The Hydrology and Water Use research team members published an article in the Water journal entitled \u2018Ice Regime of the Koz\u0142owa G\u00f3ra Reservoir (Southern Poland) as an Indicator of Changes of the Thermal Conditions of Ambient Air\u2019.<\/p>\n
Measurements and observations of ice phenomena in the Koz\u0142owa G\u00f3ra reservoir have been carried out since 1964. In 1964-2015, there was a decrease in the number of days with an ice cover (by 8.6 days per decade) and a decrease in the maximum and average thickness of lake ice (by 2.0 cm and 1.2 cm per decade, respectively). The small average depth and capacity of the reservoir are reflected in the rapid freezing rate of the reservoir, and the location results in a longer time of ice cover and greater thickness and later dates of ice melting, in relation to lakes located in northern Poland.<\/p>\n
