RIVER RUNOFF COMPONENTS AND THEIR DYNAMICS IN DIFFERENT-TYPE TRIBUTARIES OF THE UPPER OB
The yearround observation data on suspended and dissolved substances, total mineralization, concentrations of biogenic elements (N, P, C, Si) and chlorophyll a of phytoplankton as well as water discharges in mouth sections of the Upper Ob tributaries (Anui, Charysh, Alei, Talaya, Barnaulka, Losikha, Chumysh) were obtained due to monthly field studies and sampling. Seasonal dynamics of daily runoff of each component and its features in different rivers were revealed. A comparative analysis of annual volumes of water runoff, suspended solids, chemical and biotic components was performed. The relationships between annual values of runoff components with each other and with physical-geographical characteristics of the rivers were established.
