Titicaca Basin
Lake Titicaca (; ; ) is a large freshwater lake in the Andes mountains on the border of Bolivia and Peru. It is often called the highest navigable lake in the world. Titicaca is the largest lake in South America, both in terms of the volume of water and surface area.Grove, M. J., P. A. Baker, S. L. Cross, C. A. Rigsby and G. O.

Isla Del Sol
Isla del Sol (Spanish language, Spanish for "Island of the Sun") is an island in the southern part of Lake Titicaca. It is part of Bolivia, and specifically part of the La Paz Department (Bolivia), La Paz Department. Geographically, the terrain is harsh; it is a rocky, hilly island with many eucalyptus trees. There are no motor vehicles or paved roads on the island. The main economic activity of the approximately 800 families on the island is farming, with fishing and tourism augmenting the subsistence economy. Of the several villages, Yumani and Challapampa are the largest. There are over 80 ruins on the island. Most of these date to the Inca period circa the 15th century AD. Archaeologists have discovered evidence that people lived on the island as far back as the third millennium BC. Many hills on the island contain agricultural terraces, which adapt steep and rocky terrain to agriculture. Among the ruins on the island are Titi Qala (Aymara language, Aymara ''titi'' Andean mount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altiplano
The Altiplano (Spanish language, Spanish for "high plain"), Collao (Quechuan languages, Quechua and Aymara language, Aymara: Qullaw, meaning "place of the Qulla people, Qulla") or Andean Plateau, in west-central South America, is the most extensive high plateau on Earth outside Tibet. The plateau is located at the latitude of the widest part of the north–south-trending Andes. The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southwestern fringes lie in Chile. There are on the plateau many towns and several cities, including El Alto and Oruro, Bolivia, Oruro in Bolivia, Juliaca and Puno in Peru. The northeastern part of the Altiplano is more humid than the southwestern part, which has several Salt pan (geology), salares (salt flats), due to its aridity. At the Bolivia–Peru border lies Lake Titicaca, the largest lake in South America. Farther south, in Bolivia, there was until recently a lake, Lake Poopó, but by December 2015 it had complet ...

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Pollution In Peru
The principal environmental issues in Peru are water pollution, soil erosion, pollution and deforestation. Although these issues are problematic and equally destructive, the Peruvian Environmental ministry has been developing regulation and laws to decrease the amount of pollution created in major cities and have been making policies in order to decrease the present deforestation rate in Peru. Emissions The Economic Commission for Latin America and the Caribbean (ECLAC) estimates that the economic losses related to climate change could reach over 15% of national gross domestic product (GDP) by 2100. In 2010, Peruvian greenhouse gas emissions represented only 0.4% of global emissions. However, Air pollution, emissions are rising nationwide – particularly in the energy and transport sectors. In an effort to combat this, the Government of Peru approved a law to establish a national greenhouse gas inventory system called INFOCARBONO. INFOCARBONO will enable different ministries to ...

Al Jazeera Arabic
Al Jazeera Arabic ( , ) is a Qatari state-funded Arabic-language news television network. It is based in Doha and operated by the Al Jazeera Media Network, which also operates Al Jazeera English. It is the largest news network in the Middle East and North Africa region. It was founded in 1996 by the then Emir of Qatar Sheikh Hamad bin Khalifa Al Thani. Noted for its journalistic professionalism, especially when contrasted with other Arab news organizations, Al Jazeera gained popularity in the Arab world as an alternative to the previous landscape of largely local state-owned broadcasters, with its early coverage being openly critical of autocratic leaders in the region, as well as hosting a wide range of viewpoints, gaining credibility through its extensive frontline coverage of the Second Intifada and the Iraq War. Al Jazeera Arabic is editorially independent from Al Jazeera English. History Launch and initial coverage (1996–1999) Al Jazeera Satellite Channel, now k ...

Evapotranspiration
Evapotranspiration (ET) refers to the combined processes which move water from the Earth's surface (open water and ice surfaces, bare soil and vegetation) into the Atmosphere of Earth, atmosphere. It covers both water evaporation (movement of water to the air directly from soil, Canopy interception, canopies, and water bodies) and transpiration (evaporation that occurs through the stomata, or openings, in plant leaves). Evapotranspiration is an important part of the local water cycle and climate, and measurement of it plays a key role in water resource management Irrigation, agricultural irrigation. Definition ''Evapotranspiration'' is defined as: "The combined processes through which water is transferred to the atmosphere from open water and ice surfaces, bare soil and vegetation that make up the Earth’s surface." Evapotranspiration is a combination of evaporation and transpiration, measured in order to better understand crop water requirements, irrigation scheduling, and ...

Water Balance
The law of water balance states that the inflows to any water system or area is equal to its outflows plus change in storage during a time interval. In hydrology, a water balance equation can be used to describe the flow of water in and out of a system. A system can be one of several hydrological or water domains, such as a column of soil, a drainage basin, an irrigation area or a city. The water balance is also referred to as a water budget. Developing water budgets is a fundamental activity in the science of hydrology. According to the US Geological Survey: Equation for a basin A general water balance equation is: : where : is Precipitation (meteorology), precipitation : is streamflow : is evapotranspiration : is the change in storage (in soil or the bedrock / ground water, groundwater) This equation uses the principles of conservation of mass in a closed system, whereby any water entering a system (via precipitation), must be transferred into either evaporation, trans ...

Lake Poopó
Lake Poopó ( ) was a large saline lake in a shallow depression in the Altiplano in Oruro Department, Bolivia, at an altitude of approximately . Due to the lake's length and width (), it made up the eastern half of Oruro, known as a mining region in southwest Bolivia. The permanent part of the lake body covered approximately and it was the second-largest lake in the country. The lake received most of its water from the Desaguadero River, which flows from Lake Titicaca at the north end of the Altiplano. Since the lake lacked any major outlet and had a mean depth of less than , the surface area differed greatly seasonally. In 2002, the lake was designated as a site for conservation under the Ramsar Convention. By December 2015, the lake had completely dried up, leaving only a few marshy areas. Despite the lake rebounding from two previous recorded drying instances, as of 2016, the lake's recovery is considered unlikely. Suggested causes of the decline are the melting of the A ...

Desaguadero River (Bolivia And Peru)
The Desaguadero River, also known as Risawariru or Uchusumain, is a river shared between Bolivia and Peru. It drains Lake Titicaca from the southern part of the river basin, flowing south and draining approximately five percent of the lake's flood waters into Lake Uru Uru and Lake Poopó. Its source in the north is very near the Peruvian border. It is navigable only by small craft and supports indigenous communities such as the Uru Muratu community. See also * Awallamaya Lake * Desaguadero River (Argentina) from Argentina Argentina, officially the Argentine Republic, is a country in the southern half of South America.

Monomictic
Monomictic lakes are holomictic lakes that mix from top to bottom during one mixing period each year. Monomictic lakes may be subdivided into cold and warm types. Cold monomictic lakes Cold monomictic lakes are lakes that are covered by ice throughout much of the year. During their brief "summer", the surface waters remain at or below 4 °C. The ice prevents these lakes from mixing in winter. During summer, these lakes lack significant thermal stratification, and they mix thoroughly from top to bottom. These lakes are typical of cold-climate regions (e.g. much of the Arctic). An example of a cold monomictic lake is Great Bear Lake in Canada. Warm monomictic lakes Warm monomictic lakes are lakes that never freeze, and are thermally stratified throughout much of the year. The density difference between the warm surface waters (the epilimnion) and the colder bottom waters (the hypolimnion) prevents these lakes from mixing in summer. During winter, the surface waters cool to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
