Desna River is the largest tributary of the Dnieper River. Desna joins the larger river from the left, about 6 km before the Ukrainian capital Kiev.

The length of the Desna River is 1130 km, whereas the mean drainage basin has a size of 88, 900 square kilometers. 591 km of its length enter the territory of Ukraine.
Once departed from Smolensk Heights, Desna heads to a low wetland valley, formerly known by the name of Briansk. In this section the right bank of the river is considerably higher than the left.
A little further on, Desna River merges with Seim, and its bed significantly expands and thus cuts the number of overlapping sleeves. Desna goes low past the city of Chernihiv, divided by one of its tributaries - Oster, and remains on course to calm Ukraine.
In his Ukrainian section, Desna reaches a bed width of 60 to 250 meters and its average depth is 3 meters.
Usually it freezes from early December to early April, leaving it still navigable by Novhorod-Siverskyi, at the mouth, which has a length totaling 535 kilometers.
