confused about cooking an arm roast (beef)?

[MommyDOK]

I'm not much of a roaster. We don't have a working croc pot. I have a big arm roast and I did an online search. One recipe said to put water in the dutch oven half way. Another recipe said not to do that bc it will cook unevenly.

What to do? I'm confused. Thanks so much for any help or direction.

i put in enough water to cover the bottom, just so it won't burn. maybe 1/4 inch overthe bottom,
i also throw in a few quartered onions, big chunks of carrots, leeks, turnips, parsnips, whatever i have on hand
