Hey if you can't keep your story straight thats not my problem. I have provided the quote that shows you have made 2 conflictng statements
Your statement indicates you don't understand what I said
I will try to explain...again
they are NOT conflicting comments....
The rain that fell was a 1:200 year event(engineering terminology).....
More rain fell in 2011 than in 1974.....but the river level did not get as high this time....FACT!!
Have a look at levels on Regatta Hotel next time you are in Brisbane!
Ok you say it's a conflicting statement....but it isn't...
WHY?
Something happened between 1974 and 2011 to change the outcome....
What was it??
THEY...THE GOVERNMENT BUILT A F#~£|€? BIG DAM called Wivenhoe!.....this reduced the amount of water that flowed into the Brisbane River and reduced the potential flood level by 2m+ by storing the additional water and letting it out over several days AFTER THE RAIN HAD STOPPED
The flood was reduced in level....but it lasted longer
Perhaps that is a hard concept to understand.....??
I can't explain it any simpler....and I'm getting sick of repeating myself
If you still can't work it out....tough....you never will!
Goggle "1:100 year event hydraulic engineering" and see what you get!
Perhaps others may explain it better!
