Filter Criteria 1

[ONENGINEER]

I am looking for a reference to check if a filter on a 1979 built earth dam meets the current criteria.

Already checked the D15f/D85b, D15f/D15b D15f/D50b and (D10/D90)f all within the criteria in text books and apparently per USBR(1994).

Could anybody let me know what is the latest publications from USBR or USCorps dealing with filter criteria for standard engineering methods.

Thank you.

OK...don't be lazy.
With a little research you would find that you need Design Manual No. 13, Chapter 5 published in 2011 by the USBR. Find it.
