Ruvuma
Ruvuma River, formerly also known as the Rovuma River, is a river in the African Great Lakes region. During the greater part of its course, it forms the border between Tanzania and Mozambique (in Mozambique known as ''Rio Rovuma''). The river is long, with a drainage basin of in size. Its mean annual discharge is at its mouth. Overview The lower Ruvuma river is formed by the junction at of two branches of nearly equal importance, the longer of which, the Lujenda, comes from the south-west, the other, which still bears the name Ruvuma, from the west. Its source lies on an undulating plateau, high, immediately to the east of Lake Nyasa, at , the head-stream flowing first due west before turning south and east. In its eastward course, the Ruvuma flows near the base of the escarpment of an arid sandstone plateau to the north, from which direction the streams, which have cut themselves deep channels in the plateau edge, have almost all short courses. On the opposite bank the ...

Lujenda River
The Lugenda or Lujenda (alternate: Msambiti River) is a river of northern Mozambique. It flows in a south-north direction from Lake Amaramba/Lake Chiuta and is the largest tributary of the Ruvuma River. It joins the Luambala River at . The river valley is reported to be only above sea level. North of Lake Chiuta, those on the west bank call it the Msambiti River. At one point, the Lugenda splits into several streams with islands between them, some of whom are populated such as the island Achemponda. Elephants loom large in the life of people of the Lugenda River Valley. The tribal people, inhabiting the river valley for several thousand years, are mainly the Yao and Makua tribals. Other groups residing here are Ngoni, Marave and Matambwe people. Etymology The etymology of the word Lugenda in Yao language, a Bantu language spoken by the Yao people (East Africa) in Africa}, has the literal meaning “a large river.” Geography The Lugenda River, which joins the main R ...

David Livingstone
David Livingstone (; 19 March 1813 – 1 May 1873) was a Scottish physician, Congregationalist, and pioneer Christian missionary with the London Missionary Society, an explorer in Africa, and one of the most popular British heroes of the late 19th-century Victorian era. David was the husband of Mary Moffat Livingstone, from the prominent 18th Century missionary family, Moffat. He had a mythic status that operated on a number of interconnected levels: Protestant missionary martyr, working-class "rags-to-riches" inspirational story, scientific investigator and explorer, imperial reformer, anti-slavery crusader, and advocate of British commercial and colonial expansion. Livingstone's fame as an explorer and his obsession with learning the sources of the Nile River was founded on the belief that if he could solve that age-old mystery, his fame would give him the influence to end the East African Arab–Swahili slave trade. "The Nile sources", he told a friend, "are valuabl ...

Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus ''Homo'' are found near Lake Olduvai. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ...

Mozambique
Mozambique (), officially the Republic of Mozambique ( pt, Moçambique or , ; ny, Mozambiki; sw, Msumbiji; ts, Muzambhiki), is a country located in southeastern Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. The sovereign state is separated from the Comoros, Mayotte and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Notably Northern Mozambique lies within the monsoon trade winds of the Indian Ocean and is frequentely affected by disruptive weather. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and language. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of t ...

Mozambican War Of Independence
The Mozambican War of Independence ( pt, Guerra da Independência de Moçambique, 'War of Independence of Mozambique') was an armed conflict between the guerrilla forces of the Mozambique Liberation Front or FRELIMO () and Portugal. The war officially started on September 25, 1964, and ended with a ceasefire on September 8, 1974, resulting in a negotiated independence in 1975. Portugal's wars against guerrilla fighters seeking independence in its 400-year-old African territories began in 1961 with Angola. In Mozambique, the conflict erupted in 1964 as a result of unrest and frustration amongst many indigenous Mozambican populations, who perceived foreign rule as exploitation and mistreatment, which served only to further Portuguese economic interests in the region. Many Mozambicans also resented Portugal's policies towards indigenous people, which resulted in discrimination and limited access to Portuguese-style education and skilled employment. As successful self-deter ...

Lake Chiuta
Lake Chiuta is a shallow lake on the border between Malawi and Mozambique. It lies to the north of Lake Chilwa and to the south of Lake Amaramba, which has no outlet, and the lakes are separated by a sandy ridge. Both lakes lie in a graben which runs northeast–southwest, east of the main African Rift Valley. Lake Chiuta is 3–4 meters deep and ranges in size from 25 to 130 square kilometers, depending on the season and rainfall. Lake Chiuta and Amaramba is intermittently linked to the Lugenda River, a tributary of the Ruvuma River. Lake Chiuta can desiccate completely (Owen et al. 198?)

Discharge (hydrology)
In hydrology, discharge is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids (e.g. sediment), dissolved chemicals (e.g. CaCO3(aq)), or biologic material (e.g. diatoms) in addition to the water itself. Terms may vary between disciplines. For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow, whereas an engineer operating a reservoir system may equate it with outflow, contrasted with inflow. Theory and calculation A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure. For measuring the discharge of a river we need a different method and the most common is the 'area-velocity' method. ...

Border Rivers
Borders are usually defined as geographical boundaries, imposed either by features such as oceans and terrain, or by political entities such as governments, sovereign states, federated states, and other subnational entities. Political borders can be established through warfare, colonization, or mutual agreements between the political entities that reside in those areas; the creation of these agreements is called boundary delimitation. Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded. Most external political borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints; adjacent border zones may also be controlled. Buffer zones may be setup on borders between belligerent entities to lower the risk of escalation. While ''border'' refers to the boundary itself, the area around the border is called the frontier.
