Gravity currents are often modelled by means of shallow water equations (SWEs). In these models, simplifications such as the consideration of a constant layer-averaged density are common. This note presents the complete and general derivation of a 2D depth ...
2018Probabilistic Prediction and Forecast of Daily Suspended Sediment Concentration on the Upper Yangtze River
Mário Jorge Rodrigues Pereira Da Franca, José Pedro Gamito de Saldanha Calado Matos
Sediment transport in suspension can represent more than 90% of a river's total annual flux of sediment. In the case of the Yangtze River, more than 99% of the sediment supplied to the sea is suspended load. Suspended sediment is thus an important componen ...
AMER GEOPHYSICAL UNION2018Transport of suspended sediments under the influence of bank macro-roughness
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez
River restoration works often include measures to promote morphological diversity and enhance habitat suitability. One of these measures is the creation of macro-roughness elements, such as lateral cavities and embayments, in the banks of channelized river ...
2018Influence of lateral embayments on suspended sediment transport under unsteady flow conditions
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Matthias Thalmann
Local widening in a channelized river is a common practice in restoration projects. The lateral embayments built for this purpose in the river banks are partially filled up by fine sediments. This allows the formation of aquatic habitats with hydraulic and ...
