Gaea Experiment: Arid Landscape

Second project in the objective to look into the new update of Gaea.
I just discovered the "Crumble" node that creates erosion in a really specific way.
For the sand, a mix of "Thermal" and "Alluvium".
I wanted to generate some kind of hydrological flow that lets us think there used to be a river at some point.
Within this flow, the sand is also more wet to justify that this river bed is actually getting dryer by the time.
