The article analyzes the interannual variability of flood runoff in the Teteriv River basin over a long period of observation. The rivers of the studied basin are characterized as flat with a pronounced spring flood. The river is of important water management importance for the Zhytomyr and Kyiv regions and is a source of drinking water for a number of settlements, including the cities of Zhytomyr and Korostyshiv. Its waters are also used for industrial needs, in particular by enterprises operating along its banks. The nature of the river’s water regime is largely determined by the characteristics of the spring flood, its duration and the percentage ratio in the annual runoff, which is determined by the type of feeding. The highest average monthly water flows are observed in March-April. The duration of the spring flood is 1.5-2 months. The volume of spring runoff of the rivers of the studied region constitutes the main part of the total runoff in most of the years considered.<\/em>
Generalizations of the studied characteristics of spring runoff are presented, which are based on data for a multi-year period up to 2020, inclusive, based on the hydrological-genetic method of analysis of runoff series.<\/em>
According to the constructed difference-integral curves of the time series of maximum spring flood water discharges in recent decades (starting from 1980), a long low-water phase is noted, and before that, a long high-water phase was noted from the beginning of observations. While for the runoff layers, we have a slightly different course of change in water content phases, where over the past 40 years we have a low-water phase from 1981-82 to 1994-95, and then a high-water phase to 2005-2006, and again a low-water phase.<\/em>
In the series of the largest water flows of the spring flood, a significant downward trend in the values of the runoff is noted in all considered series, except for the Teteriv River – Ivankiv Township. While in the series of the layers of the spring flood runoff, we have an insignificant trend in the series: the Teteriv River – Troscha, the Teteriv River – Ivankiv and the Irsha River – Volodarsk-Volynskyi; in all other series, a negative trend in the value of the runoff is noted.<\/em>
Analysis of the interannual variability of the spring flood volumes showed that on average, according to modern data, 32-44% is formed with an average flood duration of 39-60 days, and not 45-60%, as noted in many scientific works that summarized shorter observation data that did not cover the long low-water phase on the rivers of the region in recent years.<\/em><\/p>\n\n\n\n
