  • The impact of climatic change on water quality in cold, snowy region was examined at the Barato river a stagnated waters. The freezing period of river has been shortening, a finding based on the analysis of weather and water quality data from 1998 to 2008.Moreover, changes have been observed in the water quality variation of water under the river ice, and climatic change has been shown to influence the water quality during the thawing season. An ecosystem model that incorporates freezing was constructed, and the impact of global warming on Barato river was simulated. The model was able to reproduce water quality variation in the freezing period. In the simulation, an atmospheric temperature increase of 6.4 degree centigrade produced an average BOD increase of 3% to 12%.The rate of increase was high at the highly stagnated waters, and the rise in BOD concentration during the thawing season was remarkable.
