Where is my car leaking and what damage could it do. no glass breakage

What is your question?

my car leaks really badly from somewhere around the hood and it comes in through the bottom. I wrecked it and they didn't fix it correctly. now it won't start and I just put a new battery in it do you have any ideas on what the water could have damaged I have been driving it like this for about a year and it always starts it just has a lot of water inside
