При обосновании проектных решений в гидротехническом строительстве, разработке мероприятий по использованию и охране водных ресурсов практический и научный интерес представляет информация о внутригодовом распределении стока. Представлены итоги корреляционного анализа ежедневных уровней воды в реках Калининградской области по результатам наблюдений в годы разной водности с 2008 по 2021 г.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Выполнен статистический анализ массива данных наблюдений за ежедневными уровнями воды в 12 створах рек Калининградской области за период с 2008 по 2021 г. Источник данных — автоматизированная информационная система государственного мониторинга водных объектов. Обработка результатов наблюдений осуществлялась в среде Mathcad.</p></sec><sec><title>Результаты</title><p>Результаты. Рассчитаны коэффициенты парной корреляции (КПК) между ежедневными уровнями воды в исследуемых створах рек Калининградской области. Определены средние, наибольшие и наименьшие КПК ежедневных уровней воды в рассматриваемых створах. Установлена зависимость КПК ежедневных уровней воды в двух створах, расположенных в одной речной системе, и для разных речных систем.</p></sec><sec><title>Выводы</title><p>Выводы. Выявлено, что наиболее тесная стохастическая связь ежедневных уровней воды наблюдается у р. Неман и рук. Матросовка; в маловодные годы значения КПК ежедневных уровней воды в рассматриваемых створах снижаются; в качестве аналогов для водотоков Калининградской области следует рекомендовать р. Преголю (ГП Гвардейск) и р. Инструч (ГП Ульяново). Полученные результаты могут быть использованы при разработке мероприятий по использованию и охране водных ресурсов региона.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. When justifying design decisions in hydraulic engineering, developing measures for the use and protection of water resources, information on the intra-annual distribution of runoff is of practical and scientific interest. The paper presents the results of a correlation analysis of daily water levels in the rivers of the Kaliningrad region, based on the results of observations in years with different water content from 2008 to 2021.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The statistical analysis of the data set of observations of daily water levels in 12 river stations of the Kaliningrad region for the period from 2008 to 2021 was carried out. The data source was the automated information system of state monitoring of water bodies. The observation results were processed in Mathcad environment.</p></sec><sec><title>Results</title><p>Results. Pair correlation coefficients between daily water levels in the studied river stations of the Kaliningrad region were calculated. The average, maximum and minimum pair correlation coefficients of daily water levels in the considered stations were determined. The dependence of pair correlation coefficients of daily water levels in two stations located in the same river system (The Angrapa River – Berestovo gauging station – The Pregolya River – Gvardeysk gauging station) and for different river systems (The Mamonovka River – Mamonovo gauging station – The Pregolya River – Chernyakhovsk gauging station) was determined.</p></sec><sec><title>Conclusions</title><p>Conclusions. It was found that the closest stochastic relationship of daily water levels is observed near the Neman and Matrosovka Rivers; in dry years, the values of the pair correlation coefficients of daily water levels decrease in the studied stations; The Pregolya river (Gvardeysk gauging station) and the Instruch River (Ulyanovo gauging station) should be recommended as analogues for watercourses of the Kaliningrad region. The obtained results can be used for the development of measures for the use and protection of water resources in the region.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>внутригодовое распределение стока</kwd><kwd>водность реки</kwd><kwd>гидрологические расчеты</kwd><kwd>ежедневные уровни воды</kwd><kwd>Калининградская область</kwd><kwd>река Анграпа</kwd><kwd>река Инструч</kwd><kwd>река Мамоновка</kwd><kwd>река Писса</kwd><kwd>река Преголя</kwd><kwd>рукав Дейма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intra-annual distribution of runoff</kwd><kwd>river water content</kwd><kwd>hydrological calculations</kwd><kwd>daily water levels</kwd><kwd>Kaliningrad region</kwd><kwd>Angrapa river</kwd><kwd>Instruch river</kwd><kwd>Mamonovka river</kwd><kwd>Pissa river</kwd><kwd>Pregolya river</kwd><kwd>Deyma river</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда и Правительства Калининградской области в рамках научного проекта № 22-27-20016.</funding-statement><funding-statement xml:lang="en">The work was financially supported by the Russian Science Foundation and the Government of the Kaliningrad Region under the scientific project No. 22-27-20016.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Фролова Н.Л., Нестеренко Д.П., Шенберг Н.В.
