Soil erosion is generally recognized as the dominant process of land degradation. The
formation and expansion of gullies is often a highly significant process of soil erosion …

For many years, scientists have tried to understand, describe and quantify water and
sediment fluxes, with associated substances like pollutants, at multiple scales. In the past …

Topographically complex regions on land and in the oceans feature hotspots of biodiversity
that reflect geological influences on ecological and evolutionary processes. Over geologic …

We present a coevolutionary view of hydrologic systems, revolving around feedbacks
between environmental and social processes operating across different time scales. This …

▪ Abstract Bedrock rivers set much of the relief structure of active orogens and dictate rates
and patterns of denudation. Quantitative understanding of the role of climate-driven …

Efforts to extract information about climate and tectonics from topography commonly assume
that river networks are static. Drainage divides can migrate through time, however, and …

Geomorphology is currently in a period of resurgence as we seek to explain the diversity,
origins and dynamics of terrain on the Earth and other planets in an era of increased …

Develo** a quantitative understanding of the factors that control the rate of river incision
into bedrock is critical to studies of landscape evolution and the linkages between climate …

The ability to model surface processes and to couple them to both subsurface and
atmospheric regimes has proven invaluable to research in the Earth and planetary sciences …

Mechanistic theories of fluvial erosion are essential for quantifying large‐scale orogenic
denudation. We examine the topographic implications of two leading classes of river erosion …
