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.

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 authors analyze the implications of various sediment-flux-dependent incision models for large-scale topography, in an attempt to identify quantifiable and diagnostic differences between models that could be detected from topographic data or from the transient responses of perturbed systems and explain the apparent ubiquity of mixed bedrock-alluvial channels in active orogens.

TL;DR: In this paper, the consequences of several different hillslope process laws are explored in a series of experiments with a numerical model of drainage basin evolution, including a simple diffusive-advective process transition, a runoff generation threshold, an erosion threshold, and two types of threshold activated landsliding.

TL;DR: In this article, the sensitivity of watersheds to climate change is analyzed using a physically based model of drainage basin evolution, which simulates basin evolution under the action of weathering processes, hillslope transport, and fluvial bedrock erosion and sediment transport.
