What is Bulozi flood plain system?
The Barotse Floodplain, also known as the Bulozi Plain, Lyondo or the Zambezi Floodplain, is one of Africa’s great wetlands, on the Zambezi River in the Western Province of Zambia. It is a designated Ramsar site, regarded as being of high conservation value.
What process creates floodplains?
Formation. Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Wherever the river meanders, the flowing water erodes the river bank on the outside of the meander, while sediments are simultaneously deposited in a point bar on the inside of the meander.
Are floodplains man made?
Recharging groundwater For many decades, communities have built structures such as dams and levees (linear earthen berms built alongside a river) to keep flood water from damaging homes and businesses built on floodplains. These man-made structures age and are not always effective against the largest floods.
Is floodplain farming good?
floodplains are usually very fertile agricultural areas. Floods carry nutrient-rich silt and sediment and distribute it across a wide area. floodplains are flat and often have relatively few boulders or other large obstacles that may prevent farming.
Where is Barotseland located?
Barotseland (Lozi: Mubuso Bulozi) is an unrecognized kingdom between Namibia, Botswana, Zimbabwe, Zambia and Angola.
What Causes floodplain erosion?
The clearing of catchments for agriculture and urban development has aggravated floodplain erosion for two reasons, firstly due to changes in surface and groundwater discharge and secondly due to loss of soil strength.
How are levees and floodplains formed?
The natural movement of a body of water pushes sediment to the side, creating a natural levee. The banks of a river are often slightly elevated from the river bed. The banks form levees made of sediment, silt, and other materials pushed aside by the flowing water.
Why are floodplains good?
Floodplains are beneficial for wildlife by creating a variety of habitats for fish and other animals. In addition, floodplains are important because of storage and conveyance, protection of water quality, and recharge of groundwater.
Why are flood plains very fertile?
Flood plains are naturally very fertile due to the river sediment which is deposited there. This sediment is good for growing plants on the flood plain.
What crops grow best in floodplains?
Soybeans are another crop commonly found in floodplains. Farmers often plant both corn and soybeans, alternating between the two crops. Using the two in this way offers several advantages to farmers. First, soybeans provide a natural fertilizer by fixing nitrogen from the atmosphere, creating nitrogen-rich soils.
Who is the founder of the Lozi kingdom?
According to myth, the Lozi tribe began when the sun god Nyambe descended from heaven onto Barotseland, which is the Lozi homeland. He came with his wife Nasilele (the moon), and together they began the line of Luyi-Luyana kings.
Who led the Lozi from Katanga?
-There is a lot of tradition and little certainty. However, strong evidence links them to the Luba-Lunda parent area in Katanga. -During the 17th century, around 1650, Mwambwa, a semi-mythical or divine woman, led the Luyi along the Kabompo River into the upper Zambezi plain.
How does a floodplain build up over time?
Floodplains form due to erosion and deposition. Erosion removes any interlocking spurs, creating a wide, flat area on either side of the river. During a flood, the material being carried by the river is deposited (as the river loses its speed and energy to transport material).
How levees are created?
Levees are usually made of earth. The natural movement of a body of water pushes sediment to the side, creating a natural levee. The banks of a river are often slightly elevated from the river bed. The banks form levees made of sediment, silt, and other materials pushed aside by the flowing water.
How are river floodplains formed?
A floodplain is a wide, flat area of land either side of a river in its lower course. The floodplain is formed by both the processes of erosion and deposition. Lateral erosion is caused by meanders and their associated river cliffs and the slow migration of meanders downstream.
Why are floodplains so popular for developers?
Flood plains are often more attractive to developers because they tend to be flat and therefore easy to build on and close to other amenities such as transport and utilities networks.
What is the Barotse Floodplain?

It is a designated Ramsar site, regarded as being of high conservation value. The name recognises the floodplain as spawning…
What do the Lozi do in the floodplain?
The floodplain is one of the most productive areas for raising cattle in the country. The Lozi also catch fish, eating about five times as much as the national average. At the height of the flood they use fish traps and spears for fishing, and they use gill nets in the lagoons left behind by the falling flood.
What is the significance of the floodplain in Zambia?
The floodplain determines and dominates the way of life, economy, society and culture of the Lozi, who are skilled boat-builders, paddlers and swimmers. The annual migration with the flood is celebrated in the Kuomboka ceremony held at Mongu, capital of Barotseland and its successor, the Western Province.
Where is the floodplain located in Africa?
The floodplain stretches from the Zambezi’s confluence with the Kabompo and Lungwebungu Rivers in the north, to a point about 230 km south, above the Ngonye falls and south of Senanga. Along most of its length its width is over 30 km, reaching 50 km at the widest, just north of Mongu, principal town of the plain,…
