Where I grew up in Pearland they received 57 inches of rain through out the event.
Our house flooded in 1979 during Claudette. Durling Alicia we did not flood but had a lot of water in the yard, the winds blew most of the water away from the house.
The house flooded about a foot in the early 90's and about 4 ft in Alison ,but I had already moved to Kentucky. My parents sold and moved here in 2003, they got tired of flooding.
I feel for everyone there I have been there and done that.
One time in college we went to a mexican rest down the Gulf freeway from UH , while we were there it cam 7 inches of rain at UH and we could not get back.
K. P. Harrier blue streak 1 (8-28): blue streak 1 Will the UP bridge over the Brazos survive the flood this time ? I was thinking the same thing as you, blue streak 1, and was wondering about the Sunset Route’s recently revamped Brazos River Bridge. For those that think this forum or even this thread should be renamed “9-1-1” and that should guide the discussions, somehow I don’t think those at Kalmback would concur with them … While Houston is under water, the High Desert of Southern California is dry and hot, at 110 decrees. What a contrast is in this great nation! Take care, K.P.

There are unconfirmed reports that some floating top tanks have collasped tops downward due to so much rain on top. Since water is heavier than most petroleum products can imagine a tank not full would be prone to collaspe under too much water weight ? Any confirmation one way or the other ?

Thanks to Chris / CopCarSS for my avatar.
Murphy SidingI'm not sure I understand what a floating top tank is.
In this kind of tank the roof structures swims on top of the stored liquid. so the roof structure has no free span but is supported over the entire area.Regards, Volker

I'm not sure I understand what a floating top tank is. Wouldn't any tank made to store petroleum have some pitch to the top in order to drain water?

Can't believe anything built in the vicinity of the Gulf Coast hasn't been built with some pitch on the top surface and a drain system. While 50+ inch rain events aren't normal - 5 & 10 inch storms are commonplace and I don't believe anyone building structures expects the top surface of those structure to hold 'all' of the storm water - even at the lower accumulation totals.
On a roof pitched to the outside it depends if there is aparapet or not. With parapet the drain opening limits the flow rate. Without the water just overruns the roof edge.
With floating top tank you have a parapet without any openings as the roof level varies with amount of stored liquid. So the roof's drainage has to be sufficient:http://www.ansonindustry.com/uploads/allimg/Floatingrooftankstructure.jpg
So all depends on the rainfall it is designed for. And I'm quite sure it wasn't designed for Harvey's rainfall.Regards, Volker

I understand why the refineries were built in that location in the first place, however.....you would think they would relo the refineries further inland vs the constant repair and on/off switch every time a Hurricane comes by or flooding threatens. The constant on/off cycle appears to be a little stupifying to me.

Actually, I would have expected the reifineries and chemical plants to have built dykes for their plant's protection, at least against normal flooding situations. 50+ inches over 5 consecutive days is well beyond the norm.

Refineries are also tied to established infrastructure of pipelines, water transportation, and even rail at least for some outgoing traffic. Also there is much offshore and onshore production in the area. There are tie-ins between refineries and petrochemical plants.
Dikes and seawalls could help protect from seawater surges and up stream flooding, but 50" of rain over a square mile of refinery would probably overwhelm any pump design expectation.

120KGPM would almost handle it if the 50 inches are spread evenly over five days. That is a lot of pumping capacity, though, an acre-foot every 2.7 minutes. Of course, that is a lower bound on the necessary pumping capacity in any scenario putting 50 inches on the ground over a five-day stretch.

I suppose it is a similar situation in New Orleans which is below sea level, and all rainwater must be pumped out.
ChuckCobleigh120KGPM would almost handle it...
To put some perspective on that - it's around 100 fire engines worth of capacity...
And all that water has to go somewhere.

I don't know the American rules but in Germany rain water that was collected within the dikes of a tank farm has to go through a liquid seperator.
If the tank farm dike gets flooded from the outside it can be pumped out as it is considered contaminated on the outside.Regards, Volker

I don't know about other states, but in Michigan oil fields, crude oil tank battery dikes full of rain water need to be tested before being pumped out. Now days industrial sites must have stormwater management plans in place.
tree68And all that water has to go somewhere.
And that, as they say, is the real rub.
