Hi,

Could you give me more precisions on the recursive aspect and its 
limits, for exemple do you think that your model could be applied to a 
nord europe hydrologic setting ? The testcase shown on your website is a 
wadi bordering the Jordan rift valley which is quite a different beast.

I'm also curious about how far back in time you did push your experiment 
and on the way you did extrapolate the neolithic period settings.
