What is the water table in the desert and what is the water table in the Tengger Desert

Deserts are excellent natural reservoirs. Deserts usually have a thick layer of loose sand underneath the basin and are located in a water-collecting position in the lower terrain of the basin. There are large pores between the sand grains to store water, and a large area of sandy sediment under the desert is like a huge water storage container.

The dry sand layer on the surface acts like the lid of the reservoir, blocking the sun and preventing the groundwater from evaporating. It is for this reason that many deserts have abundant groundwater. The largest desert in our country?

Taklamakan Desert, Xinjiang.

The groundwater level is generally not lower than 10 meters above the surface of the mound, and it is very convenient to drill wells for use. In other deserts, the water table may be even higher.

Desert groundwater is mainly used for the recharge of desert rivers. Rivers infiltrate in the desert, diverting groundwater away from the river. In general, the salinity of groundwater becomes heavier the farther away from the river.

Rainwater contributes only a small amount to groundwater, as precipitation in arid regions is pitiful.

Groundwater levels have a significant impact on desert formation. Just as a wick can make the lamp oil rise, the sand can cause water to seep up from the groundwater surface for a certain distance, forming a layer of wet sand above the groundwater surface, which is called capillary action. The corresponding wet sand layer is also called capillary belt.

A wet sand layer with a capillary belt is often the limit of wind-eroded terrain. However, in the process of the development of sand dunes by wind erosion of the dry sand layer, on the one hand, the accumulation of sand dunes became higher, and on the other hand, the interhilaly land in the wind erosion area became lower due to erosion. However, when the erosion zone is as low as the wet sand layer in the capillary zone, the wind erosion is blocked, and the horizontal erosion surface is formed, and the adjacent sand dunes will stop increasing due to the lack of sand sources.

It can be seen that the decline of the groundwater level will lead to the formation of tall sand dunes, and the rise of the groundwater level may cause the sand dunes to become lower. The formation of tall sand mountains in many deserts is actually associated with low or long-term decline in groundwater levels.

The water table in deserts is often tens or even hundreds of meters below the soil.

This depends on the actual situation, but it is generally very low, and there are also those on the ground, such as the sun and the moon.

Hello! We'll be happy to answer for you. The groundwater level in the Tengger Desert is 1-2 meters, and the Tengger Desert is located in the southwest of the Alxa Zuoxian Banner of the Inner Mongolia Autonomous Region and the central border of Gansu Province, between 37°30 to 40°N latitude and 102°20 to 106°E longitude.

The Great Wall of South Vietnam, east to Helan Mountain, west to Yabulai Mountain. It is 240 kilometers long from north to south and 160 kilometers wide from east to west, with a total area of about 10,000 square kilometers, making it the fourth largest desert in China. It is the eastern part of the Alxa Desert, at the bottom of the Yin'e Basin.

The administrative division of the Tengger Desert mainly belongs to the Alxa Left Banner, and the western and southeastern edges belong to Wuwei Minqin County in Gansu and Zhongwei City in Ningxia respectively. The desert includes two parts, Nanjiling in the north and Tengger in the south, and is customarily referred to as the Tengger Desert. There are staggered distribution of sand dunes, lake basins, grasslands, mountains, remnant hills and plains in the interior.

The sand dunes account for 71% of the area, mainly mobile dunes, mostly lattice dune chains and crescent-shaped dune chains, with heights ranging from 10 to 20 m (33 to 66 ft). There are a total of 422 lake basins, half of which are waterlogged, and are remnants of dried up or retreating.

Desert areas are dry and water-scarce, because the desert has a strong water seepage capacity and at the same time evaporates quickly, it can be considered that there is water in the desert will not be on the surface, and the groundwater will be deep, so it is quite difficult to dig wells in the desert to get water.

Ben believes that it is possible to dig more than 100 meters in a desert area and get water.

There are a lot of mistakes in your understanding.

First of all, deserts are not all no-man's land.

Especially the recently reported Tengger Desert.

Secondly, the underground of the desert is not without groundwater, and due to the special geological structure of the Tengger Desert, its groundwater can be said to be extremely rich compared to other deserts, and there are thousands of lakes in the Tengger Desert. In some places, you only need to dig a few meters down, and you can see the groundwater.

Again, the desert is also a cornucopia.

It's not that it's worthless, it's just that we're using it in the wrong way. The desert has light, heat, and land resources, as well as sand and gravel, which are incomparable to other places.

Resource. The sand fixation capacity caused by coagulation waste is negligible compared to its harm. This waste is not concrete, and when it dries, it will still fly all over the sky when the wind blows.

Moreover, most of these wastes volatilize harmful gases. These wastes can also leach into the groundwater.

There is groundwater in the desert, some of which is deeper, and some of which are shallow (on paleochannels).

Oases in the desert are often formed by the gushing of groundwater.

1.What is the water table refers to the distance from the liquid level to the ground.

2.If the water level of the desert is not low, it will evaporate quickly, and it is difficult to store water for sand. The grasslands have normal rainy and dry seasons, but the grass in the grasslands is covered with mud so it can hold water, and the temperature in the grasslands is not as high as in the desert.

3.The high water level of the washing machine is set low for the laundry, and the reverse is true.

1.What is a water table? - refers to the distance from the free liquid level to the ground.

2.Why is the desert water level lower....The water level in the grasslands is higher - the climate of the desert is drier than the grassland, and there is less precipitation, and the water table is naturally lower when there is less precipitation.

3.What's the deal with the high and low water levels of the washing machine? - The high and low water level of the washing machine is located according to the number of clothes, and the water above the high level will automatically flow out of the washing machine through the overflow pipe.

Absolutely.

There is also groundwater in a large area of desert in the northwest of China. However, the groundwater has a large burial depth, many types of groundwater occurrence, and the saltier groundwater is higher, that is, the salinity is higher.

The United Arab Emirates is located in the eastern part of the Arabian Peninsula. Except for a small number of low mountains and hills in the east and northeast, most of the country is a desert plain with an altitude of less than 200m, which belongs to the tropical desert climate. The average annual rainfall is less than 100mm, mainly in winter.

The country's rivers and lakes are dry, and its water supply is largely dependent on desalination and groundwater extraction, making it one of the driest countries in the world. In recent years, with the development of industrial and agricultural production and the increase of population in the country, the water demand has been increasing, the groundwater level has been declining year by year, and the contradiction between supply and demand has become increasingly prominent. The Al Ain region is the richest region in the UAE and is of great importance due to the scarcity of surface water resources.
