Filtration of broadly graded cohesive dispersive base soils
Dispersive soils are highly susceptible to erosion, particularly when they are used as a base
soil for the core of an earth dam. To prevent migration of the core material, the required filter …

An assessment of veracity of filter criteria for earth dams
The core of an earth dam is normally made of clayey base soils and protected by a sandy
filter. Designing the filter can be very challenging considering the various criteria established …

The effects of soil erosion characteristics on critical filter design in embankment dams
The commonly accepted criteria available for a critical filter design are considered
independent from soil erodibility and make no reference to soil erosion properties. This …
