На реке возводят шлюзы. 
Судоходный шлюз — гидротехническое сооружение на судоходных и водных путях для обеспечения перехода судов из одного водного бассейна (бьефа) в другой с различными уровнями воды в них. Он с двух сторон ограничен затворами, между располагается смежная камера, позволяющая варьировать уровень воды в её пределах. Перевод судов посредством судоходного шлюза осуществляется последовательным переводом в смежную камеру после выравнивания в них уровня воды. Использование шлюзов главным образом направлено на то, чтобы сделать водные пространства с различными уровнями воды в них более пригодными для судоходства.
