Abstract :
A general outline of the status of modern hydroelectric developments is presented in this report by an A.I.E.E. subcommittee.∗ Major topics discussed are: developed water power of the world, present trends in utilization of water power, and hydraulic and hydrodynamic research. It is hoped that this report not only will present a retrospective picture of results achieved, but also will serve as a source from which general information can be obtained and conclusions drawn concerning modern trends of hydroelectric developments.
