Earthen embankment with spillway
started by excavating soil from nearby borrow pits. Soil is spread out in 20 cm thick
uniform layers and then compacted by ramming with stone hammers to a thickness
of 10 cm. Alternatively, a sheep's-foot roller can be used for compaction. Usually a
relative compaction of 0.95 or higher should be achieved.
