The design flow rate, the dimensions of transmission structure and penstock size have a large impact on cost run-of-river type hydroelectric power plants. Equipment costs constitute part total budget plant. Optimum sizing, which maximizes use hydraulic potential, does not fit together with optimum is necessary to obtain economic benefit from its investment. main parameters can be selected help ...

The problem of load distribution between hydraulic units at hydropower plants is a difficult task due to the nonlinearity hydro turbine characteristics and individual peculiarities generation units, in which operating conditions are often different. It necessary apply most up-to-date optimization methods that take into account characteristics. must also consider strict constraints on operation ...

Landslide stability analysis is the basement of landslide research. To study influence water on reservoir stability, taking a for example in hydroelectric power station based detailed field investigation and operation data, geological conditions, rainfall were considered, slope failure pattern under natural state rain simulated with Mohr-Coulomb criterion after an numerical three-dimensional mo...

The paper relates how some key IT applications were developed in Iceland following the introduction of the first computers in 1964. The key applications treated are the National Register of Persons, real estate assessment, financial systems, centralised processing of bank checks, fish stock abundance computations, IT in fish processing plants, the control of hydroelectric power stations, and th...

Eight known species of Demidospermus (Dactylogyridae, Monogenea) were collected from siluriform fishes from reservoir of the Itaipu Hydroelectric Power Station, Paraná, Brazil. Four of them are recorded for the first time in Brazil, enlarging their geographical distribution: Demidospermus armostus, Demidospermus anus, Demidospermus bidiverticulatum and Demidospermus valenciennesi. Demidospermus...
