Inanda Dam
Inanda Dam is an earth-fill type dam located on the Umgeni River, near Hillcrest, KwaZulu-Natal, South Africa. It was established in 1989 and its primary purpose is to serve for domestic and industrial use.
Earth-fill dams, also called earthen dams, rolled-earth dams or simply earth dams, are constructed as a simple embankment of well compacted earth. A homogeneous rolled-earth dam is entirely constructed of one type of material but may contain a drain layer to collect seep water. A zoned-earth dam has distinct parts or zones of dissimilar material, typically a locally plentiful shell with a watertight clay core. 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 An outdated method of zoned earth dam construction utilized a hydraulic fill to produce a watertight core.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. An interesting type of temporary earth dam occasionally used in high latitudes is the frozen-core dam, in which a coolant is circulated through pipes inside the dam to maintain a watertight region of permafrost within it.
Tarbela Dam is a large dam on the Indus River in Pakistan. It is located about 50 km (31 mi) northwest of Islamabad, and a height of 485 ft (148 m) above the river bed and a reservoir size of 95 sq mi (250 km2) makes it the largest earth filled dam in the world. The principal element of the project is an embankment 9,000 feet (2,700 metres) long with a maximum height of 465 feet (142 metres). The total volume of earth and rock used for the project is approximately 200 million cubic yards (152.8 million cu. Meters) which makes it the largest man made structure in the world, except for the Great Chinese Wall which consumed somewhat more material.
Because earthen dams can be constructed from materials found on-site or nearby, they can be very cost-effective in regions where the cost of producing or bringing in concrete would be prohibitive.
You will require a high raised vehicle with minimum diff lock should you wish to park and grab this cache. All other vehicles park at parking co-ords given then a short walk down to the cache.
A camera would also be a plus as the view is spectacular if the wall is in full flow.
