Stochastic Simulations and Machine Learning Modeling to Predict Bedload Transport and Bed Topography
In computational hydraulics models, predicting bed topography and bedload transport with sufficient accuracy remains a significant challenge. An accurate assessment of a river's sediment transport rate necessitates a prior understanding of its bed topograp ...
EPFL2024Parametric transitions between bare and vegetated states in water-driven patterns
Conditions for vegetation spreading and pattern formation are mathematically framed through an analysis encompassing three fundamental processes: flow stochasticity, vegetation dynamics, and sediment transport. Flow unsteadiness is included through Poisson ...
2018Temporal variability in thermally-driven cross-shore exchange: the role of semidiurnal tides
We examine temporal variability of thermally-driven baroclinic cross-shore exchange in the context of a tropical fringing reef system focusing on the role of tidally driven alongshore flow. Ensemble diurnal phase averaging of crossshore flow at the Kilo Na ...
2018Spatial and temporal turbidity currents sediment deposition assessment
Giovanni De Cesare, Shun Nomura
Flume experiments are conducted to model sediment-laden density currents with continuous suspension supply. The initial density covers 1008, 1016, and 1032 kg/m3 and the bottom slope at 5.0 %. Sediment deposition profiles along the experimental flume are m ...
2018Hydrodynamics of mountain-river confluences and its relationship to sediment transport
Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña
Mountain confluences are characterized by narrow and steep tributaries that provide important sediment load to the confluence, whereas themain channel supplies the dominant flow discharge. This results in a marked bed discordance between the tributary and ...
American Geophysical Union2017Prediction and forecast of Suspended Sediment Concentration (SSC) on the Upper Yangtze basin
Mário Jorge Rodrigues Pereira Da Franca, José Pedro Gamito de Saldanha Calado Matos
Sediment transport in suspension may represent 90% or more of the global annual flux of sediment. For instance, more than 99% of the sediment supplied to the sea by the Yangtze River is suspended load. Suspended load is an important component for understan ...
2017Impacts of wave and tidal forcing on 3D nearshore processes on natural beaches. Part I: Flow and turbulence fields
David Andrew Barry, Roham Bakhtyar
The major objective of this study was to develop further understanding of 3D nearshore hydrodynamics under a variety of wave and tidal forcing conditions. The main tool used was a comprehensive 3D numerical model – combining the flow module of Delft3D with ...
Techno-Press2016Impacts of wave and tidal forcing on 3D nearshore processes on natural beaches. Part II. Sediment transport
David Andrew Barry, Roham Bakhtyar
This is the second of two papers on the 3D numerical modeling of nearshore hydro- and morphodynamics. In Part I, the focus was on surf and swash zone hydrodynamics in the cross-shore and longshore directions. Here, we consider nearshore processes with an e ...
Techno-Press2016Assessing the Hydro-Morphodynamic Response of a Beach Protected by Detached, Impermeable, Submerged Breakwaters: A Numerical Approach
Coastal areas host a large fraction of the world's population and are exposed to natural extreme events, which are a serious threat to human life, as well as to economies. For this reason, sea storms are increasingly the object of studies, and the design o ...
Coastal Education & Research Foundation2016Assessment of the performance of numerical modeling in reproducing a replenishment of sediments in a water-worked channel
Anton Schleiss, Carmelo Juez Jiménez, Elena Battisacco
The artificial replenishment of sediment is used as a method to re-establish sediment continuity down- stream of a dam. However, the impact of this technique on the hydraulics conditions, and resulting bed morphology, is yet to be understood. Several numer ...
