ABSTRACT
Earthfill dams are a form of embankment dam of which more than half the crosssections are constructed of earth material. According to their structure, earthfill dams are divided into the following basic categories:
Homogeneous dams, which are constructed of one kind of low-permeable earth material (Fig. 10.1a);
Zoned earthfill dams, a cross-section of which is filled with different materials which are arranged in such manner so that water-permeability increases towards the downstream face (Fig. 10.1b), or the most impermeable material is placed in the central part (Fig. 10.1c).
