It is worth noting that the coefficient m and n are fixed in this version and take the value 0.5 & 1 respectively.</br>diffusion: hillslope, stream and marine diffusion coefficients. hillslopeK sets the simple creep transport law which states that transport rate depends linearly on topographic gradient. River transported sediment trapped in inland depressions or internally draining basins are diffused using the coefficient (streamK). The marine sediment are transported based on a diffusion coefficient oceanK. The parameter maxIT specifies the maximum number of steps used for diffusing sediment during any given time interval dt.</br>Finally, you will need to specify the output folder:</br></br>output: with dir the directory name and the option makedir that gives the possible to delete any existing output folder with the same name (if set to False) or to create a new folder with the give dir name plus a number at the end (e.g. outputDir_1 if set to True)umber at the end (e.g. outputDir_1 if set to True)

eSCAPE is a parallel landscape evolution m … 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.</br></br>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).on changes and/or sea-level fluctuations). +
