The Contrasting Colors of the Gigantic Lake Nasser

Stretching for almost 500 kilometers (300 miles) across Egypt and Northern Sudan, Lake Nasser is one of the largest man-made lakes in the world. The lake was created as a result of the structure of the Aswan High Dam on the Nile, and the interesting geology of the area gives the east and west banks a very different appearance.

Made in 1960sthis huge body of water has potential 168.9 billion cubic meters and shores of it 7,844 kilometers (4,874 miles). Despite having double shores the distance from London to Cairo, the lake is surprisingly shallow, with just average depth 25 meters (82 feet).

The area is composed of medium to coarse-grained sandstone, which forms the banks. difference in color. The west bank of the lake has a lot of tan-colored sand that covers the shore rocks, giving it a distinct yellow color.

As a result of weaker winds in the Nile Valley, sand is not carried across the lake to the nearby bank. Thus, the east bank, in contrast, is free of this yellow sand, leaving exposed gray rocks that create a much darker appearance.

Adding to the different appearance of the two banks, there is a shallower shore in the west that attracts wild animals. The east, however, is a rugged desert landscape with a less diverse ecosystem.

Due to its location on the border between Egypt and Sudan, the lake is divided into two territories. The two thirds that sit on the Egyptian side are called Lake Nasser after the country’s former president Gamal Abdel Nasserwho played a significant role in initiating the construction of the Aswan High Dam.

The remaining area in Northern Sudan is called Lake Nubia, named after the ancestral home of the Nubian peoplewhose farms and villages were flood during the construction of the dam. Aswan High Dam Estate 90,000 The Egyptians and the Sudanese nomads of Namibia who had to be resettled in the surrounding area.

The creation of the lake is also threatened displacement several significant historical artefacts, including the temples of Philae and Abu Simbel. To save these structures, the Egyptian government received help from UNESCO to remove the temples and carefully rebuild them in the surrounding area.

Working with to impound flood waters from the No, the Higher Dam it releases these waters when needed on irrigated land to enable crop growth in the dry and arid conditions of the region. The water reaches an additional 324,000 hectares of irrigated land and has converted 283,000 hectares of land from flood irrigation to flood irrigation. perennial irrigationwhich means that the crops receive a constant supply of water through canal distribution.

In addition to the agricultural progress, the 111-meter (364 feet) high dam also generates a huge amount of hydroelectric power using 12 turbines to create 10 billion kilowatt-hours per year.

Despite the beneficial results of the dam, its complete control over the annual flooding of the Nile is responsible for much of the river. 40 million tons of fertilizer silt to be stored in reservoirs and canals, to prevent it from being applied to other areas of the Nile farmland. As a result, Egypt uses about 1 million tons of artificial fertilizers per year to compensate for the land’s depleted nutrient source.
