Portugués Dam
The Portugués Dam (Spanish: ''Represa Portugués'') is a roller-compacted concrete thick arch dam on the Portugués River, three miles (5 km) northwest of the city Ponce, in Barrio Tibes, Ponce, Puerto Rico. Construction on the dam began in April 2008, soon after the U.S. Army Corps of Engineers, Jacksonville District awarded the Spanish firm Dragados USA, a division of Grupo ACS, with a $180 million contract in March 2008 to build the dam. The primary purpose of the dam is flood control; it provides flood protection for 40,000 people and over 13,000 residential structures. The dam is the final component of the Portugués and Bucana Flood Protection Project and the first dam of its type constructed by the U.S. Army Corps of Engineers in the United States or Caribbean. The final cost of the dam was estimated at $375 million; 75% is funded by the U.S. Government and 25% by the Government of Puerto Rico.

Tibes
Tibes (''Barrio Tibes'') is one of the 31 barrios in the municipality of Ponce, Puerto Rico. Together with Magueyes, Portugués, Montes Llanos, Maragüez, Machuelo Arriba, Sabanetas, and Cerrillos, barrio Tibes is one of the municipality's eight rural interior barrios. Tibes attracted attention recently when, in 1975, what was to become the discovery of the oldest cemetery in the West Indies came about as a result of rainstorms. The name of this barrio is of native Indian origin. It was organized in 1831. Location Tibes is a mountainous rural barrio located in the central section of the municipality, north of the city of Ponce. Tibes is located on the foothills of the Cordillera Central. The toponymy, or origin of the name, is related to the hard, smooth stones plentiful in the rivers of this barrio and used by the indigenous peoples of the area as a weapon and the jíbaro countrymen for sharpening agricultural tools such as the machete.

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Petroglyph
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix , from meaning "stone", and meaning "carve", and was originally coined in French as . Another form of petroglyph, normally found in literate cultures, a rock relief or rock-cut relief is a relief sculpture carved on "living rock" such as a cliff, rather than a detached piece of stone. While these relief carvings are a category of rock art, sometimes found in conjunction with rock-cut architecture, they tend to be omitted in most works on rock art, which concentrate on engravings and paintings by prehistoric or nonliterate cultures. Some of these reliefs exploit the rock's nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taíno People
The Taíno were a historic indigenous people of the Caribbean whose culture has been continued today by Taíno descendant communities and Taíno revivalist communities. At the time of European contact in the late 15th century, they were the principal inhabitants of most of what is now Cuba, Dominican Republic, Jamaica, Haiti, Puerto Rico, the Bahamas, and the northern Lesser Antilles. The Lucayan branch of the Taíno were the first New World peoples encountered by Christopher Columbus, in the Bahama Archipelago on October 12, 1492. The Taíno spoke a dialect of the Arawakan language group. They lived in agricultural societies ruled by caciques with fixed settlements and a matrilineal system of kinship and inheritance. Taíno religion centered on the worship of zemis. Some anthropologists and historians have claimed that the Taíno were exterminated centuries ago or they gradually went extinct by blending into a shared identity with African and Spanish cultures. However, many p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batey (game)
''Batéy'' was the name given to a special plaza around which the Caribbean Taino built their settlements. It was usually a rectangular area surrounded by stones with carved symbols (petroglyphs). The ''batey'' was the area in which ''batey'' events (e.g. ceremonies, the ball game, etc.) took place. The ''batey'' ceremony (also known as ''batu'') can be viewed from some historical accounts as more of a judicial contest rather than a game. Because historical accounts of the game and court space come from (mostly Spanish) European explorers, the true nature, history, and function of the ''batey'' is still contested. Neighboring tribes may have used batey matches to resolve differences without warfare. Distribution Bateys are found in Turks, Caicos, St. Croix, Dominican Republic, The Bahamas, eastern Cuba, Haiti, and "the largest number of known ball courts are to be found in Puerto Rico and the U.S. Virgin Islands". Batey origins There is no consensus as to whether the ''batey'' ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-Columbian Era
In the history of the Americas, the pre-Columbian era spans from the Migration to the New World, original settlement of North and South America in the Upper Paleolithic period through European colonization of the Americas, European colonization, which began with Christopher Columbus's voyage of 1492. Usually, the era covers the history of Indigenous peoples of the Americas, Indigenous cultures until significant influence by Europeans. This may have occurred decades or even centuries after Columbus for certain cultures. Many pre-Columbian civilizations were marked by permanent settlements, cities, agriculture, civic and monumental architecture, major earthworks (archaeology), earthworks, and Complex society, complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European colonies (c. late 16th–early 17th centuries), and are known only through archaeology of the Americas, archaeological investigations and oral history.

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aggregate (composite)
Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel. Comparison to fiber composites ''Aggregate composites'' tend to be much easier to fabricate, and much more predictable in their finished properties, than '' fiber composites''. Fiber orientation and continuity can have an overwhelming effect, but can be difficult to control and assess. Fabrication aside, aggregate materials themselves also tend to be less expensive; the most common aggregates mentioned above are found in nature and can often be used with only minimal processing. Not all composite materials include aggregate. Aggregate particles tend to have about the same dimensions in every direction (that is, an aspect ratio of about one), so ...
