Abstract
The design of hydraulic gates for barrages, river control and low-leve l outlets for reservoirs is discussed with reference to three differen t projects. These are the hood prevention scheme for the city of Venic e, the Torrumbarry Weir for the control of the Murray River in Austral ia and the bottom outlet for the Karapiro Dam in New Zealand. Large ba rrages often require special solutions for the design of gates and ope rating machinery; the Venice barrages are an example. River control st ructures and gates for hydropower plants are usually controlled by ele ctromechanical or oil-hydraulic machinery. The schemes are typical of present practice. The projects are briefly described and features of t heir operating machinery are discussed, as well as their effect on the safety and reliability of the gate installation.
