I'm sorry, but you are just flat out wrong there. It's flooded due to sever rainfall events that have occurred within the watershed.
Well, I was there when one happened. The basements of several buildings had standing water... the hospitals had flooded levels... and if by severe rainfall, you mean rainfall associated with storm surge from a Hurricane, then you're correct.... in part because storm surge keeps upstream water from being able to flow down. Otherwise, I'll stand by my personal experience and knowledge. I was there when it happened at Rice.
Ham, you weren't at Rice when it was flooded due to storm surge, because that has never happened.
Take for example the flooding from TS Allison, which filled the basements of the Med Center and was the largest rainfall event in Houston until Harvey. The flooding it caused around Rice was due to the massive amount of rain it dropped upstream of the Med Center, not because of any effects that storm surge had on reducing the ability of the watershed to drain the water. The compounding effect of storm surge does NOT effect the entire watershed, it only effects a certain portion of it, which changes given the conditions (amount of storm surge, amount of rain, duration of rain, location of rain, etc.).
Also, the term "rainfall associated with storm surge" doesn't really make sense. Rainfall is associated with the hurricane, not the storm surge. Storm surge and rainfall have compound effects as I've been saying. When I say sever rainfall, I'm talking about the rate and total amount that falls over a given area/watershed.
Quote:Compound flooding from hurricanes and major storms in the TX-GC region does occur and has been the leading reason why many coastal communities experienced flooding outside the 100-yr floodplain during these storms. And the compound flooding hazard is why I keep harping on how beach front properties are not the only areas affected by sea level rise.
No ****. As I said numerous times, just because something isn't true 100% of the time doesn't mean that it isn't true often enough to be a good example for discussion. Clearly anything below the rising sea level is effectively at risk and lots of beach-front is on a cliff... but generally speaking, the statement holds true. You're arguing just to argue... as if it invalidates the point because it isn't true 100% of the time. [/quote]
Look, I started this line argument because all OO kept referencing when talking about sea level rise was how it would affect wealthy landowners on the beach. I tried to make it clear that those were not the only populations affected by sea level rise, and tried to explain why far more people than just wealth beach owners would be affected.
Quote:But the research I've been around found that the compound flooding we've experienced in Houston does not translate up to Rice University. If anything, Rice didn't flood during Ike or Harvey, but did during some of the holiday storms, where storm surge wasn't present. I can reach out to the researcher I worked with to get details on where the compound flooding effect was observed during Ike if you would like (not sure if they have evaluated Harvey).
You're still doing it!
As I said, I experienced it, before you were born I suspect... not meant as an insult just a frame of reference. Maybe they redirected the upstream water differently (like flooding Katy) in order to protect the med center. Other parts of Houston certainly flooded during Ike and Katrina... many of which wouldn't be similarly effected by even an 8 foot rise in sea levels. You can keep arguing, but you really can't get away from that very simple fact. You and your paper say (essentially) that if you want to know the impact of an 8 foot rise in sea levels, look at flooding maps of an 8 foot storm surge for a start. If you don't think that's what they say, then I guess we can disagree on that. I believe that if you want to know the effects of a gradual rise of 8 feet over 80 years, you look at a topographical map and 'cover' anything less than 8 feet above current sea levels that you can reasonably guess a 'path' to.

Honestly, I'm not sure what you're trying to get across here or what simple fact am I trying to get away from.
But this is another reason I think we're on different pages. I wasn't trying to argue that the effect of an 8-ft sea level rise is equal to an 8-ft of storm surge. I was arguing multiple points.
1) Primarily that sea level rise will affect more than just those with beach front property. I can see how you might have been confused when I said you could look at the effects of storm surge to understand that more than just beach front property would be affected. My point with that was not to indicate that you can treat the two as the same thing, but rather that these coastal flooding events do not just affect those directly on the beach (which is what was the main focus of the argument).
2) That sea level rise will increase the effect of storm surge, and in ways that aren't 1:1, but in ways that compound.
I deleted the rest of the comments because I don't think they advance anything.
