Dahla Dam

The Dahla Dam is the largest dam in Kandahar Province, and the second largest in Afghanistan. It was built in 1952. Over the years during the wars due to neglect the project was subject to siltation of the reservoir, the canal system and other appurtenant works which reduced its irrigation benefits. This necessitated undertaking rehabilitation of the project which was envisaged in two phases with the first phase involving desiltation works and pertinent components of the project to improve the water delivery system; this component was completed during March 2012 with full assistance provided by the Government of Canada. The second phase involves raising the height of the dam and the relevant dykes to compensate for the loss of storage in the dam due to siltation, and to achieve the full benefits of irrigation for which the dam was originally built. This component is now under implementation with financial and technical support from the US government

Location

The dam is 34 kilometres (21 mi) north of the Kandahar City in the Kandhar Province. It is built on the Arghandab River which flows over a length of 250 miles (400 km).

Dam

A dam is a barrier that impounds water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for such activities as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.

The word dam can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities.

History

Ancient dams

Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level, for Mesopotamia's weather affected the Tigris and Euphrates rivers, and could be quite unpredictable.

The earliest known dam is the Jawa Dam in Jordan, 100 kilometres (62 mi) northeast of the capital Amman. This gravity dam featured an originally 9-metre-high (30 ft) and 1 m-wide (3.3 ft) stone wall, supported by a 50 m-wide (160 ft) earth rampart. The structure is dated to 3000 BC.
