The values of winter water flow were calculated for 12 measuring posts on rivers that have a number of observations of 50 years or more and flow into Lake Sevan. The dependencies of the winter river flow on the river slope from the most distant point and the area of their catchment areas have been identified. It has been established that the main factors influencing the increase in winter river flow in recent decades are an increase in average daily air temperature, as well as an increase in the number of winter thaws. It was found that at all hydrometric points there is a decrease in the number of days with ice phenomena. At the same time, a close connection between winter runoff and days with ice phenomena could not be established. We plan to conduct more detailed studies on this in our future work 2025-10-07T01:46:49Z 2025-10-07T01:46:49Z 2025-08-25 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion peer-reviewed http://hdl.handle.net/10256/27480 info:eu-repo/semantics/altIdentifier/doi/10.46991/PYSUC.2025.59.2.386 info:eu-repo/semantics/altIdentifier/issn/1829-1759 info:eu-repo/semantics/altIdentifier/eissn/2953-7991 Reconeixement-NoComercial 4.0 Internacional http://creativecommons.org/licenses/by-nc/4.0 info:eu-repo/semantics/openAccess Yerevan State University Proceedings of the YSU.
