Analysis of snow reserves dependence on spring flood runoff (large tributaries of the upper Ob as a case study)

The study of correlations between the total runoff of rivers Charysh and Chumysh (Altai Krai) for the spring-summer period and the snow reserves was carried out based on the long-term observation data. The analysis of correlations veracity was performed. For both rivers, the correlation coefficient depended on the integration time interval; and such dependences had two peaks. The comparative analysis of the mentioned above relationships suggests that the correlation coefficient is dependant on the pairwise location of weather and gauging stations.
