description Publicationkeyboard_double_arrow_right Part of book or chapter of book 2018Publisher:ВНИИ агрохимии Ukraine in terms of water availability ranked 17th among 20 European countries. Its water resources depend on the river flow from the territories of the neighboring countries (76.6%) and only about a fourth of it is formed within the country (23.4%). The prevailing part of the territory of the country is characterized by low and very low water availability (1.98 - 0.12 thousand m3 per person). Only the Transcarpathian region belongs to the category of average water availability (6.3 thousand m3 per person.) Most of the research results confirm the high probability of a 25-70% decrease in the water resources of the Ukraine in the 21st century. Stabilization and even an increase in water resources are expected within the Ukrainian Carpathians. Given the results of modeling, we should expect further increase in the water deficit in the zone of unsustainable agriculture - in the southern regions of Ukraine already to the middle XXI century. Украина по показателю обеспеченности водными ресурсами занимает 17 место среди 20 европейских стран. Ее водные ресурсы зависят от речного стока с территорий прилегающих стран (76,6%) и только приблизительно их четвертая часть формируется в пределах страны (23,4%). Преобладающая часть территории страны характеризуется низкой и очень низкой водообеспеченностью (1,98 - 0,12 тыс.м3 на одного человека). Лишь Закарпатская область принадлежит к категории средней обеспеченности местным стоком (6,3 тыс.м3 на одного человека. Большинство результатов исследований подтверждают высокую вероятность уменьшения водных ресурсов равнинной Украины в ХХІ веке на 25-70%. В пределах Украинских Карпат ожидается стабилизация и даже увеличение водных ресурсов. Учитывая имеющиеся результаты моделирования, следует ожидать дальнейшего увеличения дефицита водных ресурсов в зоне неустойчивого земледелия – в южных регионах Украины уже к средине ХХІ века.

To this end, we applied an approach based on hydrological modeling. In order to increase the robustness of the results, the model was calibrated in a multi-objective way using daily runoff data, long-term runoff trends, and glacier mass balance data. The results show that the runoff increase over the last 50 years is to a large extent due to an increase in air temperature and an associated increase in glacier melt. Simulations with climate scenarios indicate a further temperature-induced increase of glacier melt in the beginning of the 21st century, but then glacier melt declines due to decreasing glacier areas. Decreasing glacier melt and increasing evapotranspiration result, despite projected increases in precipitation, in decreases of total discharge in 2070-2099 compared to 1971-2000. Целью данного исследования является анализ наблюдаемых изменений стока в двух горно-ледниковых бассейнов р. Тарима на северо-западе Китая за последние 50 лет, а также оценка возможных будущих изменений ледников и водного баланса, вызванные изменением климата. Для этой цели использовалась гидрологическая модель. Чтобы повысить надежность результатов, модель была откалибрована многоцелевым методом на основе ежедневных данных расходов воды, долгосрочных трендах и балансе массы ледников. Результаты показывают, что увеличение расходов за последние 50 лет во многом связано с увеличением температуры и связынным с этим усилением таяния ледников. Моделирование по климатическим сценариям показывает сперва дальнейшее увеличение талого стока связанного с повышением температуры в XXI веке, однако в дальнейшем с уменьшением ледниковой массы, результаты указывают на значительное снижение ледникового стока. Вместе с увеличением испарения это приводит к уменьшению общего расхода в 2070-2099 гг. по сравнению с 1971-2000 гг.
