Design Standards No. 13. Embankment Dams. Chapter 5. Protective Filters
The standard earth dams guideline is applicable to naturally occurring earth materials or to filters manufactured from such natural earth materials by grading, screening, and crushing. These filter criteria can be applied to the design of a wide variety of filters and drains that are included as elements specified for any hydraulic structure where excessive uplift pressures may lead to particle migration, boiling, and piping; where seepage flows require control and direction; where the phreatic surface must be controlled below a certain level; where exit gradients must be reduced to an acceptable maximum; where reduction of pore water pressures are required; and where erosion protection is necessary. Interconnected filters become an internal drainage system that functions to protect the structure being drained.
