Central Asia & Russia: Water deficit forecast for Turkmenistan; surplus for Volga Basin

Central Asia & Russia: Water deficit forecast for Turkmenistan; surplus for Volga Basin

In the near-term water, surpluses reaching exceptional intensity will continue to emerge in Russia’s Volga River Basin and on the Ob, Vakh, and Tom Rivers, and in Aktobe, northern Kostanay, and western Akmola Regions, Kazakhstan. Exceptional deficits will increase in Yamal, Russia. Moderate to severe deficits are expected in Turkmenistan and Uzbekistan. In the spring, Volga Basin surpluses should downgrade, though remain widespread. Surpluses will persist between the Tom and Yenisei Rivers, and along the Ob and Irtysh Rivers. Severe deficits will continue to emerge in Turkmenistan and Uzbekistan. 

Central Asia & Russia: Water surpluses in the Volga River Basin and eastern Novosibirsk Oblast

Central Asia & Russia: Water surpluses in the Volga River Basin and eastern Novosibirsk Oblast

In Russia large pockets of exceptional surplus conditions are forecast for the Volga River Basin and from the Lower Ob River to the Tom River, persisting through March 2018. Deficits will continue to emerge in much of eastern Russia through March, though they are not expected to reach exceptional severity beyond September. Moderate to severe surpluses will emerge from the Ural Mountains to the western edge of the Central Siberian Plateau from October through March. Surpluses will persist in many parts of Kazakhstan and throughout Kyrgyzstan. Moderate to severe deficits are forecast for Turkmenistan and Uzbekistan through December, diminishing thereafter. 

Central Asia & Russia: Water surpluses forecast for Kazakhstan, Kyrgyzstan

Central Asia & Russia: Water surpluses forecast for Kazakhstan, Kyrgyzstan

Widespread pockets of exceptional water surplus conditions will continue across central Russia and northern and southern Kazakhstan for much of the forecast period, moderating towards early 2018. Increased flows are expected in the Ob and Volga River basins. Recent exceptional deficits across northern Russia may retreat somewhat to the northern regions of Krasnoyarsk Krai. Moderate deficits are forecast to develop over much of Turkmenistan and Uzbekistan from June through November before moderating in early 2018.

Central Asia & Russia: Water surpluses forecast for Volga River Basin, & from Ob to Tom River

Central Asia & Russia: Water surpluses forecast for Volga River Basin, & from Ob to Tom River

Widespread exceptional water deficits in northern Russia observed in the prior three months are forecast to retreat May through July. However, drier than normal conditions will persist from the Yamal Peninsula to the Sea of Okhotsk. Exceptional surpluses are forecast in the Volga River Basin, the Irtysh, and between the Ob and the Tom Rivers. Surpluses will continue to emerge in many parts of Kazakhstan and are also forecast for eastern Uzbekistan, Kyrgyzstan, and Tajikistan. Moderate deficits are forecast for Turkmenistan and central Uzbekistan. Beyond July the forecast shows a similar geographic distribution of anomalies but with some changes in conditions.

Central Asia & Russia: Water surpluses forecast from the Irtysh to the Tom River, Russia

Central Asia & Russia: Water surpluses forecast from the Irtysh to the Tom River, Russia

Widespread and exceptional water deficits observed in Russia in the prior three months are forecast to retreat April through June. However, drier than normal conditions will persist from the White Sea to the Lena River. Surpluses are forecast from the Irtysh to the Tom River, along the Middle Ob River, and between the Volga River and the Belaya River. Surpluses will continue to emerge in the many areas of Kazakhstan as well as in Kyrgyzstan, eastern Uzbekistan, and western Tajikistan. Moderate deficits are forecast for western Uzbekistan and parts of Turkmenistan.

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.
