If you don't have gutter systems and are getting flooding, then as mentioned got to have a drain system installed to collect the water once it gets to the ground.
Complicated subject but basically it is pref drain pipe laid in usually a gravel bed with a barrier under it. You have to get the water away from the house a decent distance and not allow it to soak into the ground. The first requirement if you are having any type of flooding problems.
They do make an edging type system that takes rain off the roof and changes its characteristics so it comes down more like a spray but if it soaks in, probably same problem.
If you want to collect rain water as in a rain barrel then the best way is via a gutter system. Say to water plants or use as a water source.
If you want the house to look good, as with mulch, gravel cover that is a separate subject.
Figure out what the real problem is and then start there.
