Influence of mantle flow on the drainage of eastern Australia since the Jurassic Period
Using our geomorphological model (Badlands) forced with dynamic topography, we investigate the evolution of australian landscape over the last 150 Ma. The models quantify the time dependence of erosion and deposition, as well as the evolution of catchment dynamics, drainage capture and drainage network reorganisation.

Badlands: An open-source, flexible and parallel framework to study landscape dynamics
In this paper we present a landscape evolution model able to simulate erosion, deposition, diffusion and flexure. The code is parallelised based on a sub-catchment partitioning approach. Models of delta stratigraphic evolution under sea-level fluctuations as well as mountain belts topographic evolution with climatic changes showcase the capabilities of the code.

Combined hillslope diffusion and sediment transport simulation applied to landscape dynamics modelling
We present a new numerical approach for simulating geomorphic and stratigraphic processes that combines open-channel flow with non-uniform sediment transport law and semi-empirical diffusive mass wasting. It is designed to facilitate modelling of surface processes across multiple space- and time-scales, and under a variety of environmental and tectonic conditions. In the implementation, the resolution of flow dynamics is made on a triangulated grid automatically mapped and adaptively remeshed over a regular orthogonal stratigraphic mesh. These new methods reduce computational time while preserving stability and accuracy of the physical solutions.
