Abstract
This paper gives the complete numerical schemes implementing the main 
physical laws proposed in landscape evolution models (LEMs). These laws 
can be modeled by a system of three partial differential equations 
governing water runoff, stream incision, hill slope evolution and 
sedimentation. The goal of the presented algorithm, code and online demo 
is to be able to test these equations on digital elevation models (DEMs) 
of any resolution, and to illustrate its potential to simulate the fine 
structure of the river network, and to understand the landscape 
morphology and its causes. The equations simulate plausible evolutions. 
We illustrate experiments on DEMs of several sites, including one site, 
La Réunion where the DEM is given at three different resolutions: the 
SRTM resolution (90m), and then 12m and 4m on DEMs derived from several 
Pléiades pairs. Other many DEMs are proposed in the online demo, which 
allows to upload and tests other DEMs.
