Abstract
This paper presents the study of the current dynamics of the spring flood runoff layer and the highest water discharge on the Sakhalin Island rivers. We have analyzed the changes in the amount of solid the data for the precipitation amount as reported by 13 weather stations, and the flood runoff as reported by 9 hydrological posts. We have also investigated the dynamics of other climatic parameters (the sum of the positive average daily air temperatures from the beginning of snowmelt to the end of high water, the average winter height and density of snow cover). They influenced on the spring flood runoff on the River Arkovo – Arkovo village, and were registered at the Aleksandrovsk-Sakhalinsky weather station.The analysis showed that on the territory of Sakhalin Island an increase in the amount of precipitation was detected during the cold period (November-March) at the weather stations in the northern part of the island, except for the weather station Pogibi. However, there were no significant trends in the total spring flood runoff layer on the Sakhalin rivers, except of the River Tym’, where a decrease in runoff was recorded. Thus, in Sakhalin, the increase in the amount of solid precipitation did not lead to an increase in the values of the flood runoff on its rivers.
