The Baysh Dam ( Arabic سد وادي بيش, DMG Sadd Wādī Baiš ) is located in Wadi Baisch in the Jazan Province , Saudi Arabia . It is the highest dam in Saudi Arabia. The town of Baisch is located about 33 km southeast of the dam.
The Turkish construction company Yüksel was commissioned with the construction of the dam; the contract for this was signed on April 14, 2003. The construction was completed on May 17, 2009. In addition to flood protection, the dam is also used for irrigation and filling up a groundwater reservoir. It is owned by the Ministry of Water and Electricity (MOWE) and is also operated by MOWE.
Barrier structure
The barrier structure is a concrete gravity dam with a height of 106 (or 120) m above the foundation level (74 m above the river bed). The length of the building crown is 340 m. The dam wall is 79.5 m wide at the base. The volume of the dam is 675,000 m³. The foundation is at a height of 233 m above sea level .
There are inspection corridors in the dam which are used for monitoring purposes (e.g. with regard to horizontal or vertical movement of the dam). The dam wall has both a bottom outlet and a flood relief . A maximum of 8,186 m³ / s can be discharged via the flood relief.
Reservoir
When the reservoir is full, it extends over an area of around 8.09 km² and holds 193 million m³ of water. The catchment area of the wadi up to the dam is 4,843 km². The mean annual inflow into the wadi is 74 million m³.
Others
The total cost of the project was SAR 198 million .
In 2010 the dam held back more than 200 million m³, of which 50 million m³ were used for irrigation purposes. The 200 million m³ correspond to five times the annual production of the Shuqaiq desalination plant. 200,000 m³ of water are taken from the reservoir every day; the costs of a desalination plant with a comparable annual capacity are 300 million SAR per year. This means that the cost of the dam is already paid for after eight months.
The total water consumption in Saudi Arabia in 2009 was estimated at 18.51 billion m³, the majority of which is covered by groundwater. Around 1.4 billion m³ are held back annually by a total of 302 dams.
