Hi,
Do you have any tips for the best way to promote mixing in a potable water reservoir?
In this case, the reservoir I'm designing holds 1.0 million gallons (32' shell height, 74' diameter).
We used to use a reducer angled upward at the inlet (eg. 12" to 6" reducer to increase velocity)...
Hi,
I'm designing a 32-foot high, 0.5 MG reservoir in Seismic Zone 4 in California, and the geotech engineer has supplied us with three different design spectral graphs by 1) Campbell & Bozorgnia, 2) Boore, and 3) Sadigh. I've been instructed to use the most conservative of the three. Sadigh...

We're designing a large detention basin (10 acre site, 6.1 ac-ft of storage), with 2:1 side slopes.
Could someone give a summary of what each of the measures listed below is, including whether it is temporary or permanent, and compare the advantages and disadvantages of each? (For example...
I checked APWA and LA County standards for a standard headwall design, but didn't find anything. I've never designed a headwall before, but I would think it would be simple enough that there would be a standard design for it somewhere.
Does anyone know of a standard headwall design I could...
We're designing a detention basin with a 25' wide, 2' deep concrete inflow spillway, that will take a maximum inflow of 336 cfs during the 50 yr storm. The spillway flows into a concrete low flow swale at the floor of the basin. On either side of the spillway at the bottom of the slope in the...
