Don River
The Don River at Rostov-na-Donu, Russia.
The upper course of the Don River exhibits distinct geological differences between its banks due to the river's flow along the eastern edge of the Central Russian Upland.1
- Right Bank: This side is pronounced and elevated, reaching heights of up to 160 feet above the river. Its composition of limestone and chalk is notably carved by numerous ravines and gullies, creating an undulating landscape.1
- Left Bank: In contrast, the left bank borders a flatter floodplain, characterized by the smoother, pond-dotted topography of the Oka-Don Lowland.1
These physical variations reflect the transition between the rugged terrain of the upland region and the lower-lying plains that define the river's basin.1
