Earth's terrestrial topography evolves in response to the interaction of tectonics, climate, and
lithology. Recent discoveries suggest that the grain size of sediments produced on hillslopes …

River incision into bedrock drives the topographic evolution of mountainous terrain and may
link climate, tectonics, and topography over geologic time scales. Despite its importance, the …

The stream power incision model (SPIM) is a cornerstone of quantitative geomorphology. It
states that river incision rate is the product of drainage area and channel slope raised to the …

Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea
level do not lie within a drainage basin. Even points distant from the nearest channel are …

We provide field evidence for the role of bedload in driving fluvial incision and knickpoint
propagation. Using aerial photographs, field surveys, and hydrological data, we constrain …

A major control on bedrock incision is the interaction between alluvial cover and erosive
mobile grains. The extent of alluvial cover is typically predicted as a function of relative …

Understanding the physical processes driving bedrock channel formation is essential for
interpreting and predicting the evolution of mountain landscapes. Here we analyze bedrock …

Sediment transport is an intrinsically stochastic process, and measurement of bed load in
the environment is further complicated by the unsteady nature of river flooding. Here we …

Abstract The Yarlung Tsangpo River, which flows from west to east across the southern part
of the Tibetan Plateau, is the longest river on the plateau and an important center for human …

Results from computational morphodynamics modeling of coupled flow–bed–sediment
systems are described for 10 applications as a review of recent advances in the field. Each …
