A landscape's sediment grain size distribution is the product of, and an important influence
on, earth surface processes and landscape evolution. Grains can be large enough that the …

Sediment grain size links sediment production, weathering, and fining from fractured
bedrock on hillslopes to river incision and landscape relief. Yet models of sediment grain …

Landslides are the main source of sediment in most mountain ranges. Rivers then act as
conveyor belts, evacuating landslide-derived sediment. Sediment dynamics are known to …

Feedbacks between surface and deep Earth processes in collisional mountain belts depend
on how erosion and topographic relief vary in space and time. One outstanding unknown …

Landscape evolution models can be used to assess the impact of rainfall variability on
bedrock river incision over millennial timescales. However, isolating the role of rainfall …

Rivers limit the maximum elevation of active mountain belts, control the coupling between
climate and tectonic processes, and archive the pace and tempo of fault-related rock uplift …

Despite considerable community effort, there is no general set of equations to model long‐
term landscape evolution. In order to determine a suitable set of landscape evolution …

Geologists frequently debate the origin of iconic river canyons, as well as the extent to which
they record climatic and tectonic signals. Fluvial and hillslope processes work in concert to …

Establishing that climate exerts an important general influence on topography in tectonically
active settings has proven an elusive goal. Here, we show that climates ranging from arid to …

Large boulders, ca. 10 m in diameter or more, commonly linger in Himalayan river channels.
In many cases, their lithology is consistent with source areas located more than 10 km …
