The area reduced for more than 7 times. The water level decreased to 29 meters. Coastline receded in hundreds kilometers. In the western parts salinity level reached 130 gramsliter, in the eastern parts - 300 gramsliter. The dried part of Aral Sea turned into a salty desert with more than 5.0 mln hectares territory. Dust and salt storms pollute hundreds kilometers. Aralkum - the new desert 2013-2015 Uzbekistan's chairmanship in International Foundation of Aral sea Salvation. Given this background, it is worrying that countries located in the rivers' upstream are using transboundary waters in manner that contradicts internationally accepted norms and principles. They are Rogun HPS in Tajikistan and Kambarata HPSs in Kyrgyzstan. ROGUN HYDROELECTRIC POWER STATION PROJECT dam height of 335 meters tectonic break under the Rogun HPS filled by rock salt with the depth of 100 meters natural catastrophes occur periodically in the area with the magnitude of 9 or more by the Richter's scale In the case of Rogun HPS's dam break: - wave height at the starting point: 200 meters; - wave velocity in the first 4-5 km: 40-129 ms; at the end point (the Republic of Karakalpakstan, more than 1400 km away from the Rogun HPS) wave will reach a height of 6-7 meters; the whole cascade of downstream HPSs will be destroyed (Nurek HPS, Vakhsh cascade №1, №2, Perepadnaya HPS №1, №2, Sangtuda HPS №1 and №2); the area of 1.3-1.5 million hectares, more than 700 settlements in the territory of Tajikistan, Afghanistan, Uzbekistan and Turkmenistan inhabited by about 6.7 million people will be flooded. It would take 8 years to fill the Rogun HPS's reservoir up to its project capacity of 13.3 cu. km. These issues were discussed in detail at a meeting of the Ecomovement with responsible officials of the World Bank, prominent non-governmental organizations in United States, other international organizations, who noted that concerns of Uzbekistan about Rogun HPS project are reasonable and fair.
