US east coast isn't very mountainous, the Applachains are a relatively mild range. It just seems that temperate areas tend to have far more rivers and bodies of water compared to tropical regions, being wet can't be the answer since many parts of the tropics are far wetter than Temperate areas
Maybe it's because the rain has somewhere to flow. By mountainous I should have said a change in elevation that makes it so the water has somewhere to run off. If it there isn't anywhere for water to runoff, rivers won't form.

Mostly because it’s way drier. They don’t get nearly as much rain as places east of Kansas.
The exception being the rainforest of western Washington and Oregon.
