Одним из методов изучения динамики подземных вод при невозможности проведения систематических круглогодичных наблюдений является численное моделирование. Цель выполненных исследований – создать математическую модель фильтрации надмерзлотно-межмерзлотных подземных вод, широко распространенных на правобережье р. Лена в Центральной Якутии, и оценить межгодовую изменчивость их ресурсов. Трехмерная стандартная геофильтрационная модель была создана в программе MODFLOW-USG. Исходными данными для ее построения послужили результаты многолетних полевых гидрогеологических и геокриологических исследований, полученные на водосборной площади одного из круглогодично действующих наледеобразующих источников на бестяхской террасе р. Лена. Для калибровки численной модели использованы данные натурных наблюдений за уровнем воды в скважине, расположенной в зоне транзита межмерзлотных вод. Корректировка фильтрационных параметров и граничных условий модели проводилась до тех пор, пока расхождение между расчетными и фактическими значениями уровня межмерзлотных вод не составило менее 0,1 м для более чем 90 % измерений. Результаты моделирования позволили оценить динамику водообильности межмерзлотного водоносного талика за последние 15 лет, уточнить влияние различных метеорологических факторов и процессов сезонного промерзания-протаивания пород на формирование режима подземных вод, количественно оценить внутригодовую изменчивость дебита источника. Полученные результаты могут послужить основой для постановки задач по прогнозированию изменения мерзлотно-гидрогеологических условий под действием колебаний климата, а также рассматриваться как эффективный метод количественной оценки динамики подземных вод в области распространения многолетнемерзлых пород.</p></abstract><trans-abstract xml:lang="en"><p>In permafrost regions, the combined effects of climate change and increased anthropogenic activity highlight the need to study the formation processes and dynamics of supraand intrapermafrost waters, due to their strong responsiveness to external influences. When continuous year-round observations are not possible, numerical modeling provides an efficient approach to study groundwater dynamics. This study aims to construct a mathematical model of suprapermafrost and intrapermafrost groundwater flow prevalent along the right bank of the Lena River in Central Yakutia, and to evaluate the interannual variability of these groundwater resources. A three-dimensional groundwater flow model was developed using the MODFLOW-USG software. This model was constructed using baseline data obtained from extensive, long-term field investigations in hydrogeology and geocryology conducted within the catchment area of a perennial icing spring located on the Bestyakh Terrace of the Lena River. The numerical model was calibrated using field-observed water levels from a monitoring well located within the intrapermafrost water transit zone. Calibration involved iterative adjustments of hydraulic parameters and boundary conditions until the deviation between simulated and observed intrapermafrost water levels was less than 0.1 m for more than 90% of the measurements. The simulation results enabled the reconstruction of the water yield dynamics in the intrapermafrost aquifer talik over the past 15 years, clarified the effects of various meteorological factors and seasonal freeze-thaw cycles on groundwater regime formation, and provided a quantitative evaluation of spring discharge variability at intra-annual scales. These findings establish a foundation for developing predictive frameworks of permafrost-hydrogeological evolution in response to climatic variability and provide a robust methodological approach for quantifying groundwater dynamics in permafrost-affected regions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>надмерзлотно-межмерзлотный талик</kwd><kwd>подземные воды</kwd><kwd>моделирование</kwd><kwd>MODFLOW-USG</kwd><kwd>фильтрационные свойства</kwd><kwd>уровень воды</kwd><kwd>дебит источника</kwd></kwd-group><kwd-group xml:lang="en"><kwd>suprapermafrost–intrapermafrost talik</kwd><kwd>groundwater</kwd><kwd>modeling</kwd><kwd>MODFLOW-USG</kwd><kwd>filtration properties</kwd><kwd>water level</kwd><kwd>spring discharge</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Программы фундаментальных научных исследований ИМЗ СО РАН «Подземные воды криолитозоны: закономерности формирования и режима, особенности взаимодействия с поверхностными водами  и  мерзлыми  породами,  перспективы  использования» (№ 122012400106-7).</funding-statement><funding-statement xml:lang="en">This study was conducted with the support of the Scientific Research Program at the Melnikov Permafrost Institute of SB RAS “Groundwater in permafrost: Formation and regime patterns, interaction with surface water and frozen rocks, and prospects for use” (No. 122012400106-7).</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">Пигузова В.М., Шепелев В.В.
