Crossing the river

[Zuru84]

I know that army attacking another army when crossing the river is getting huge penalty.
Where can I check if my army will cross the river? Or where can I see on which type of terrain i will be fighting with my enemy (any chance for a screenshot)?

You can see the terrain by hovering your mouse over the county. It'll tell you the terrain in the bottom left corner.
The river status is shown on the county view.

Under the main holding is a little picture of a river. Hover over that, and it'll tell you what counties' borders have a river

1.Is it possible that I can see river on the map but in the province there is no info about it?
2.In this case I understand I will not receive any penalty?
3.Also, during the battle can I check what penalties my army is receiving?

1: Possible that the river is only in the province itself, and not actually on the border.
2: Should be no penelty if there is nothing listed there no.
3: Yes. The icons at the arrows: http://i.imgur.com/dSMJ6wi.png Again, hover over
Sorry for the quality, I'm pulling these off internet and adding commentary:

Terrain is crucial for battles. I always like to know the terrain before battling.

As Aragon, I would attack 8000 Occitans with 6000 Catalans, if the Pyrenees were on my side, I'd win.

As an update that I just remembered: you can also see army bonus/penelties involved in NPC armies fighting:
