How do navigable locks help ships travel along the Dnieper River?

On the Dnieper River, navigable locks are essential for enabling the passage of modern vessels, particularly below the confluence with the Pripet River where the river has been canalized.1

These locks function as enclosures or basins with gates at each end, allowing ships to navigate the different water levels created by hydroelectric dams and other impounding barriers along the river. The process works as follows:23

• Raising vessels: When a ship needs to move to a higher water level, it enters the lock chamber. The downstream gates are closed, and the chamber is filled with water until it matches the level of the upper pound. Once equalized, the upstream gates are opened to allow the vessel to exit.23
• Lowering vessels: To move to a lower level, the ship enters the chamber from the higher side. After the upstream gates are closed, water is drawn out of the chamber until the level matches the lower pound, at which point the downstream gates are opened for the vessel to proceed.23

By managing these water levels, locks create a continuous deepwater route for navigation.1
