Ah, right. Erosion is biased towards cardinal axes to some extent, yes...that's a side effect of the grid-based erosion algorithm, which samples points in those directions to gather data about surrounding sediment/water deposits.
The Terrain Erosion operator does actually have a hidden particle-based mode. You can only switch to that mode from MAXScript...but it's fully featured so you can play around with it and it won't have the same cardinal biases as grid-based mode. It has its own issues (it's tougher to fine-tune, tends to be slower, and has no presets)...but in your case it may get you closer to the results you want.
You can enable it for any Terrain Erosion operator through MAXScript like this:
Just replace "event_001" with the target event name.
Attached is a scene with it unlocked and a screenshot of the result. Eventually I may make this mode accessible through the normal UI...it's just hidden for the time being.
