Description :
Cosmogenic nuclides have provided a powerful tool for determining rates of landscape erosion. A probabilistic formulation for the conservation of cosmogenic nuclides is derived so as to include the effect of the fluctuations. Although the real-world applicability of the current model is limited to weathering- and transport-limited systems, and is particularly well-suited to badlands, formulating erosion as a kinematic wave function allows the development of more sophisticated models of landscape development. The AA. outline how the model can be generalized to basins dominated by deep-seated landslides and to transport-limited, soil-mantled hillslopes.
