Modern zoned-earth embankments employ filter and drain zones to collect and remove seep water and preserve the integrity of the downstream shell zone. An outdated method of zoned earth dam construction used a hydraulic fill to produce a watertight core. Rolled-earth dams may also employ a watertight facing or core in the manner of a rock-fill dam.
The zoned earth embankment creates a 204 acres (83 ha) reservoir and at normal pool stores 3,130 acre-feet (3,860,000 m 3) of water. A normal pool elevation of 1,495.3 feet (455.8 m) is maintained throughout the year via the principal and auxiliary spillways. The zoned earth fill dam is 39 feet (12 m) in height and 530 feet (160 m) long.
The average base width of the embankment is variously 1,800 m, [10] 800 m from Google Earth and 660 m. [7] So whereas one report [ 10 ] gives an embankment volume of 720×10 6 m 3 , calculations based on the width of the embankment base from these three sources give embankment volumes of 660, 290 and 240×10 6 m 3 respectively.
The remaining land served as buffer zones between development areas and the reservoir. [14] When the TVA began to approach property owners in the Lower Tennessee Valley for the development of Tellico Dam, several communities that TVA sought to "modernize" through this project were at the time in touch with most of the modern Appalachian society ...
Tailings stratification is the layering of tailings due to the distribution in particle size as well as the difference in specific density. The compactness of the sandy to silty tailings [13] influences the permeability, which will influence the drainage ability of the tailings and thus the infiltration line. [14]
The New Waddell Dam is 300 ft (91 m) high from the riverbed and 440 feet (130 m) high from its bedrock foundation. It is a zoned earth-fill type and is 4,700 ft (1,433 m) long; containing 16,200,000 cu yd (12,385,789 m 3) of material. The dam has a crest width of 35 feet (11 m) and a base width of 1,514 feet (461 m). [4]

The construction of the canal head works began in March 1948, and was completed a year later. Designed as a zoned earth embankment structure with an impervious central core, a semi-pervious layer on either side of the core, and a layer of rock fill. The semi-pervious layer was built in 1 foot (0.30 m) layers and compacted.
