ABSTRACT
According to their locality, high-head river hydraulic schemes (H > 50 m) can be classified into two basic groups: (I) on mountain rivers, in deep and relatively narrow valleys, with a foundation and banks consisting of rock; and (II) on semi-lowland and lowland rivers, rich in water, with a foundation also consisting of rock. The following structures belong to the group of high-head river hydraulic schemes: high dams, spillway structures, structures for protection of the construction pit and conveyance and diversion of construction waters, powerhouse with an intake for a hydroelectric power plant and a tail race, and intakes for irrigation and water supply. Ship navigation lifts and more rarely, ship navigation locks, can also be considered as high-pressure head river hydraulic schemes of the second type.
