Encyclopedia
The Engineer Souza Dias Dam, formerly known as the Jupiá Dam is an embankment dam
on the Paraná River
near Três Lagoas in São Paulo
, Brazil. It was constructed for hydroelectric power production, flood control
and navigation
. Studies on the dam and power plant began in 1951 which recommended the dam along with the Ilha Solteira Dam
. The dam was inaugurated in 1968 and its generators were commissioned between 1969 and 1974.
section section of the dam measures 1040 m (3,412.1 ft) long while the earth-fill embankments flanking the concrete section measure 2070 m (6,791.3 ft) long on the right and 2385 m (7,824.8 ft) long on the left. The reservoir
created by the dam has a 3.353 km³ (0.804427479600173 cu mi) capacity of which 900000000 cubic metre is live (active or "useful") storage. The reservoir has a catchment area of 470000 square kilometre and surface area of 330 square kilometre as well. The dam's spillway contains 37 floodgate
s, each with a 1208 m3/s discharge capacity for a total discharge of 44696 m3/s. The average long-term flow at the dam is 6350 m3/s and the record maximum flow was 28943 m3/s which was reached on October 2, 1983.
The dam's navigation lock is 210 m (689 ft) long, 17 m (55.8 ft) wide and affords transportation on the Paraná and Tietê River
s. It was inaugurated January 1998.

s for a total installed capacity of 1,551.2 MW. In addition, the power station contains two 5 MW service generators for powering the dam's facilities itself. Together, dam's generators are designed to discharge 6440 m3/s of water, bringing the total discharge capability of the dam to 50130 m3/s at a reservoir elevation of 280.5 m (920.3 ft) above sea level.
Embankment dam
An embankment dam is a massive artificial water barrier. It is typically created by the emplacement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay and/or rock. It has a semi-permanent waterproof natural covering for its surface, and a dense, waterproof...

Flood control
In communications, flood control is a feature of many communication protocols designed to prevent overwhelming of a destination receiver. Such controls can be implemented either in software or in hardware, and will often request that the message be resent after the receiver has finished...
and navigation
Navigability
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and slow enough for a vessel to pass. Preferably there are few obstructions such as rocks or trees to avoid. Bridges must have sufficient clearance. High water speed may make a channel unnavigable. Waters may be...

Dam and reservoir
The Souza Dias Dam is a 53 m (173.9 ft) high and 5495 m (18,028.2 ft) long combination concrete gravity and embankment dam. The concrete power plant, navigation lock and spillwaySpillway
A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically being the river that was dammed. In the UK they may be known as overflow channels. Spillways release floods so that the water does not overtop and damage or even destroy...

Floodgate
Floodgates are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or...
