That all depends on the size, age, species and maybe the health state of the bear and the crocodile.
A polar bear would win the fight on land if it clawed the crocodile's head and flipped its body to claw its stomach. In water, the crocodile would definitely win the fight.
The grizzly bear would maul the crocodile on land if the crocodile tried to attack the grizzly bear. Grizzly bears have strengths to kill a crocodile, no matter what species. In water, the crocodile may win.
On land the bear. In the water the crocodile .
Since most crocs are larger and more aggressive, I would go with the crocodile.
The kodiak bear would beat any type of crocodile on land as long as it sees the crocodile. Kodiak bears are very large and very powerful bears.
