 Guri Dam - Wikipedia, the free encyclopedia
The Guri Dam is one of the largest in the world.
It is located in Bolívar State, Venezuela in the Caroni River.
It has long been the focus of much controversy, as the lake created by the dam forever destroyed thousands of square miles of forest formerly renowned for its biodiversity and rare wildlife.

 dam. The Columbia Encyclopedia, Sixth Edition. 2001-05
Single-arch dams are curved upstream and are usually constructed in narrow canyons or gorges where the rocky side walls are strong enough to withstand the tremendous lateral thrust of the dam that is caused by the pressure of the water.
Dams may also be constructed with roller-compacted concrete, in which thin layers of concrete are compacted as if they were earth layers; this produces a far stronger dam, without the need for full forms.
The Oroville Dam, located in California, the tallest in the United States, is 770 ft (235 m) high; the Rogun Dam, in Russia, the tallest in the world, is 1,100 ft (335 m) high.

 Guri dam - Venezuelatuya
Guri dam, generator of electricity for an important portion of Venezuela, was inaugurated in 1968 after long years of construction.
In that same year, sometime before the inauguration, as water level began to rise, a rescue operation of animals living in the islands and coasts of the lake being formed was carried out.
The impact of the dam was important and exemplary.

 MONITORING GURI SPILLWAY PLUNGE POOL
In this paper, an analysis based on a number of bathymetric soundings that were carried out to measure the erosion process that has ocurred in the receiving pool is presented together with estimates of energy dissipated during the period of operation in order to evaluate stabilization of the pool.
This is attributed to the effect of the pool depth in arresting the erosion capability of the flow.

Twice as high as Niagara Falls and nearly a mile long, the dam is one of the world's greatest producers of electricity, generating an incredible 22,000 megawatts of energy annually for cities in several states.
Temporary coffer dams were constructed to shift the river while excavation of the riverbed took place, and the first concrete was poured in 1935.
A highlight of the dam tour is riding the glass incline elevator to the face of the power plant for a spectacular view of the spillway from an outside balcony.

 Guri Lake Peacock Bass Fishing
Guri Lake is one of the largest man made lakes in the world stretching approximately 175 km's long and 48 kms wide.
Guri was made by the damming of the Caroni River at the confluence of the great Orinoco River — this is known as the second largest hydro electric dam called the Raul Leoni Dam.
While flooding the area for the lake, much of the timber was left and still stand upright just under the surface and poking out of the water closer to the shoreline and hilltops coming up from the lake.

 International Water Power and Dam Construction
Built over a 23-year period, Guri was completed in 1986 after utilising a unique construction concept — development of the project was phased to minimise initial investment and to match power supply to the growth in electrical system demand.
Reflecting on why the Contra dam should be considered a feat of construction, Lombardi again spoke of its aesthetic and clean design and the way that the elements of the power plant, ancillary works and dam are integrated in an ‘organic fashion’.
There are standard techniques and designs in dam building which are pretty much well known.’ When designing Ertan the concept of a double curvature arch dam was a relatively recent development in the geometry of a dam.

Although there are no plans in the works, the possibilities hanging over the Caura's fate, say observers, include the construction of a hydroelectric dam, or diverting its waters to the Caroni River, where sits the Guri dam -- the third largest hydroelectric dam in the world.
But the plans of Edelca and the state are concentrated on the Caroni," where the Guri dam has a generating capacity of 10,000 megawatts per hour.
Two other dams on the Caroni, the Carauchi and the Tocoma, produce 1,800 megawatts per hour, and a third is under construction and is to have a capacity of another 2,000 megawatts.

When the construction of a hydroelectric dam on Venezuela's Caroni River was finally completed in 1986, it flooded an area twice the size of Rhode Island, creating one of South America's largest human-made lakes: Lake Guri.
The Lake Guri story is recounted in a National Geographic four-part TV series, Strange Days on Planet Earth, which airs this Wednesday on PBS.
When the dam's second phase was finished in 1986, the water level rose steadily over a year by another 164 feet (50 meters), and about a thousand hilltops became islands in a human-made lake.

On Tuesday, the water level in the dam stood at 249 meters above sea level, Da Silva said, noting that the 248 meters level represents a state of emergency.
She added that the dam is losing about 17 centimeters a day, but the daily loss could increase given the cone-shaped nature of dams.
Given its perilously low water level, "rationing is necessary to avoid a collapse of the Guri dam," Da Silva said.

Crossing large areas of forest, including the Canaima and Gran Sabana National Parks where indigenous groups live, the power-line project has already opened gaps that logging companies are exploiting.
On August 28, meanwhile, Congress ratified Convention 169 of the International Labor Organization on Indigenous and Tribal Peoples, which guarantees the participation of indigenous communities in decision-making on issues that affect them.

Although there are no plans in the works, the possibilities hanging over the Caura's fate, say observers, include the construction of a hydroelectric dam, or diverting its waters to the Caroni River, where sits the Guri dam -- the third largest hydroelectric installation in the world.

Saturated-unsaturated porous media flow theory and Galerkin-type finite element techniques were applied.
The movements of the saturation (wetting) fronts and the pore pressure distributions in the earthfill and its foundation were used in the investigation of deformation and stability of the Guri earthfill dam under staged construction and reservoir filling.

CARACAS, Sep 14 (IPS) - Indigenous Venezuelans have knocked down seven electrical towers in the last two days that are part of the 1,500-km powerline system intended to carry electricity from the Guri dam in southeast Venezuela to the state of Roraima, in northern Brazil.
The state-run company 'Electrificación del Caroní' (EDELCA) discovered the damage and the government of Bolívar state, which covers 238,000 square km of the Venezuelan territory bordering Guyana, announced it would use police force to prevent the indigenous Pemón peoples from taking down more towers.
The 400-million-dollar project means the sale of electricity from the Guri dam (on the River Caroní, with a 12,00 megawatt capacity) to the Roraima region, as well as to the communities along the path of the electrical lines.
