Paulo Afonso Falls
Paulo Afonso Falls ( Portuguese: Cachoeira de Paulo Afonso) is a series of waterfalls on the São Francisco River in the north-east of Brazil adjacent to the city of Paulo Afonso. Structure The falls consist of a series of tiered cascades that descend approximately before plunging into a narrow gorge. The falls have an overall height of . Prior to damming, the falls had an estimated flow rate of and a maximum flow rate of at least . This would have made the falls the largest in Brazil and among the largest in the world. History The waterfall has been known to the indigenous population of the São Francisco River basin since time immemorial and to Portuguese colonizers since the 16th century. Damming In 1912, the São Francisco River was dammed by the Hidrelétrica de Angiquinho upstream of the falls. The hydroelectric dam the first hydroelectric power station in northeastern Brazil. In the early 1940s, the Brazilian government sponsored the expansion of the Hidrelétric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paulo Afonso Hydroelectric Complex
The Paulo Afonso Hydroelectric Complex (Complexo Hidrelétrico de Paulo Afonso), also known as the Paulo Afonso Complex, is a system of three dams and five hydroelectric power plants on the São Francisco River near the city of Paulo Afonso in Bahia, Brazil. The complex exploits an natural gap on the river, known as the Paulo Afonso Falls. Constructed in succession between 1948 and 1979, the dams support the Paulo Afonso I, II, III, IV and Apollonius Sales (Moxotó) power plants which contain a total of 23 generators with an installed capacity of . PA I was the first large power plant constructed in Brazil and the complex constitutes the densest area of dams in Brazil. The complex provides electricity to areas in northeastern Brazil and is the main tourist attraction in the region. Background and history On January 23, 1913, the 1.1 MW Angiquinho Hydroelectric Plant, built by industrialist Delmiro Gouveia, was the first use of the Paulo Afonso Falls for power production and ...

Waterfall
A waterfall is any point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling onto softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls since prehistory, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century, they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Gorge
A canyon (; archaic British English spelling: ''cañon''), gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Exa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volumetric Flow Rate
In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol (sometimes \dot V). Its SI unit is cubic metres per second (m3/s). It contrasts with '' mass flow rate'', which is the other main type of fluid flow rate. In most contexts a mention of "rate of fluid flow" is likely to refer to the volumetric rate. In hydrometry, the volumetric flow rate is known as '' discharge''. The volumetric flow rate across a unit area is called '' volumetric flux'', as defined by Darcy's law and represented by the symbol . Conversely, the integration of a volumetric flux over a given area gives the volumetric flow rate. Units The SI unit is cubic metres per second (m3/s). Another unit used is standard cubic centimetres per minute (SCCM). In US customary units and imperial units, volumetric flow rate is often expressed as ...

Colonial Brazil
Colonial Brazil (), sometimes referred to as Portuguese America, comprises the period from 1500, with the Discovery of Brazil, arrival of the Portuguese, until 1815, when Brazil was elevated to a United Kingdom of Portugal, Brazil and the Algarves, kingdom in union with Portugal. During the 300 years of Brazilian colonial history, the main economic activities of the territory were based first on Paubrasilia, brazilwood extraction (brazilwood cycle), which gave the territory its name; sugar production (Brazilian sugar cycle, sugar cycle); and finally on gold and diamond mining (Brazilian Gold Rush, gold cycle). Slaves, especially those Atlantic slave trade to Brazil, brought from Africa, provided most of the workforce of the Brazilian export economy after a brief initial period of Indigenous slavery to cut brazilwood. In contrast to the neighboring Spanish America, Spanish possessions, which had several Viceroy, viceroyalties with jurisdiction initially over New Spain (Mexico) and V ...
