Transition zones/filters in earth and rockfill dams in the upstream and downstream shells are necessary, when the specified gradation criterion is not satisfied between two adjacent zones. When such zones/filters are placed on either side of the impervious core, they help to minimize failure by internal piping, cracking, etc, that may develop.
Well-compacted rockfill dams behave differently from those of early earth-rockfill dams. Therefore, the case histories are classified into two categories: well-compacted rockfill dams and early earth-rockfill dams. The effect of dam height on the seismic response distribution is discussed.
Rockfill dams, as one of the greatest geotechnical structures, are increasingly used because of their inherent flexibility, capacity to absorb large seismic energy, and their adaptability to various foundation conditions. The use of modern earth and rockfill moving equipment and locally available materials makes such dams economical as well.

This manual outlines the key components that will ensure the safety and performance of these dams, including competent and adequate supervision, careful inspection and control testing.
Dams, which are constructed of earth and rock materials, are generally referred to as embankment dams or fill-type dams. The history of construction of embankment dams is much older than that of concrete dams. It is evident that some earth dams were constructed about 3,000 years ago in the cradles of ancient cultures such as east countries.
Instruments are used for monitoring performance of dams, which involve measurement of settlement, seepage, deformation, total stress and pore pressures within.
Fragmented rock materials as a major structural element is called a rockfill dam (singh and varshney, 1995). High quality rockfill is ideal for high‐rise dams because it provides high shear strength and good drainage. A rockfill dam often has a vertical earth core or inclined earth core for seepage control.
