How to find water in the desert?How to find water in the desert, and what are the scientific and eff

Since the temperature of day and night varies greatly in desert areas, fresh water can be obtained by condensation. The way to do this is to dig a pit in the ground with a diameter of about 90 centimeters and a depth of 45 centimeters. The air and soil in the pit heat up rapidly, producing steam.

When the water vapor reaches saturation, it will condense into water droplets on the inside of the plastic sheet, which will drip into the container below, so that we can get precious water, in desert areas with a large temperature difference between day and night, at least more than 500 ml of water can be obtained in a day and night. In this way, it is also possible to distill and filter dirty water that cannot be directly consumed. Most animals drink water regularly.

Herbivores do not stay away from water sources, they usually go to a fixed place to drink in the early morning and dusk, and can generally find water sources by finding them on the trails they often pass by and look for lower ground. <>

Look for plants with water signs The ground is relatively humid, and water sources can generally be found around plants such as sage, white thorn, poplar, sycamore, willow, salt cedar, cattail, etc. Water is visible from digging under these plants. At the foot of the mountain, where reeds grow, dig down in a green place, and it is often possible to dig underground water at a depth of 1 5 meters.

Look for places where the grass grows lush and green and dig down until water seeps into the pit dug. Observe wildlife tracks Keep an eye out for wildlife activity (especially in the morning and evening), where there are insects, flies, animals, birds, and there must be water nearby. Trace their footprints and often find groundwater sources.

Flocks of birds will hover over the water source. In the morning and evening, leave their cries to determine where they are located. Quails fly to the water source in the evening and leave early in the morning.

A flock of turtledoves flies to the water source in the morning and evening. You can also look for holes and dens of wild animals, as they are close to water sources for food. Look for terrain with water sources It is likely to find water sources in palms that are high on all sides and low in the middle, or in the dustpan-shaped areas that are high on three sides and low in the middle or on one side, as well as low-lying areas among the mountains.

Second, water sources may be found in dry riverbeds, especially in the riverbeds between two mountains and one ditch. You can choose to dig down at the lowest point on the outside of the bend of the river until you find wet sand. The damp sand on the surface indicates that it is a place where shallow wells can be dug, and the water can be seen by digging down from the low-lying area, and then down 0,8 1,8 meters.

If it remains wet, you can continue digging. Third, herders often have water sources near abandoned cattle and sheep pens that they use. Wherever there are wells, local herders are accustomed to use stones stacked on top of nearby hills or on higher ground as a sign to indicate that there are wells nearby.

Finding water When the desert is in distress, when the water runs out of food, it is better to find the water source than to sit and wait to die of thirst. In fact, some desert areas, especially the edge of the desert, can be found with saline water. If you are near a water source, stay there and be prepared to signal for help.

If you stay in a place where there is no water, try to find it. The search for water can be done as follows: Look for various traces in the desert - follow them to find water sources or habitats for people, and in special cases, several tracks will converge to lead you to a special settlement.

At the foot of the mountain, where reeds grow, choose a green place to dig down, and it is often possible to dig underground water below 1 5 meters. Look for places where the grass grows lush and green and dig down until water seeps into the pit dug. <>

Third, you can take the water by distillation. The desert is a place where the temperature difference between day and night is very large, you dig a deep pit in a relatively dry place, and then put the container at the bottom of the pit, spread a waterproof membrane on it, seal it with sand all around, put a stone on the top of the waterproof membrane, and after the temperature difference between morning and evening, it is very likely to get clean water. However, if relatively moist land cannot be found, this method fails.

Not only do you have to carry enough water before entering the desert, but you also have to follow the arrangements of the locals and don't move around on your own, otherwise the consequences of getting lost will be unimaginable.

Dig a sand pit in the sunny part of the desert, insert four wooden sticks into the pit, put the water cup in the middle, and then put the plastic paper on it, after the sun shines, absorb the steam in the air, and after half an hour, there will be water droplets attached to the plastic paper.

You can generally find water sources around plants that need water to survive in the desert, such as Rhizopus spp., white thorn, Poplar triangular, Sycamore tree, willow, salt cedar, cattail, etc. Water is visible from digging under these plants.

You can also pay attention to the tracks of the animals around you and follow the tracks to find the water source.

This can be achieved by identifying trace amounts of water vapor in the atmosphere. To find water sources and meadows in the desert, the roots of plants generally contain a certain amount of water. Or follow the camels.

The way to find water in the desert is as follows:

1. Pay attention to the herbivores in the desert, they want to drink water, and they are more familiar with the water source, you can observe their whereabouts, and follow their steps to find the water source.

2. If flies, bees, etc. are found in the desert, it means that they are not far from water, and if they are carnivores and small birds, they cannot be used as a reference, because they can go without drinking water for a long time.

3. If you see some weeds or mosses in the desert, it means that the place here is relatively humid, and digging along the damp place will also be possible to dig up groundwater.

It also rains occasionally in the desert, often stormy. The Sahara Desert once recorded 44 mm of precipitation in three hours. At this time, the normally dry river will quickly fill with water, and it is prone to flooding.

Although it rains less in the interior of the desert, the desert often feeds from rivers that flow from the nearby mountains. These rivers carry a lot of earth with them, and they run in the desert for a day or two before they dry up. There are only a few major rivers in the world that flow through deserts, such as the Nile in Egypt, the Yellow River in China, and the Colorado River in the United States.

If there is enough water, seasonal lakes will form in the desert, which are generally shallow and salty. Because the bottom of the lake is very flat, the wind will blow the lake dozens of square kilometers. When the lake dries up, a salt flat is left behind.

1. If you see traces of people passing by, you can look for them along the traces, and there will be a certain chance of finding a population gathering place, and if there is a place where the population gathers in the desert, there must be a water source nearby.

2. If you see some weeds or mosses in the desert, it means that the place here is relatively humid, and digging along the damp place may dig up groundwater.

3. In the evening or morning, if you see small animals or birds passing by, you can also track their whereabouts, and it is also possible to find a water source. If you see a flock of birds hovering above the desert, there is a high probability that there is water below the flock.

4. If there are camels around you in the desert, you can also ride a camel to find a water source, because camels are still very sensitive to water, and it is possible to find a water source while riding a camel.

5. If you are in the desert, carefully observe the terrain of the desert where you are currently located, if you see a low dustpan-shaped area or a high middle on all sides, you may find a water source in the low-lying land.

6. In the desert, there may also be a dry riverbed, you can dig at the riverbed between two mountains and a ditch or the lowest point outside the bend of the river, if you dig down and find wet sand, not far from the underground water source.
