Yobe River
The Yobe River, also known as the Komadougou Yobe also spelt Komadugu Yobe River or the Komadougou-Yobe (), is a river in West Africa that flows into Lake Chad through Nigeria and Niger. Its tributaries include the Hadejia River, the Jama'are River, and the Komadugu Gana River. The river forms a small part of the international border between Niger and Nigeria with 95 miles (150 km) and flows a total of 200 miles (320 km) There are concerns about changes in the river flow, economy and ecology due to upstream dams, the largest at present being the Tiga Dam in Kano State, with plans being discussed for the Kafin Zaki Dam in Bauchi State. The River Yobe provides a means of subsistence for hundreds of thousands of people who work in a variety of commercial and agricultural endeavours along its almost 200 km length in the state's northern region, which spans seven local government areas (LGAs) from Nguru to Yunusari.

Hadejia River
The Hadejia River ( Hausa: ) is a river in Northern Nigeria and is a tributary of the Yobe River (Komadugu Yobe). Among the cities and towns that lie on or near its banks are Hadejia and Nguru. Damming of the river for the purposes of irrigation has led to a decrease in the amount of water in the Hadejia-Nguru wetlands, which the river forms along with Nguru Lake. The Hadejia river is now 80% controlled by the Tiga and Challawa Gorge dams in Kano State. Flood The state government started clearing the Hadejia River's canal and preventing water overflows, after the state experienced significant flooding, this work was started to prevent future floods. Flood frequency analysis was performed on the maximum annual streamflow data for the River Hadejia gauge station from the Hadejia Jama'are Komadugu TrustFund, Damaturu, for the years 1963 to 2014. For the analysis, three probability distribution functions—Extreme Value Type 1 (EV-1), Lognormal, and Log Pearson Type I ...

Kafin Zaki Dam
The Kafin Zaki Dam is a controversial project to build a reservoir on the Jama'are River (also called the Bunga River in its upper reaches) in Bauchi State in the Northeast of Nigeria. Proposed dam and reservoir The proposed dam would be of zoned earthfill construction and would be 11 kilometres-long. It would be designed with the potential to install a 15 MW hydroelectric plant. The reservoir would have a storage capacity of 2,700 million cubic meters, and would be the second largest in Nigeria after the Kainji Dam. It would irrigate 120,000 hectares of arable land on which cash crops could be grown. Potentially the project would support production of one million tonnes of sugarcane annually and provide over one million jobs in industries related to agriculture. Project history The dam was first considered after the 1972-1974 drought in the Sahel, and during the Shehu Shagari regime in 1979-1982, a contract was awarded to Julius Berger Nigeria to build the dam. In 1984, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flooding
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding. Examples for human changes are land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees. Global environmental issues also influence causes of floods, namely climate change which causes an intensification of the water cycle and sea level rise. For example, climate change makes extreme weather events more frequent and stronger. This leads to more intense floods and increased flood risk. Natural types of floods include river flooding, groundwater flooding coastal flooding and urban flooding sometimes known as flash flooding. Tidal flooding may inclu ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...
