The blocking of river courses by mass movements is very common in mountainous areas
with deep and narrow valleys. Landslide dams may pose serious threats to people and their …

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 …

Bedrock river incision occurs only during floods large enough to mobilize sediment and
overcome substrate detachment thresholds. New data relating channel steepness and …

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 …

An important challenge in geomorphology is the reconciliation of the high fluvial incision
rates observed in tectonically active mountain ranges with the long-term preservation of …

The rate at which transient knickpoints propagate through a landscape fundamentally
controls the rate of geomorphic response to tectonic and climatic perturbation. Here we …

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 …

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 …

Extreme flood events have the potential to cause catastrophic landscape change in short
periods of time (100 to 103 h). However, their impacts are rarely considered in studies of …

Globally, glacial and paraglacial environments in mountains are vulnerable to the effects of
ongoing contemporary climate change (global warming), but monitoring of such systems …
