Long-term patterns of hillslope erosion by earthquake-induced landslides shape mountain landscapes (2020)
Journal Article
Wang, J., Howarth, J. D., McClymont, E. L., Densmore, A. L., Fitzsimons, S. J., Croissant, T., …Hilton, R. G. (2020). Long-term patterns of hillslope erosion by earthquake-induced landslides shape mountain landscapes. Science Advances, 6(23), Article eaaz6446. https://doi.org/10.1126/sciadv.aaz6446

Widespread triggering of landslides by large storms or earthquakes is a dominant mechanism of erosion in mountain landscapes. If landslides occur repeatedly in particular locations within a mountain range, then they will dominate the landscape evolut...

Statistical modelling of co-seismic knickpoint formation and river response to fault slip (2019)
Journal Article
Steer, P., Croissant, T., Baynes, E., & Lague, D. (2019). Statistical modelling of co-seismic knickpoint formation and river response to fault slip. Earth Surface Dynamics, 7(3), 681-706. https://doi.org/10.5194/esurf-7-681-2019

Most landscape evolution models adopt the paradigm of constant and uniform uplift. It results that the role of fault activity and earthquakes on landscape building is understood under simplistic boundary conditions. Here, we develop a numerical model...

Seismic cycles, earthquakes, landslides and sediment fluxes: Linking tectonics to surface processes using a reduced-complexity model (2019)
Journal Article
Croissant, T., Steer, P., Lague, D., Davy, P., Jeandet, L., & Hilton, R. G. (2019). Seismic cycles, earthquakes, landslides and sediment fluxes: Linking tectonics to surface processes using a reduced-complexity model. Geomorphology, 339, 87-103. https://doi.org/10.1016/j.geomorph.2019.04.017

In tectonically active mountain ranges, landslides triggered by earthquakes mobilise large volumes of sediment that affect river dynamics. This sediment delivery can cause downstream changes in river geometry and transport capacity that affect the ri...

Carbon export from mountain forests enhanced by earthquake-triggered landslides over millennia (2018)
Journal Article
Frith, N., Hilton, R., Howarth, J., Gröcke, D., Fitzsimons, S., Croissant, T., …Densmore, A. (2018). Carbon export from mountain forests enhanced by earthquake-triggered landslides over millennia. Nature Geoscience, 11(10), 772-776. https://doi.org/10.1038/s41561-018-0216-3

Rapid ground accelerations during earthquakes can trigger landslides that disturb mountain forests and harvest carbon from soils and vegetation. Although infrequent over human timescales, these co-seismic landslides can set the rates of geomorphic pr...

Technical note: in situ measurement of flux and isotopic composition of CO2 released during oxidative weathering of sedimentary rocks (2018)
Journal Article
Soulet, G., Hilton, R., Garnett, M., Dellinger, M., Croissant, T., Ogrič, M., & Klotz, S. (2018). Technical note: in situ measurement of flux and isotopic composition of CO2 released during oxidative weathering of sedimentary rocks. Biogeosciences, 15(13), 4087-4102. https://doi.org/10.5194/bg-15-4087-2018

Oxidative weathering of sedimentary rocks can release carbon dioxide (CO2) to the atmosphere and is an important natural CO2 emission. Two mechanisms operate – the oxidation of sedimentary organic matter and the dissolution of carbonate minerals by s...

A precipiton method to calculate river hydrodynamics, with applications to flood prediction, landscape evolution models, and braiding instabilities (2017)
Journal Article

The “precipiton” method is a particle‐based approach that consists of routing elementary water volumes on top of topography with erosive and depositional actions. Here we present an original way to calculate both river depth and velocity from a metho...

In the past few decades, many studies have been dedicated to the understanding of the interactions between tectonics and erosion, in many instances through the use of numerical models of landscape evolution. Among the numerous parameterizations that... Read More about Constraining the stream power law: a novel approach combining a landscape evolution model and an inversion method.
