soil - self filtering criteria
soil - self filtering criteria
(OP)
I am working on a paper about flow of water through soil. Someone told me that there is a "self filtering" criteria that is based on the grainsize distribution of the soil. Does anyone know of it and have a reference.

And you can also look at the COE specs -
Please see FAQ731-376 for great suggestions on how to make the best use of Eng-Tips Fora. See FAQ158-922 for recommendations regarding the question, "How Do You Evaluate Fill Settlement Beneath Structures?"

Probably the best reference on this topic is Lafleur et al (1989) "Filtration of Broadly Graded Cohesionless Soils" ASCE JGE, 115(12) pp 1747-1768. For basic understanding of filters (or seepage in general), I concur with Focht3 that Cedergren can't be beat. If dealing with geosynth' filters, check Koerner's book or Holtz, Christopher and Berg (1997). For some great design guidance check out "Embankment Dams Granular Filters and Drains" ICOLD Bulletin 95.
