Native kings protected it from the rivers by a masonry embankment several miles long, built of enormous blocks of hewn stone, and in some places 25 ft.
Where embankment was required drains about 5 yds.
Dams Any well-made earthen embankment of moderate height, and of such thickness and uniformity of construction as to ensure freedom from excessive percolation at any point, will in the course of time become almost impermeable to surface water standing against it; and when permeable rocks are covered with many feet of soil, the leakage through such soil from standing water newly placed above it generally diminishes rapidly, and in process of time often ceases entirely.
The sumach (Rhus glabra) grew luxuriantly about the house, pushing up through the embankment which I had made, and growing five or six feet the first season.
The deposit lies partly under the foreshore of the river Duddon, and a company has expended upwards of 120,000 upon a sea-wall and embankment to protect the mine from the sea.

Excavations carried on in 1891 led to the discovery of the northern portion of the western town wall, which in one section served at the same time as an embankment against floods (it was apparently more conspicuous in the time of P.

So fierce was the antagonism that the military authorities refused to permit operations of survey in the southern suburb of Tokyo, and the road had to be laid on an embankment constructed in the sea.
The Adige embankment gave an impetus to building enterprise, the banks of the river being now flanked by villas and large dwellinghouses.
An endeavour is made so to plan the works of a railway that the quantity of earth excavated in cuttings shall be equal to the quantity required for the embankments; but this is not always practicable, and it is sometimes advantageous to obtain the earth from some source close to the embankment rather than incur the expense of hauling it from a distant cutting.
