Achieving Optimal Locomotion using Self-Generated Waves
D. O'Donovan, M. D. Bustamante, O. Devauchelle +1
An oscillating body floating at the water surface produces a wave-field of self-generated waves. When the oscillation induces a difference in fore-aft wave amplitude squared, these…
On wave-driven propulsion
GP Benham, O Devauchelle, SJ Thomson
A theory is presented for wave-driven propulsion of floating bodies driven into oscillation at the fluid interface. By coupling the equations of motion of the body to a quasi-poten…
Soft matter physics of the ground beneath our feet
Anne Voigtländer, Morgane Houssais, Karol A. Bacik +24
Inspired by presentations by the authors during a workshop organized at the Princeton Center for Theoretical Science (PCTS) in January 2022, we present a perspective on some of the…
Sediment load determines the shape of rivers
Predrag Popović, Olivier Devauchelle, Anaïs Abramian +1
Understanding how rivers adjust to the sediment load they carry is critical to predicting the evolution of landscapes. Presently, however, no physically based model reliably captur…
Gunwale bobbing
GP Benham, O Devauchelle, SW Morris +1
It has been shown experimentally that small droplets, bouncing on a vibrated liquid bath, can "walk" across the surface due to their interaction with their own wave-field. Gunwale…
Boltzmann distribution of sediment transport
A. Abramian, O. Devauchelle, G. Seizilles +1
The coupling of sediment transport with the flow that drives it allows rivers to shape their own bed. Cross-stream fluxes of sediment play a crucial, yet poorly understood, role in…
Laplacian networks: growth, local symmetry and shape optimization
O. Devauchelle, P. Szymczak, M. Pecelerowicz +3
Inspired by river networks and other structures formed by Laplacian growth, we use the Loewner equation to investigate the growth of a network of thin fingers in a diffusion field.…
Where do rivers grow? Path selection and growth in a harmonic field
Yossi Cohen, Olivier Devauchelle, Hansjorg F. Seybold +3
River networks exhibit a complex ramified structure that has inspired decades of studies. Yet, an understanding of the propagation of a single stream remains elusive. Here we invok…
Shape and dynamics of seepage erosion in a horizontal granular bed
Michael Berhanu, Alexander Petroff, Olivier Devauchelle +2
We investigate erosion patterns observed in a horizontal granular bed resulting from seepage of water motivated by observation of beach rills and channel growth in larger scale lan…
Geometry of Valley Growth
Alexander P. Petroff, Olivier Devauchelle, Daniel M. Abrams +3
Although amphitheater-shaped valley heads can be cut by groundwater flows emerging from springs, recent geological evidence suggests that other processes may also produce similar f…
