Which has more sediment in the White Nile or the Blue Nile?

The Blue Nile contains more sand than the White Nile, depending on the area and topography through which it flows.

The Kagara River, the upper source of the Nile, originates in the Burundi Highlands of the East African Highlands, flows north through Lake Victoria, and is called the White Nile at Nemulai on the border between Sudan and Uganda. The upper reaches of the Nemoulay continue north to Khartoum, Sudan, where they join the Blue Nile, forming the main stream of the Nile, and below Khartoum is the lower reaches and flow north into the Mediterranean.

The White Nile above Khartoum flows through equatorial rainy areas (tropical rainforest and savannah climate zones) with less seasonal variation in runoff.

The Blue Nile originates from the Ethiopian plateau in the Savannah (savannah) climate, and the runoff varies greatly from season to June, and carries a large amount of fertile soil into the main stream of the Nile, causing regular flooding in the lower reaches of the Nile and forming a fertile delta. The amount of water during the flood season comes mainly from the Blue Nile, and the water volume during the dry season comes mainly from the White Nile.

The landform of the basin can be summarized as follows: the East African Plateau, which is mainly composed of crystalline rocks, and the Ethiopian Plateau, which is composed of lava, are located on the south and southeast sides of the basin, respectively. The whole of Sudan is basically a huge tectonic basin with a slight dip from south to north, with the Nile River running through it; Below Khartoum, the Nile is flanked by vast desert plateaus on the east and west. From the longitudinal profile of the riverbed, the specific decline of the Nile section shows obvious steep and gentle alternating changes.

It can be seen that the sediment mainly comes from the Blue Nile. The average annual sediment transport in Aqiwan, Egypt is 13.4 billion tons, and the average sediment content is about 5 6 kg m3.

What is the specific reason, the person in front of me has made it very clear.

However, it seems that the landlord has a problem and thinks wrong.

The White Nile is actually the upper part of the Nile, and the Nile does flow through the desert, but the White Nile does not. The climate of the place through which it flows is a tropical sparse forest steppe climate. Rainfall is abundant and average, and seasonality is not significant.

And it originated in Lake Victoria on the East African plateau. The amount of cement and sand in the river is relatively small.

As for the Blue Nile River, it originates in the mountains, and the seasonality is obvious, that is, there is a lot of precipitation in the summer, and the downstream floods, the water is big, and there is a lot of sediment washed down, and there is a lot of sediment in the mountains itself

Blue Nile, Reason: The river flows mainly through the savannah climate zone, with concentrated precipitation during the rainy season. The terrain of the flowing area is large (or the river drop is large), and the erosion effect of flowing water is strong.

Blue Nile! The Blue Nile River is located in the savannah climate zone, with obvious dry and wet seasons.

The Nile River does not seem to have a large sediment content. The picture below is the Nile River near Luxor, which basically belongs to the middle and lower reaches of the river, and the river water is very clear.

The Nile River is long and flows through tropical rainforests, savannahs, tropical deserts and other climatic zones, with large seasonal changes in runoff, high sediment content, large runoff (large irrigation along the way), and ice-free periods.

The area through which the Nile passes is not covered by vegetation and the dry steppe and desert are vast, and these areas provide abundant sediment, so the sand content is high.

The Nile is a river that flows through eastern and northern Africa and flows from south to north into the Mediterranean Sea. Along with the Congo River in Central Africa and the Niger River in West Africa, it is one of the three largest river systems in Africa. At 6,670 km long, the Nile is the longest river in the world.

The Nile has two main tributaries, the White Nile Kwana Liquid River and the Blue Nile River. The Blue Nile, which originates in the Ethiopian highlands, is the lower reaches of the Nile and is the most water and nutrient**, but the White Nile is the longest of the two tributaries.

The White Nile River flows through the savannah climate zone, and the basin area is wider, and the savannah climate is divided into dry and wet seasons, although the Blue Nile River is also part of the savannah climate zone, but its basin area is more in the tropical desert climate zone and it is more fed by ice and snow meltwater.

Therefore, the flow of the White Nile is greater than that of the Blue Nile, and the water supply of the Nile in summer is mainly the White Nile, while the water source in winter is mainly the Blue Nile.

Did the landlord write it backwards? It should be that the volume of the Blue Nile varies more from season to season, while the White Nile changes less.

The Blue Nile River mainly flows through the savannah climate zone of the Northern Hemisphere, and the runoff of the Blue Nile River also shows very obvious seasonal changes due to the obvious dry and wet seasonal changes in the climate in the basin. The White Nile also flows through a large area of savannah climate zone, but it originates in the savannah climate zone of the southern hemisphere, and flows through the savannah climate zone of the northern hemisphere at the same time, so there is a phenomenon, that is, when the savannah in the northern hemisphere enters the dry season, the tropical grass principle in the southern hemisphere enters the wet season, and when the savannah in the northern hemisphere enters the wet season, the savannah in the southern hemisphere enters the dry season, plus in the long flow process, The evaporation caused the White Nile to lose a significant amount of runoff (in the Nile, the Blue Nile accounts for 60% of the runoff, while the White Nile accounts for only 32%), so the seasonal variation of the White Nile is also much smaller than that of the Blue Nile.

The source water volume of the Blue Nile River and the White Nile River is larger, but the difference is that the Blue Nile River flows through the area has a large terrain difference and a fast flow rate. However, the White Nile River has a large amount of flat terrain after exiting the plateau, coupled with high temperatures, and the dry climate leads to violent evaporation, resulting in a significant reduction in its downstream flow.

The Nile River has two sources, one originates in the 2,621-meter tropical Central African mountains, called the White Nile. The White Nile flows through vast lake areas such as Lake Victoria and Lake Kioga, through the jungles of Uganda, and north through Sudan.

The other source of the Nile is in the Ethiopian highlands at an altitude of 2,000 meters. It's called the Blue Nile. The 680-kilometre-long Blue Nile River crosses Lake Tana and then plummets down to form a cascading stream that is known as the second largest waterfall in Africa, Tisset Falls.

The Blue Nile River enters the Sudan Plain and joins the White Nile, which is known as the Nile.

Because it flows through the tropical rainforest area, the water is abundant, the vegetation is good, and the water is clear, so it is called the White Nile River.

Because of the seasonal river, the river dries up in winter, the river water quickly in summer**, and it is a savannah, so it is called the Blue Nile.
