TopoToolbox 2 – MATLAB-based software for topographic analysis and modeling in Earth surface sciences
TL;DR: The introduction of a novel technique to store flow directions as topologically ordered vectors of indices enables calculation of flow-related attributes such as flow accumulation ∼20 times faster than conventional algorithms while at the same time reducing memory overhead to 33% of that required by the previous version.

Short Communication: TopoToolbox 2 – MATLAB-based software for topographic analysis and modeling in Earth surface sciences
TL;DR: TopoToolbox as discussed by the authors is a MATLAB program for the analysis of digital elevation models (DEMs) that adopts an object-oriented programming (OOP) approach to work with gridded DEMs and derived data such as flow directions and stream networks.

Dynamic reorganization of river basins.
TL;DR: This work analyzed maps of a proxy for river elevation and horizontal movement of river drainage divides across three large river systems in China, Taiwan, and the United States, finding the Loess Plateau is close to geometric equilibrium, with χ exhibiting nearly equal values across water divides.

The stream power river incision model: evidence, theory and beyond
TL;DR: All published incising river datasets away from knickpoints or knickzones are in a regime dominated by threshold effects requiring an explicit upscaling of flood stochasticity neglected in the standard SPIM and other incision models, shown here to have a narrow range of validity.

Solutions of the stream power equation and application to the evolution of river longitudinal profiles
Leigh H. Royden,J. Taylor Perron +1 more
TL;DR: In this article, a non-dimensional stream power equation is used to transform river profiles in steady state with respect to uniform uplift into a straight line in dimensionless distance-elevation space, and a method that tracks the upstream migration of slope patches, which are mathematical entities that carry information about downstream river states, provides a basis for constructing analytical solutions.

Dynamics of the stream‐power river incision model: Implications for height limits of mountain ranges, landscape response timescales, and research needs
TL;DR: In this article, the authors explore the stream power erosion model in an effort to elucidate its consequences in terms of large-scale topographic (fluvial) relief and its sensitivity to tectonic and climatic forcing.

Tectonics from topography: Procedures, promise, and pitfalls
Cameron Wobus,Kelin X. Whipple,Eric Kirby,Noah P. Snyder,Joel P. L. Johnson,Katerina Spyropolou,Benjamin T. Crosby,Daniel Sheehan +7 more
TL;DR: In this article, a method for extracting topographic indices of longitudinal profi le shape and character from digital topographic data is described, which can then be used to delineate breaks in scaling that may be associated with tectonic boundaries.

Bedrock rivers and the geomorphology of active orogens
TL;DR: The results of intense research in the past decade are reviewed in this article, with the aim of highlighting remaining unknowns and suggesting fruitful avenues for further research, including the role of climate-driven denudation in the evolution of orogens.

Landscape response to tectonic forcing: Digital elevation model analysis of stream profiles in the Mendocino triple junction region, northern California
TL;DR: In this article, the authors evaluate and calibrate the shear stress (or similar unit stream-power) bedrock-incision model by studying stream profiles in a tectonically active mountain range.

TL;DR: In this paper, the erosion rate was proportional to the 4/9ths power of drainage area and the 2/3rds power of gradient in sand-bed alluvial channels.
