eSCAPE is a parallel TIN-based landscape evolution model, built to simulate topography dynamic at various space and time scales. The model accounts for hillslope processes (soil creep using linear diffusion), fluvial incision (stream power law), spatially and temporally varying tectonics (horizontal & vertical displacements) and climatic forces (temporal and spatial precipitation changes and/or sea-level fluctuations).

Detailed Description

English {{currentDetailLanguage}} English

Quoted from:

  eSCAPE is a parallel landscape evolution model, built to simulate Earth surface dynamics at global scale and over geological times. The model is primarily designed to address problems related to geomorphology, hydrology, and stratigraphy, but it can also be used in related fields.

  eSCAPE accounts for both hillslope processes (soil creep using linear diffusion) and fluvial incision (stream power law). It can be forced using spatially and temporally varying tectonics (vertical displacements) and climatic conditions (precipitation changes and/or sea-level fluctuations). 

  The model computes flow accumulation using multiple flow direction over unstructured grids based on an adaptation of the implicit approach proposed by Richardson et al. (Richardson, Hill, & Perron, 2014). An extension of the parallel priority-flood depressionfilling algorithm from (Barnes, 2016) to unstructured mesh is used to simulate sedimentation in upland areas and internally drained basins. Marine sedimentation is based on a diffusion algorithm similar to the technique proposed in pybadlands (Salles, Ding, & Brocard, 2018). 

  eSCAPE is primarily designed to look at landscape dynamics at global scale but can also be used on much smaller spatial domains. A set of four examples is provided (eSCAPEdemo) and illustrates the main capabilities of the code from synthetic to regional applications as well as continental and global simulations.
