We estimated the water budget of a Ramsar site, La Tembladera wetland, for a two-year period (2018-2019) by using the water balance method. The evapotranspiration was calculated using the Thornthwaite method and the runoff was estimated using the Curve Number method. The proposed water balance model showed that the major inflows to the wetland were the San Agustín and Bellavista canals, and Estero Pinto, about 92.9% (2018) and 90.5% (2019) of the total inflows. The runoff and wastewater flows represented the minor inflows. The runoff was 0.003% in 2018 and 0.004% in 2019, whereas the wastewater volume accounted for 0.05% of all inflows in both years. The actual evapotranspiration was the major outflow in both years, being 67.1% (2018) and 73.6% (2019) of the total outflows. On the other hand, the irrigation canal was the minor outflow, 32.9% in 2018 and 26.4% in 2019. Therefore, La Tembladera wetland hydrology is mostly linked to the canals system and climate conditions, precipitation and actual evapotranspiration. Our findings could be the basis for further research and developing plans in order to rationally manage and protect this wetland of international importance.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Водно-болотные угодья подвергаются деградации и исчезновению в результате антропогенного воздействия, такого как загрязнение бытовыми и промышленными сточными водами, загрязнение сельскохозяйственными стоками, преобразование земель и т. д. Оценка и прогноз гидрологических процессов водно-болотных угодий, а именно притоков и оттоков, необходимы для разработки и внедрения проектов, направленных на управление и охрану водно-болотных угодий. Был проведен расчет водного баланса водно-болотного угодья La Tembladera за двухлетный период (2018 и 2019 гг.) с использованием метода водного баланса. Эвапотранспирация была оценена по методу Thornthwaite, а ливневые стоки по методике «Число кривых стока». Предложенная модель водного баланса показала, что основные притоки в водно-болотное угодье приходятся на каналы San Agustín и Bellavista, а также на Estero Pinto, около 92,9 % (2018 г.) и 90,5 % (2019 г.) от общего объема притоков. Наименьшими притоками являлись ливневой сток и сточные воды. Ливневые стоки составили 0,003 % в 2018 г. и 0,004 % в 2019 г. Объем сточных вод составил 0,05 % от всех притоков в оба года. Выявлено, что фактическая эвапотранспирация является основным оттоком, составляя 67,1 % (2018 г.) и 73,6 % (2019 г.) от общего объема оттоков. Вместе с тем наименьший отток принадлежит каналу для орошения, он составил 32,9 % в 2018 г. и 26,4 % в 2019 г. Таким образом, гидрология водно-болотного угодья La Tembladera в основном связана с системой каналов и климатическими условиями, осадками и фактической эвапотранспирацией. Полученные результаты могут стать основой для дальнейших исследований и разработки проектов по рациональному природопользованию и охране данного объекта международного значения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>water balance</kwd><kwd>wetland hydrology</kwd><kwd>wetland management</kwd><kwd>tropical wetland</kwd><kwd>La Tembladera</kwd><kwd>La Tembladera</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>водный баланс</kwd><kwd>гидрология водно-болотных угодий</kwd><kwd>управление водно-болотными угодьями</kwd><kwd>тропическое водно-болотное угодье</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mitsch WJ, Bernal B, Hernandez ME.
