Back during the Flood of 2016 there was long thread about the flood.

There was a poster who was exceptional at predicting the Amite Levels, and he posted how he did it. I don't remember his formula, but he was much more accurate than the NOAA site.


Anyone remember this conversation? I have a more vested interest than I did 4 years ago.

He was predicting all the back flowing basically to the hour because he was following crests. Dude was a champ.

Just for conversation sake, let's remember that on Friday at 4pm, NOAA's high prediction at Port Vincent is Monday at 4pm at 7.9 feet.

This is a far more complex situation than 2016 to predict. You have tides and tidal surges from the Gulf. Significant S/SE winds pushing water up the river. Significant rainfall from up North already in the river and another dump to come in the next 24 hours.

Once the wind is down and "all" the rain is in the river it becomes easier to predict.

I appreciate those facts Obtuse1, but I'd still like to hear how that guy was able to predict so accurately. Just for my future use.

I appreciate the NOAA site, as it's really all I know of, but from my experience of watching it pretty closely over the last year, it's prediction part of it's graph really just isn't very accurate.

That’s kind of the point, though. It can only be as accurate as the rainfall totals. All the hydrology expertise in the world doesn’t help if you don’t know how much rain is going to fall. That’s why the river stage predictions are much more accurate after a weather event.

Someone mentioned in another thread he had access to models that no one on the OT has in the Delta thread.

Don’t know the truth of the matter

Right. And the backwater flooding from the Amite that he predicted was almost after the rainfall north was over.

Unless there is a ton of rain in the upper Amite river basin, the Diversion Canal will only be rising, at most, another 6 inches

It was supernovasky. He is now a she though. She posts on Reddit still. I've DMed her asking if she'd consider returning.

The model that was built a couple of years ago will be far more accurate, but it's not really a predictive model. The resolution of the model is just too high for most workstations to run quickly. They are probably already running scenarios on cloud servers based on what entered the river overnight.

The surge will likely be gone by the time that the peak heads downstream, too. Frankly, I'm not very concerned about anything in the same stratosphere as 2016.
