How to find
With sensitive hearing organs, pay more attention to whether there are sounds of mountain streams or waterfalls in the foot, mountain, cliffs, basins, and valleys, and whether there are frogs and water birds. If you can hear these sounds, it means that you are not far from the place where you have water, and you can prove that these water sources are flowing and can be directly consumed. However, special attention should be paid not to use the sound of wind blowing leaves as a sound of running water. Sniff your nose and smell as much as possible, or the smell of dirt and water that comes from the wind. Then look for the source of water in the direction of the odor. Of course, this must have accumulated some experience.
Observing with rich experience and knowledge. Water can also be found by observing animals, plants, weather, climate and geography. According to the topography (geographical environment), determine the level of groundwater level. At the foot of the mountain, there is often groundwater, low-lying areas, rainwater concentrated areas, and downstream of reservoirs are all high groundwater levels. In addition, under the dry river bed. At the lowest point on the outside of the turn of the river, water can be obtained by digging a few meters down. However, there are many muds that need to be purified before they can be drunk.
ground
For example, in the hot summer months, the ground is always very humid. Under the weather conditions, the groundwater level is high in the ground where the sun is not drying, and the groundwater level is higher in the ground; in the autumn, the water vapor rises on the surface, and it often appears like yarn in the morning. In the mist, the dew is heavy at night and the ground is wet, indicating that the groundwater level is high and the amount of water is sufficient; in the cold winter, when there is white frost at the surface of the ground, the groundwater level is also relatively high; the place where the spring thaws early and the winter freeze is late The groundwater level is high both in the place and in places where the snow melts quickly after snowfall.
According to the growth conditions of the plants , the places where the water source grows with the typha, salix, malaria, golden needles (also known as yellow flowers), and mustard are used. The water level is relatively high and the quality of the water is good. The areas where the grey vegetables, garcinia, and shaliwang grow are found. There is also groundwater, but the water quality is not good, there is bitter or astringent, or with rust; early spring. When other branches are set to germinate, there is a single branch that has germinated and there is groundwater; when it enters the fall, the other trees in the same place have already turned yellow, and the only one leaf is not yellow, and there is groundwater; in addition, it is also like a triangle. Ye Yang, phoenix, willow, salt cedar, these plants only grow in places where there is water, below them will be able to dig out the groundwater.
animal
In the summer, mosquitoes gather and there is water in places where they fly into a cylindrical shape. There are also water in places where frogs, big ants and snails live. In addition, there are water sources and groundwater levels where the swallows fly over and where the mud nests. Higher place. In addition, flying to the water in the evening and flying back in the early morning, the magpies fly to the water sooner or later. These are also the basis for judging the source of water. I
the weather
Where there are rainbows in the sky, there must be rain. Under the cumulonimbus clouds with lightning and lightning, there is rain or hail. There are water sources in valleys where there are always thick fogs; collecting dew can also ease the urgent need.
plant
In the jungles of the south, there are wild plantains, also known as the cannas. The core of this plant has a large amount of water, so long as it is quickly cut off from the bottom with a knife, a clean liquid will drip from the stem, and the young core of the wild plantain can also be eaten. . If you can find vines such as kudzu vines, grape vines, kiwi vines, and quince vines, you can also get drinking water from them. In addition, when the spring trees are to be germinated, drinking water can be obtained from the trunks and branches of arbors such as pagoda trees and hawthorn trees. Note: Do not drink the vines with the emulsion or the sap of the irrigation and trees. It is poisonous. In addition, drinking water can be obtained from the algae, cactus and its fruit. Tip: Drinking “water†obtained from plants is prone to deterioration. It is best to drink immediately and do not store it for a long time.
The above water intake method is effective when there is a shortage of water in the field. However, simply relying on the above method to find water is not a long-term solution, and it is very complicated and hard. Limited to a few people (3-7) and a short time (3 to 5 days). Not suitable for many people or too long. In terms of safety, I hope that it is best for friends not to stay away from the water for a day or two, or to single-handedly walk through the jungle.
When you find a source of water when you are extremely tired and thirsty, it is advisable not to drink it immediately. The water should be purified and disinfected as necessary in order to avoid poisoning or disease caused by drinking water. Â
Purification treatment
In general, except for spring water and well water (underground deep wells) that can be directly consumed, whether it is river water, lake water, stream water, snow water, rainwater, dew water, or water obtained through infiltration, filtration, and sedimentation, it is best to Disinfect before drinking. So how do you do disinfection? Methods as below:
1. Put the water purification tablets into a water container, stir and shake, let stand for a few minutes, then you can drink, can be stored in the pot for storage. Under normal circumstances, a piece of water tablets can sterilize 1 liter of water, if you encounter water sterilized tablets that can be used for sterilizing. At present, the army has adopted this method to sterilize water in the wild. Wild life (6 photos).
2. If there are no clean water tablets, water can be disinfected with medical iodine bottles that are carried around instead of water purification tablets. In purified water, 3 to 4 drops of iodine per liter of water droplets. If the water quality is turbid, the patient's iodine in each liter of water is doubled. After stirring and shaking, the standing time should also be longer. After 20 to 30 minutes, it can be drunk or ready for use.
3. The use of chlorite, bleach, can also act as a disinfectant. In the purified water, 3 drops or 4 drops of bleach per liter, and the turbidity of the water is doubled. Shake well and stand for 30 minutes. Only the taste of some bleach in the water, be careful not to drink the precipitated turbidity together.
4. If none of the above disinfecting drugs occurs, it is sensible to carry the vinegar that is used in picnics (white vinegar is also OK) and it is also possible to disinfect the water. In the purified water, pour some vinegar, stir well and let it stand for 30 minutes before drinking. It's just the acidity of some vinegar in the water.
5. At altitudes not too high (above 3,000 meters above sea level) and in the case of a fire, it is a good idea to sterilize the water by boiling for 5 minutes.
6. If the water you are looking for is salty, cook with pepper grass and water. Although this can not remove the original salty, it can prevent abdominal pain, bloating, and diarrhea. If there is heavy metal salt or toxic minerals in the water, use thick tea and boiled water. Do not drink the last sediment. At present, there is a drinking water purification straw, which is very practical in the field. It is shaped like a thick pen. The water it purifies is non-yin, non-toxic, odorless, without any impurities, and can be drunk without boiling. It is very light.
Another thing to be reminded is that, in the case of water shortages, it is necessary to arrange drinking water rationally and not to guzzle for a moment of thirst. In addition, in the field work or adventure, drinking water should also pay attention to science. If you drink enough at a time, the body will excrete excess water after absorption, which will waste a lot of water in vain. If you drink water, drink only one or two at a time, and then slowly swallow in the mouth. After a while, when you feel thirsty, take a sip and slowly inhale. This way, you can make the body drink. The water is fully absorbed and it can solve the dryness of the tongue and throat. A standard kettle (9 to 11 liters) of water, using the right drinking method, can make an individual soldier adhere to 6-8 hours or even longer.
