Water model in Amber topology file

[saka]

I have a .top and .crd files of a receptor-ligand system in a cubic box of water created with Amber and xLeap.

It's not me who created the system and I would like to know if the .top file specifies the water model used ? I looked for keywords like 'WATER' and 'MODEL' in the .top file but didn't find matches.

What does this have to do with physics?
