Published 03.03.2023 The expected volume of spring flood runoff on the lowland rivers of Kazakhstan is compiled according to hydrometeorological observations and measurements as of March 01, 2023.
According to the remote sensing (remote sensing of the earth) images of NASA satellites processed by Kazhydromet RSE, as of March 01, 2023, the area of the territory of Kazakhstan covered with snow is 72%.
Analyzing the amount of precipitation, water reserves in the snow, indicators of autumn soil moisture, the depth of soil freezing, as well as ice regimes of rivers, a preliminary assessment of flood-hazardous regions is given.
Regions with increased risks: Karaganda, Akmola, North Kazakhstan, Kostanay, Aktobe, West Kazakhstan, East Kazakhstan, Abai, Almaty regions and Zhetisu region.
With medium risks: Pavlodar, Atyrau and Ulytau regions.
With low risks: Turkestan, Zhambyl, Kyzylorda and Mangystau regions.
The volume of moisture reserves in Karaganda (with the exception of the Nura River), Ulytau, Akmola (with the exception of the Zhabai River), Aktobe, West Kazakhstan and Atyrau regions is below the average annual values by 13-44%.
In the North Kazakhstan and Kostanay regions, the average annual value is 37% and 74% higher.
Currently, the process of snow accumulation continues.
Indicators of autumn soil moisture are higher than the average annual values in the river basins of Akmola, North Kazakhstan, Kostanay, Atyrau, Aktobe and West Kazakhstan regions. Below the average annual values in the river basins of the Karaganda, Ulytau, Akmola and Aktobe regions.
The depth of soil freezing is higher than last year's indicators on average from 5 to 115 cm in Ulytau, Akmola, West Kazakhstan, Atyrau and Aktobe regions. Below last year's figures, on average, from 6 to 35 cm in the Karaganda, North Kazakhstan and Kostanay regions.
In case of high temperature background and heavy rains in February, high talo-rain floods are possible along the mountain rivers of the south, south-east and east of Kazakhstan.
According to long-term observations at weather stations in March and April, a monthly precipitation rate may fall per day, which can lead to the occurrence of dangerous natural hydrometeorological phenomena.
According to the advisory synoptic weather forecast, March 2023 is expected to be mostly warm and sedimentary in most of the country.
