Where is the well drilled for sufficient water?

Where do wells usually have sufficient water?

1. "It is most beneficial to find water in a dustpan." In the Tuoji land surrounded by mountains on three sides, the groundwater flows concentratedly to the Zuoji mouth, so wells are drilled near the Cuoji mouth, and the water output is more.

2. "There is a ditch between two mountains, and there is water flowing in the ditch rocks." There is a valley between the two mountains, and it is easy to find water sources in the rock formations on both sides of the valley.

3. "The two ditches intersect, and the spring water is surging." At the foot of the mountain mouth where the two gullies meet, there may be spring water flowing out. Wells are drilled here, and the water source is more reliable.

4. "The mouth of the mountain is opposite the mouth of the mountain, and there is good water under the mouth." The two mountain mouths are facing each other and the distance is similar. The terrain under the two mountain mouths is flat, and it is easy to drill wells at the locks.

5. "There is a lonely mountain between two mountains, and the water often does not dry up." If the rock formation at the bottom of the isolated mountain becomes an aquifer due to local variations in lithology, it can block the flow of groundwater, and if a well is drilled in the upper reaches of the isolated mountain, water can flow out.

6. "There is a mouth between two ditches, and there is spring water below." The mountains on both sides are longer, and there is a short mountain in the middle. At the mouth of the mountain in the middle, if there is a permeable layer above and an impermeable layer below, wells can be drilled in the lower slopes to produce good water.

7. "The mountains are low, and the wells and springs are digging a lot of water." The mountains are connected far away, dipping at one end, and groundwater can be found in aquifers at the proper topography of their dipping ends.

8. "When the mountain turns its head, there is water flow". The lower part of the mountain bay caused by the twisting of the mountain blocks the groundwater flowing along the mountain, enriches it in the aquifer, and provides water for drilling wells.

9. "Convex mountains are facing concave mountains, and good water is in the concave." The shape of one mountain protrudes toward the opposite side, and the shape of the other mountain is concave inward.

10. "There is a lot of water when a well is drilled out of a big mountain." A short mountain protrudes from the middle of the long mountain. Wells are drilled at the low place in the inclined direction of this mountain, and water can generally come out.

11. "Bay to bay, the water is not dry." The two mountain bays are facing each other. In the middle of the bay, waterlogging or good water plants appear, which is a manifestation of the backlog of water in the mountains. Wells are drilled here, and there are good springs.

12. "The two mountains meet, and there is a spring flowing underneath." Generally, there is no perennial running water between mountains, and floods may be discharged at the joints during the rainy season, and groundwater may be exposed as springs at the joints in the dry season.

13. "There are many pebbles on the floodplain, and the underground diving is like an underground river." Although the river has dried up in winter, there is submerged flow under the floodplain, which can be intercepted and stored, and wells can be dug for water.

14. Look for ancient river channels along the river. Although the ancient river channel is buried now, the aquifer is sandy gravel, and there is still phreatic flow, so it is a good place to drill wells
