Spring flooding is an annual significant overflow of water in the central Russia rivers. As a rule, the maximum flood levels in the Tambov region rivers are reached in the late March - early April. However, this parameter is very variable. Moreover, the maximum flood water level varies from year to year. In this paper, we study the effects of various climatic parameters on the spring flood peak formation. We consider the Tsna River (the Oka basin) near Tambov as the model object of our study. Using methods of multiple correlation analysis, we determine the most significant climatic factors which affect the maximum flood level. In the research, 16 climatic and hydrological parameters from 1970 to 2018 are analyzed. We assess the contribution of the various factors to flood wave formation by using multiple regression analysis. Using the analysis, we have identified the most significant flooding factors.

В статье представлены данные о ресурсах поверхностного стока в бассейне реки Воронеж в пределах территории Тамбовской области. Приведены карты модулей стока за летние месяцы, дана оценка объёма стока с изученной территории за каждый из летних месяцев. In this paper the data on surface runoff resources in the Voronezh River basin within the territory of the Tambov region are shown. The maps of runoff modules for the summer months are presented, and an estimate of the runoff volume from the studied territory for each of the summer months is given.
