Abstract

The analysis of more than a hundred of the Sakhalin rivers having the flood basins from 10 up to 6000 km² brought to light a number of features of the river channel forming. For different part of the island some causes of the channels deepness are being revealed. The six principal types of the limiting conditions found on the Sakhalin Island are distinguished. A special attention is paid to inherited alluvial form in river channels. A new point of view on determination of the channelforming discharge are being introduced. A new data about the region character of QI-diagramm have been received.
