Hi Sebastian!
I am a scientist who studies soil water erosion in Argentina. This occurs due to deforestation, and consequent replacement of forests by crops, among other factors. With the results of my research I would like to present my model in a dynamic way, as it appears in your demo. It would be a real terrain (I have the digital elevation model), with real erosion, real weather conditions, etc. Do you think we could develop something like that?
