Rivers are important natural geographical elements. Above-ground rivers belong to the category of surface runoff, and underground rivers belong to the category of groundwater.Since ancient times, human beings have lived by rivers, which play an extremely important role for human beings. Rivers play a variety of functions such as water supply, shipping, breeding, beautification of the environment, climate regulation, and biodiversity protection.According to whether or not rivers eventually enter the sea, they can be divided into outflow rivers and internal rivers.The volga, Syr, Amu darya, Ural, Tarim and Shabelle rivers are the six longest rivers in the world.Today we tell about the seventh to ninth most flowing rivers in the world. They are the Okavango, The Sari and the Kula.The Okavango River is located in south-central Africa, located in the southern hemisphere. It originates from the Bi Plateau in southern Angola. It is about 1500 to 2000 meters above sea level and is known as the roof of Angola.The Okavango River flows from northwest to southeast through Namibia and Botswana before disappearing into the Okavango Delta.The Tuokavango river, with a drainage area of about 800,000 square kilometers and a flow of about 1,600 kilometers, is the fourth longest river in southern Africa and the seventh largest inland river in the world.The climate of the region where the Okavango River basin is located is savanna climate, and the precipitation season varies greatly, with obvious rainy season and dry season in a year, so the runoff of the Okavango River varies greatly in season.In the rainy season, the okavango river water volume increases, runoff, river erosion is strong, the pentium of the river carrying a large number of silt into the Okavango delta, in the continuous deposition of silt, the formation of the world’s largest inland delta, delta area of about 15,000 square kilometers, is a paradise for wildlife.Mr Which a river delta sand is also an inward flowing river in northern Africa, originated in the central African republic, Ming ji – class of zerah golan province, near the overall to flow from the southeast to the northwest, along the way of acceptance of the silo rhue GeLanHe state, Gerry bin river gee, and river, river, middle and lower reaches in Chad, eventually into the lake Chad,It is an important inflow river to Lake Chad.The Sari River basin covers a total area of about 650,000 square kilometers and flows about 1,400 kilometers, making it the eighth longest inland river in the world.The main climate type in the Shali River basin is also the savanna climate. In the summer of the Northern hemisphere, the pressure belt and the wind belt move northward. This area is controlled by the equatorial low pressure belt, and the prevailing updraft increases the precipitation and enters the rainy season.At this time, the sand river runoff increases, into the flood season in a year, the river is very wide, part of the width of the river can reach more than 5 kilometers.In winter in the northern hemisphere, the pressure belt moves southward, and this area is controlled by the northeast trade wind belt. The dry trade wind is difficult to form clouds and rain, and enters the dry season.At this time, the sand river runoff reduced, into the dry season of the year.At this time, there is very little water in the Sandy River, and sometimes the channel becomes a series of stagnant ponds.The Shari river and the Chad Kula River, located in Eurasia, is an international river in transcaucasia and the largest river in the region.The Kula River rises on the Armenian Plateau in Turkey, a lava-covered plateau averaging between 1,500 and 2,000 meters above sea level. After its origin, the Kula river twists and turns eastward through countries such as Georgia and Azerbaijan before empting into the Caspian Sea.The Kula River basin covers a total area of about 188,000 square kilometers and flows about 1,364 kilometers, making it the ninth longest inland river in the world.The Tukula river has a large drop, forming a series of canyons as it flows through the Lesser Caucasus Mountains. It is ideal for the construction of hydropower stations. Four hydropower stations have been built on the main stream of the Kula River, and the Kula river is an important irrigation source in the region.In the middle and upper reaches of kula River, the flow velocity is fast, the water erosion ability is strong, the river sediment content is large, the river carries the sediment to deposit in the lower reaches of Kula River, and forms an estuary delta with an area of about 100 square kilometers.Due to the continuous deposition of sediment carried by the Kula River, the delta is continuously pushed towards the Caspian Sea, about 100 meters per year.Mr Khoja river
