Stage Storage for a horizontal sloped pipe

[bdavila]

Does anyone know of link to a free website that has a user friendly program or spreadsheet to compute the stage storage for a horizontal sloped pipe?
Thanks

Would you explain the meaning of "stage storage"?

This was discussed recently in another forum:

Stage - storage calculations are required for stormwater management volumes. As the pipe fills up there is a loss in volume if the horizontal pipe is sloped. In my case I have a 10' dia pipe so my stage elevations would be in one foot intervals. I need the storage for each of the stage elevations.

"Stage Storage" means "at this elevation, the sloped pipe stores this volume, at this higher elevation it stores this much more volume, and now we make a table relating stage (elevation) to storage (volume)."


I've got an excel sheet that'll do exactly what you need. Shoot me an email.

Bimr, Thanks for the lead but I had tried the link to ADS in the other forum and it no longer works.

For circular pipes FHWA's Visual Urban (HEC22 - Free DL at FHWA) has an option. If you are using Horiz Elip pipe then you need to refer to a partial flow nomograph and creat your own stage vs. area and compute the volume. I just had to do this for a 38x24 HERCP.

You can do it easily with HydroCAD - including the free Sampler. Just create a pond with a pipe storage element and set the parameters. It will handle round, arch, elliptical, and box pipe.
