Model domain	Terrestrial, Geodynamic
One-line model description	tAo is a software designed to model the interplay between lithosphere flexure and surface transport (erosion/sedimentation), particularly during the formation of orogens and foreland sedimentary basins (see details).
Extended model description	This pseudo-2D (cross-section, 1 independent variable x) numerical model permits calculating 1D lithospheric flexure with different rheologies, in combination with faulting, loading, and erosion/deposition. The programs are developed in C for Linux platforms, graphic output is produced using GMT scripts, and standard PCs match the CPU and memory requirements. The software is available for free under a GPL license.

Describe processes represented by the model	tAo is an open-source software designed to model the interplay between lithosphere flexure and surface transport (erosion/sedimentation), particularly during the formation of orogens and foreland sedimentary basins (see details). This 2D (cross-section) numerical model calculates 1D lithospheric flexure with different rheologies, in combination with fault kinematics, other isostatic loads, and erosion/deposition. Erosion models include both constant-rate and climate-based approaches. The programs are developed in C for Linux platforms, graphic output is produced using GMT scripts, and standard PCs match the CPU and memory requirements. The software is available under a GPL license.
Describe key physical parameters and equations
Describe length scale and resolution constraints	From continental to regional scale (>50 km). Up to a few thousand cells are well handled.
Describe time scale and resolution constraints	About 1kyr for surface processes; 200kyr for tectonic/ isostatic processes.
Describe any numerical limitations and issues
