Active Hillslope

Active Hillslope (2026)

Can sparse biological active matter produce persistent creeping hillslope below its critical angle?

Percolation transition for river networks

Percolation transition for river networks (2026)

Coupling Scheidegger's random-walk drainage network to a minimal rainfall-and-storage rule yields a directed spanning transition.

Bulk-Dissipative Sandpile

Bulk-Dissipative Sandpile (2026)

A Bak–Tang–Wiesenfeld sandpile where toppled grains leave the system.

Meanderlife

Meanderlife (2026)

Water attracts biological agents, but water is dynamic. As a river, it meanders. Here we study how agents behave when the water they depend on keeps moving.

Chaotic rivers

Meander Cutoffs Induce Chaos (2025)

We show that neck cutoffs alone are sufficient to produce chaotic dynamics in kinematic river channel evolution, imposing a finite predictability horizon on planform modeling.

Ucayali River erosion risk map

Geomorphic Risk Maps for River Migration (2024)

We use probabilistic modeling to map where the Ucayali River is likely to erode over the next 50 years.
