,• BASIC COMPONENTS OF AN EARTH DAM
• Foundation
• Core or (membrane)
• Shell
• Transition Filter
• Internal Drain
• Toe Drain
• Cut off
• Wave protection
• Rip rap protection
• Crest
, • FOUNDATION
• It consists of either earth or rock and provides a support for the emba
and resists both vertical and horizontal loads.
• It also resists under seepage on the flow of water beneath the dam.
• TRANSITION FILTER
• In core dams, a transition filter between the core and shell is generally
provided to prevent the migration of the fine grained core materials in
pores of the coarse grained shell materials.
• In case of difference in particle sizes of the materials of the core and s
small then transition filter is omitted but in case of clay cover and rock
gravel shell, a transition filter is necessarily provided.
