RipRap - Maximum Tailwater Condition Block

[gspears]

This block should output a correctly sized riprap apron for a given pipe diameter (in feet) and a discharge value. I have pared down the available sizes to ranges that we use commonly in my area. I suggest doing the same; the block is kind of slow otherwise. Also, this block contains constraints, so it will only work with v2010 or greater.

Thank you for sharing this file. I've tweaked it a bit and created a Minimum Tailwater Condition version as well and since I didn't originate this, I figure I should share it back. I thought it made the most sense to keep these connected as things get lost on the internet when everyone says "just google it."

I added user parameters to take a user imputed D50 size (ft) and the density (pcf) and estimate the square yards of fabric and the tons of rip rap.

Wow. It's nice to see that someone found a use for this block that i posted six years ago. I completely forgot about this thing. Well, I'm glad it was useful.
