Flat plate tracing simulating device system and simulating method for salt water intrusion under tidal action

Abstract

The invention discloses a flat plate tracing simulating device system for salt water intrusion under tidal action. The flat plate tracing simulating device system comprises a flat plate water channel, a tidal wave generator, a salt water reservoir, a fresh water tank and a salt water tank, wherein the flat plate water channel is provided with a fresh water area, a sediment area and a salt water area along the length direction; the sediment area is filled with sediment and provided with 5-6 sample discharging-taking holes; the fresh water area, the sediment area and the salt water area are spaced by a filtering net and a water permeable inserting plate respectively; the tidal wave generator is arranged between the salt water area of the flat plate channel and the salt water reservoir; the fresh water tank is connected with the fresh water area of the flat plate water channel through a flowrate regulating device and used for injecting fresh water to the fresh water area; and the salt water tank is connected with the salt water area of the flat plate water channel through another flowrate regulating device and is used for injecting salt water to the salt water area. The full process of salt water intrusion under tidal action can be visually viewed through the device, so that the purpose of deeply exploring the mechanism of sea water intrusion is achieved.

Description

technical field [0001] The invention relates to an experimental simulation device, in particular to a flat plate tracer simulation device system for salt water intrusion under the action of tides, and also relates to a flat plate tracer simulation method for salt water intrusion under the action of tides. Background technique [0002] Saltwater intrusion is an important problem facing the development of industry and agriculture in coastal cities, especially in northern regions, where excessive pumping of groundwater has caused large areas of saltwater intrusion, seriously affecting the lives of local people and economic development. At the same time, salt water intrusion also has a significant impact on the ecological environment of coastal areas, causing large areas of land salinization, and the original freshwater biome is gradually transitioning to saline biome. With the further aggravation of salt water intrusion, the social and environmental problems it caused have beco...

AI Technical Summary

Problems solved by technology

Due to the simplification of the research problem, most experimental models do not consider the tidal effect, but the research proves that the tidal effect has an important influence on the simulation results, so the reference value of these experimental simulation results is greatly reduced; because the NaCl dissolution and dilution process cannot be distinguished by the naked eye, the Probe monitoring will not only greatly increase the cost of the experiment, but also the operability of the experiment is not high, and there are difficulties in the visualization of the experiment process

Due to many problems, there are still few experimental studies using indoor models to simulate saltwater intrusion, and only numerical models with limitations cannot achieve the purpose of in-depth exploration of seawater intrusion mechanisms.
