Transformation of sand formations in deltas of major tributaries due to lake Baikal level fluctuations

In the work, it is studied the state dynamics of sand formations, connected with Lake Baikal level increase, in deltas of the main tributaries. It is observed a significant decrease in the length and area of islands, peninsulas, and sand bars in the lacustrine parts of deltas. In some places, the islands configuration has changed, and braid bars have formed.
