The proximity to a waterway is only a small part of the susceptability of an area to flooding.

only flooding ive ever seen around here was on the rivers and from storm surges. im no expert, just going on experience.

That is true, but only in a general sense. <begin making up numbers mode> Say you had a coastal area. The coastline is 2 feet above average sea level. The elevation increases at .75 foot per mile for 30 miles inland. Now, take a cat4 hurricane pushing a 4.5 foot storm surge.
1) You have the surge itself, which will be 2.5 deep at the coast (on *average*).
2) Said surge is being pushed by 140mph winds, driving it deep inland
3) At the same time as the storm surge, you have a heavy rain falling both on the coast and inland. This rain causes direct flooding. It also runs downslope, back towards the waterway.
That is just a simple scenerio. The reality is more complex as terrain is extremely irregular.

yeah i know all that. been a while since ive been to mississippi, but most places that got hit with all that are still pretty low lying. the land slopes up very gently.
around here, the land slopes up pretty steeply in comparison to the water. as soon as you cross the bay on our side, you go up a ~25 foot , .5mile hill. same on the other side, and scenic hwy (hwy 90) sits on top of a bluff of about ~50ft. that has a lot to do with helping the rain water drain out. but if youre on the beach, bay, or river, your pretty much facked.
