The rapids and barriers
 

The rapids and barriers made continuous navigation on the Dnieper River impossible. They divided the navigable river into two sections: one above and the other below the rapids. Hence, in the 18th century when the whole Dnieper came under Russian control, attempts were begun to regulate the Dnieper at the stretch of rapids. The first projects in 1785 by Col N. Faleev and in 1795–1807 by de Bolan did not achieve any important results. In 1843–54 canals were constructed on the left bank around all the rapids, and the most dangerous cliffs in the barriers were removed.
