The diaphragm which forms the water barrier may consist of <br />earth, portland cement concrete, bituminous concrete, or other material, and may <br />occupy a position within the embankment or on the upstream face. <br /> <br />Dike. - A low embankment, usually constructed to close up low areas of the <br />reservoir rim and thus limit the extent of the reservoir. <br /> <br />4 <br />
