We are very excited to share our new website and rebranding. The website unifies our content and gives the community additional capabilities in a modern interface. Don't forget to sign up for our forum to learn about new features as we roll them out.

Research Highlight

A snapshot of an evolving asymmetric rift model at 12 Myr. The FastScape surface is colored by topography, and additionally shows the drainage area (blue to white) and erosion rate (white to black). The FastScape surface topography is averaged along the Y-direction and sent back to ASPECT at each timestep. [cont]

ASPECT: surface processes and basin formation through a two-way coupling with FastScape

The FastScape-ASPECT coupling is a two-way coupling that allows the landscape evolution model FastScape to deform the surface of ASPECT. Geodynamic models commonly simulate surface motions by using either a free surface or a sticky air layer. Either method can produce unrealistic highs or lows in the topography because they do not account for erosional and depositional processes that redistribute surface material through time. This redistribution not only helps obtain realistic topographies, but the change in surface loading can have widespread effects on model evolution, such as .... [cont]
