How rivers react to large earthquakes: Evidence from central Taiwan

B. Yanites, G. E. Tucker, K. Mueller, Y. Chen
Geology
1 July 2010

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 a… Expand

Fractional dispersion in a sand bed river

D. Bradley, G. E. Tucker, D. Benson
Physics
1 March 2010

[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

B. Yanites, G. E. Tucker, R. S. Anderson
Geology
1 March 2009

[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 erosion… Expand

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 following… Expand

Trouble with diffusion: Reassessing hillslope erosion laws with a particle-based model

G. E. Tucker, D. Bradley
Geology
1 March 2010

[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 analogous… Expand

Formation timescales of large Martian valley networks

M. T. Hoke, B. Hynek, G. E. Tucker
Geology
1 December 2011

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 largest… Expand

Does climate change create distinctive patterns of landscape incision

Cameron Wobus, G. E. Tucker, R. S. Anderson
Geology
1 December 2010

[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 particular… Expand

Modeling the effects of vegetation‐erosion coupling on landscape evolution

D. B. Collins, R. Bras, G. E. Tucker
Environmental Science
1 September 2004

[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 at… Expand

Creative computing with Landlab: an open-source toolkit for building, coupling, and exploring two-dimensional numerical models of Earth-surface dynamics

D. Hobley, J. M. Adams, +4 authors G. E. Tucker
Computer Science
14 September 2016

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

J. Baldwin, K. Whipple, G. E. Tucker
Geology
1 March 2003

[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 the… Expand
