India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area; the most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Myanmar, Thailand, and Indonesia.

Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago. Their long occupation, predominantly in isolation as hunter-gatherers, has made the region highly diverse. Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By 1200 BCE, an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest. Its hymns recorded the early dawnings of Hinduism in India. India's pre-existing Dravidian languages were supplanted in the northern regions. By 400 BCE, caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. Early political consolidations gave rise to the loose-knit Maurya and Gupta Empires. Widespread creativity suffused this era, but the status of women declined, and untouchability became an organised belief. In South India, the Middle kingdoms exported Dravidian language scripts and religious cultures to the kingdoms of Southeast Asia.

Pahang (Malay pronunciation: [paˈhaŋ]; Pahang Hulu Malay: Paha, Pahang Hilir Malay: Pahaeng, Ulu Tembeling Malay: Pahaq), officially Pahang Darul Makmur with the Arabic honorific Darul Makmur ("The Abode of Tranquility") is a sultanate and a federal state of Malaysia. It is the third largest state in the country and the largest state in Peninsular Malaysia, and the ninth most populous. The state occupies the basin of the Pahang River, and a stretch of the east coast as far south as Endau. The state borders the Malaysian states of Kelantan and Terengganu to the north, Perak, Selangor and Negeri Sembilan to the west and Johor to the south, with the South China Sea is to the east. Pahang is separated from the west coast states by the Titiwangsa Mountains that forms a natural divider between the peninsula's east and west coasts from north to south, and from Terengganu in the east by the Pantai Timur Range. The state's highest elevation culminates at Mount Tahan in the eponymous Tahan Range, which is 2,187 metres (7,175 ft) high. Although two thirds of the state is covered by dense rain forest, its central plains are intersected by numerous rivers, and along the coast there is a 32-kilometre (20 mi) wide expanse of alluvial soil that includes the deltas and estuarine plains of the Kuantan, Pahang, Rompin, Endau, and Mersing Rivers.

The state is divided into 11 districts (daerah) – Pekan, Rompin, Maran, Temerloh, Jerantut, Bentong, Raub, Lipis, Cameron Highlands and Bera. The largest district is Jerantut, which is the main gateway to the Taman Negara national park. Pahang's capital and largest city, Kuantan, is the eighth largest urban area by population in Malaysia. The royal capital and the official seat of the Sultan of Pahang is located at Pekan. Pekan was also the old state capital and its name translates literally into 'the town', it was known historically as 'Inderapura'. Other major towns include Temerloh, Raub, Bentong, Jerantut, Kuala Lipis and its hill resorts of Genting Highlands, Bukit Tinggi, and Cameron Highlands. The head of state is the Sultan of Pahang, while the head of government is the Menteri Besar. The government system is closely modelled on the Westminster parliamentary system. The state religion of Pahang is Islam, but allows other religions in its territory.

Bandung is the capital city of the West Java province of Indonesia. Located on the island of Java, the city is the third largest city in Indonesia and Greater Bandung (Bandung Basin Metropolitan Area / BBMA) is the country's second-largest and second most populous metropolitan area, with over 11 million inhabitants. Situated 708 meters (2,323 feet) above sea level (the highest point in the North area is at an altitude of 892 meters (2,927 feet), and the lowest in the South at 666 meters (2,185 feet) above sea level), approximately 135 kilometres (84 miles) southeast of Jakarta, Bandung has cooler year-round temperatures than most other Indonesian cities. The city lies in a river basin surrounded by volcanic mountains that provide a natural defense system, which was the primary reason for the Dutch East Indies government's plan to move the capital from Batavia (modern-day Jakarta) to Bandung.

The Dutch first established tea plantations around the mountains in the 18th century, and a road was constructed to connect the plantation area to the colonial capital Batavia (180 kilometres (112 miles) to the northwest). In the early 20th century, the Dutch inhabitants of Bandung demanded the establishment of a municipality (gemeente), which was granted in 1906, and Bandung gradually developed into a resort city for plantation owners. Luxurious hotels, restaurants, cafés, and European boutiques were opened, leading the city to be nicknamed Parijs van Java (Dutch: "The Paris of Java").

Aburrá Valley (in Spanish Valle de Aburrá), is the natural river basin of the Medellín River and one of the most populous valleys of Colombia in its Andean Region with near 4 million inhabitants in its biggest urban agglomeration: The Metropolitan Area of the Aburrá Valley. The valley is located on the Central Range, over the Antioquian Mountain just between the Magdalena and Cauca valleys from east to west. The name "Aburrá" comes from an ancient language spoken in the place by the "Aburreans" (Aburraes) before the Spaniards settled the place during the 16th century.

The valley is oriented from south to north being the south the highest level and the north the low level. The altitudes of the mountains around the valley (west and east mountains), can reach up to 3,100 m (10,200 ft) above the sea level (Padre Amaya Peak). The lowest level is 1,300 m (4,300 ft) above sea level. From its north natural limit to its southern part, the valley is 60 km (37 mi) long, while there are several varieties in its width being the wider part the one that corresponds to the municipality of Medellín with 8–10 km (5.0–6.2 mi) and the narrowest the part that corresponds to the municipality of Copacabana with 3 km (1.9 mi).

This article contains a sortable table listing all major lakes of Switzerland. The table includes all still water bodies located either entirely or partly in Switzerland, both natural and artificial, that have a surface area of at least 30 hectares (74 acres), regardless of water volume, maximum depth or other metric. These lakes are ranked by area, the table including also the elevation above sea level and maximum depth. They are either natural (type N), natural but used as reservoirs (NR) or fully artificial (A).

Along with the mountains, lakes constitute a major natural feature of Switzerland, with over 1,000 km (620 mi) of shores within the country. Lakes, large and small, can be found in almost all cantons and provide an important source of water, leisure opportunities, as well as suitable habitat for fish-eating birds. The two most extensive, Lake Geneva and Lake Constance, are amongst the largest in Europe and mark the border of the Swiss Plateau, along with the Alps and the Jura Mountains. The largest wholly Swiss lake is Lake Neuchâtel. The remaining lakes over 100 km (39 sq mi) are Lake Maggiore and Lake Lucerne. In total 103 lakes exist that are more than 30 ha (74 acres) in surface area, and a considerable number of smaller lakes. All these lakes are found in the four major river basins of Switzerland: Rhine, Rhone, Po and Danube, at almost all elevations below the permanent snow line.

Yemaek or Yamaek 濊貊 were a people of Koreans who resided in ancient Manchuria. Whether they were: homogenous; heterogenous of Ye 濊 and Maek 貊; or whether Yemaek were a branch of Maek remains debated. However, the most accepted model is that they were ethnolinguistically identical but remained socially and politically disparate identities. The first Yemaek state to appear were 朝鮮 (Joson) that fell in 108 BC. They were renamed Old Joson after Joson Kingdom were later founded in 1392 AD: ostensibly as a successor state to Old Joson. Yemaek together with Han 韓 acted as the foundations for the formation of the Korean national identity. Of the three kingdoms who succeeded in forming centralised bureaucracy, 高句麗 (Gogooryo) had the strongest connection with Yemaek whereas 新羅 (Silla) had stronger Han identity and 百濟 (Baekje) were considered something in-between. Thus, the study of Yemaek is inevitably centralised around Gogooryo.

It remains controversial whether Gogooryo were: Ye; Maek; Yemaek; a branch of Yemaek; or Ye whose exonym were Maek due to sparse indigenous sources. However, it does appear Gogooryo had been an accumulation of many peoples such as Daesoo Maek (大水貊), Sosoo Maek (小水貊) and purportedly Yang Maek (梁貊). Furthermore, people who resided in the river basin of Amnok River began to be referred to as Maek somewhere near Anno Domini and it's hypothesised they amalgamated with Ye whom migrated from Booyo. They further accelerated their expansion by further conquering nearby tribes, thus forming a unified Yemaek identity under one sovereign.

Cayambe is a canton in the northeast of the province of Pichincha, in northern Ecuador, South America. The canton is named after the Cayambe, a 5,800-meter-high snow-covered stratovolcano in the east of the canton. The main part of the canton occupies the eastern portion of the Pisque river basin and is surrounded by volcanoes.

The seat of the canton, also named after the volcano, is Cayambe. The economy of the canton is agricultural, based on raising cattle and producing dairy products and growing flowers for export in greenhouses, and also cereals for local consumption. The Swiss food company Nestlé and the Cayambean company Miraflores have dairy-product factories in the city of Cayambe.

Ukraine has around 23,000 rivers, with most of the rivers draining into the Black Sea and Azov Sea and belonging to the larger Mediterranean basin. Those rivers mostly flow in a southerly direction, except for the Pripyat tributaries in Volhynia and Dniester tributaries in Prykarpattia. A few western Ukraine rivers drain to the north west through Poland to the Baltic Sea, as part of the Western Bug drainage basin. The most notable rivers of Ukraine include the Dnieper, Dniester, Southern Bug, and Siverskyi Donets. The longest river is the Dnieper, the longest tributary is the Dnieper's tributary Desna. Two of the Danube's tributaries in Ukraine, the Prut and the Tysa, are longer than the main river within Ukraine.

In 2013, in accordance with the Water Framework Directive (WFD), the territory of Ukraine has been divided into nine hydrographic zones (uk) according to major river basins, including the basins of the Vistula (Western Bug and San), Danube, Dniester, Southern Bug, Dnieper, Don, the rivers of the Black Sea littoral, the Sea of Azov littoral, and separately the rivers of Crimea. The biggest river basin by area is the Dnieper which is subdivided into the Pripyat basin, Desna basin, basin of Middle Dnieper, basin of Lower Dnieper. Beside Dnieper, basin of the Danube zoning is also subdivided into basin of Tysa, basin of Prut and Siret, and basin of the Lower Danube.
