The experimental scheme of the three selected well flow experimental modules is as follows: only one-hole pumping well has no observation hole scheme; a water pumping well and an observation hole are used for prevention; one-eye pumping well, two-eye observation well scheme.
Downward osmosis experimental principle-downward osmosis theory:
the soil moisture infiltration process can be divided into infiltration, seepage and infiltration stages of 3 according to different moisture stress, and the soil moisture content, the moisture existence form and the like are different along with the different soil moisture infiltration stages.
In the infiltration stage of the infiltration process, the soil generates stronger water absorption capacity by combining water, and the water content is influenced by the outside to the greatest extent; when the water content is obviously increased by receiving exogenous replenishment, the soil is combined with the outer layer of the water belt, hole angle capillary water is increased, and the combined water and the hole angle capillary water exist; when the soil moisture reaches the maximum molecular water holding capacity, a seepage stage is started, and the moisture continuously infiltrates downwards along with downward expansion of the capillary suspension belt; when the water content of the soil is close to or exceeds the maximum water content limit of the pore angle capillary water, the soil water enters the suspension capillary water range; when the soil moisture reaches a saturated state, the infiltration water is only acted by gravity and enters the infiltration stage, so that the water transmission effect is strongest, and the capillary water saturation belt is supported to be tightly connected.
Well flow experimental principle-steady motion theory of groundwater to a complete well:
the underground water complete well means that the well penetrates through the whole aquifer, and the filter is installed on the thickness of the whole aquifer and can fully feed water. The underground water movement theory of the complete well and the incomplete well is different from that of the underground water movement theory of the incomplete well, and the experiment is only aimed at the complete well.
Assuming a circular island-shaped aquifer with radius R, a pumping well is drilled in the center, and the water head H0 at the island boundary is fixed and unchanged, which is the same as the initial underground water head before pumping. Pumping water in the well, lowering the water level of the well, and flowing the surrounding water into the well to form a dropping funnel. As pumping continues, the drop funnel expands to supply the well's volume of water, and the groundwater movement is unstable during this process. When the funnel is expanded to the boundary of the fixed water head of the island, the underground water is supplied around the island until the supply quantity is equal to the water pumping quantity, and the movement of the underground water reaches a stable state. The experiment only aims at steady state to develop relevant research.
Groundwater aquifers are classified into diving aquifers and confined aquifers according to whether they are confined or not, whichever aquifer is difficult to see, such as the ideal circular island aquifer described above, typically bounded aquifers with lateral supply, or infinite aquifers. When the water is pumped for a long time by the bounded aquifer, the movement of the groundwater is stable when the replenishment amount is equal to the pumping amount, and the steady flow of the infinite aquifer is not strictly possible, but a quasi-steady state can be generated after the water is pumped for a quite long time.

It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
