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 ...

Experimental Study on Bedload Transport and Bedforms: Behaviour and Interplay in Steep Turbulent Streams

Ivan Pascal

In mountain regions, steep streams play an important role in water and sediment connectivity. In these highly dynamic systems, water flow features, sediment fluxes and stream morphologies are tightly interlinked over a broad range of temporal and spatial s ...

The variability of antidune morphodynamics on steep slopes

Christophe Ancey, Ivan Pascal

Steep streams on rough beds are generally characterised by supercritical flow conditions under which antidunes can develop and migrate over time. In this paper, we present flume experiments that we conducted to investigate the variability of antidune geome ...

Estimating Mean Bedload Transport Rates and Their Uncertainty

Christophe Ancey, Ivan Pascal

Measuring bedload transport rates usually involves measuring the flux of sediment or collecting sediment during a certain interval of time Δt. Because bedload transport rates exhibit significant non‐Gaussian fluctuations, their time‐averaged rates depend a ...

Measuring Bedload Sediment Transport with an Acoustic Doppler Velocity Profiler

Koen Blanckaert, Joris Heyman

Acoustic Doppler velocity profilers (ADVP) measure the velocity simultaneously in a linear array of bins. They have been successfully used in the past to measure three-dimensional turbulent flow and the dynamics of suspended sediment. The capability of ADV ...

Fluorescent Probes for Plasma Membrane Proteins Based on Nile Red

Efthymia Prifti

Fluorescent probes are very important in basic research and in medicine, because of their sensitivity, versatility and quantitative capabilities. They allow the imaging of tissues or cellular compartments and the monitoring of biological events in vivo. An ...

Push-pull dioxaborine as fluorescent molecular rotor: far-red fluorogenic probe for ligand-receptor interactions

Iuliia Karpenko

Fluorescent solvatochromic dyes and molecular rotors have attracted considerable attention as fluorogenic probes because of background-free detection of biomolecules in live cells in no-wash conditions. Herein, we introduce a push-pull boron-containing (di ...
