Central Asia: Water surpluses forecast in Kazakhstan, deficits in Turkmenistan

Central Asia: Water surpluses forecast in Kazakhstan, deficits in Turkmenistan

Water surpluses are forecast to persist along rivers in Kazakhstan through March, though a transition to both deficits and surpluses is forecast January through March as abnormal to moderate deficits begin to emerge across the country. Moderate to severe deficits in Turkmenistan and parts of Uzbekistan are expected to persist through September, diminish in October, after which moderate deficits will re-emerge throughout both countries in November. A vast expanse of moderate to exceptional water deficits are forecast through September across northern Russia from the White Sea through much of the Central Siberian Plateau. Surpluses are forecast in the Ob River Basin during this period which are expected to be especially widespread and severe in October. 

Central Asia & Russia: Water surpluses in Kazakhstan, deficits in Turkmenistan, Uzbekistan

Central Asia & Russia: Water surpluses in Kazakhstan, deficits in Turkmenistan, Uzbekistan

Exceptional water surpluses are forecast to persist through November or longer in north central Kazakhstan; northeast of the Caspian Sea; along rivers elsewhere in Kazakhstan; and the Volga River Basin in Russia. Surpluses of varying severity are also forecast for northern Kyrgyzstan. Deficits in Turkmenistan and Uzbekistan are expected to persist but with diminished severity after August. Moderate to severe water deficits are forecast to emerge in Kazakhstan from September through February.

Central Asia & Russia: Water surpluses in northern Kazakhstan, deficits in Turmenistan, Uzbekistan

Central Asia & Russia: Water surpluses in northern Kazakhstan, deficits in Turmenistan, Uzbekistan

Exceptional water surpluses are forecast in north central Kazakhstan; farther west between the Ural and Emba Rivers northeast of the Caspian Sea; and, along rivers elsewhere in Kazakhstan. Exceptional surpluses are also forecast in Russia in an area northwest of Kazakhstan, from the Volga River through the Ural Mountains. Water deficits are expected in Turkmenistan, Uzbekistan, western Kyrgyzstan and Tajikistan.

Central Asia & Russia: Water surpluses forecast in central Kazakhstan, deficits in Turkmenistan, Uzbekistan, Tajikistan

Exceptional water surpluses are forecast in north central Kazakhstan and in central Russia from the Volga River through the Ural Mountains to the western edge of the Central Siberian Plateau. Water deficits are expected in Turkmenistan, Uzbekistan, western Kyrgyzstan and Tajikistan.

Central Asia & Russia: Water surpluses forecast in Kazakhstan and Central Russia, deficits in Turkmenistan, Uzbekistan, Tajikistan

Exceptional water surpluses are forecast along rivers in Kazakhstan and central Russia from the Volga River through the Ural Mountains to the western edge of the Central Siberian Plateau. Water deficits are expected in Turkmenistan, Uzbekistan, and Tajikistan through November, with greatest severity in March.

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
