TREMP is a numerical model coded in C used to simulate the development of the Eocene Tremp foreland basin in the Spanish Pyrenees. It is based on the GOLEM (Tucker) landscape evolution modelling code, which is extended with: Length Scales and Resolution Constraints:
The model spatial dimensions are 75 x 75 km, using rectangular grid cells of 100-500 m width. Vertical stratigraphic resolution is between the 0-1.5 m, or 1000 yrs of equivalent sedimentation. Depending on memory available on your PC, every gridcell holds about 1000 stratigraphic layers.

Time Scales and Resolution Constraints:
Computational time steps are 10-50 yrs and the maximum simulation time worked with ~ 3 Myr.

Numerical limitations and issues:
Available system memory to store 3D stratigraphy is a limiting factor.

Key Output:
3D stratigraphy (channel belt voxels, fence-diagrams, synthetic wells), basin relief, drainage patterns, process-specific erosion and sedimentation rates.
