How rivers react to large earthquakes: Evidence from central Taiwan
Earthquakes and bedrock river incision are fundamental processes in the evolution of tectonically active landscapes, yet little work has focused on understanding how a bedrock river responds to aExpand

Fractional dispersion in a sand bed river
[1] Random walk models of fluvial bed load transport use probability distributions to describe the distance a grain travels during an episode of transport and the time it rests after deposition.Expand

Numerical and analytical models of cosmogenic radionuclide dynamics in landslide-dominated drainage basins
[1] In many tectonically active regions on Earth, landslides dominate sediment delivery to channels. While cosmogenic radionuclides (CRN) represent a valuable tool to document basin-averaged erosionExpand

Statistical treatment of fluvial dose distributions from southern Colorado arroyo deposits
Abstract Many of the small-scale arroyo systems found across southern Colorado contain well-preserved sedimentary records of prehistoric fluvial erosion and aggradation epicycles. In the followingExpand

Trouble with diffusion: Reassessing hillslope erosion laws with a particle-based model
[1] Many geomorphic systems involve a broad distribution of grain motion length scales, ranging from a few particle diameters to the length of an entire hillslope or stream. Studies of analogousExpand

Formation timescales of large Martian valley networks
Abstract Assessing timescales for formation of the ancient Martian valley networks is key to interpreting the early climate on Mars. We determined the likely formation times for seven of the largestExpand

Does climate change create distinctive patterns of landscape incision
[1] Incised fluvial systems are typically interpreted as recording geologically recent changes in either climate or tectonics. However, few diagnostic tools exist to evaluate whether particularExpand

Modeling the effects of vegetation‐erosion coupling on landscape evolution
[1] From rainfall interception at the canopy to added soil cohesion within the root zone, plants play a significant role in directing local geomorphic dynamics, and vice versa. The consequences atExpand

Creative computing with Landlab: an open-source toolkit for building, coupling, and exploring two-dimensional numerical models of Earth-surface dynamics
Landlab is an open-source software framework explicitly designed to accelerate the development of new process models by providing (1) a set of tools and existing grid structures – including both regular and irregular grids – to make it faster and easier to develop new process components, or numerical implementations of physical processes; (2) a suite of stable, modular, and interoperable process components that can be combined to create an integrated model.

Implications of the shear stress river incision model for the timescale of postorogenic decay of topography
[1] The reason for the survival of mountainous topography in ancient orogenic belts is a long-standing problem in geomorphology and geodynamics. We explore the geomorphologic controls on theExpand
