A flat-plate two-dimensional groundwater hydrodynamic and water quality model device

Abstract

The invention relates to a flat two-dimensional groundwater hydrodynamic and water quality model device, which includes a water tank, a sand box and a water supply device. The water tank includes a pressure-bearing layer partition, which can flexibly adjust the internal hydraulic gradient of the model to simulate the situation of different pressure-bearing layers; the sandbox includes a support rod, a front panel, a rear panel and a bottom plate, which can observe the change of the internal hydraulic conditions of the model in real time and Take a water sample. The application of this device can better control the physical characteristics of the experimental medium, simulate the migration of pollutants in groundwater under complex flow conditions in various situations, provide efficient observation channels, and flexibly adjust the model through the assembly and disassembly of the model It can also provide external upgrade equipment for the model to improve the utilization rate of the model and reduce the cost.

Description

technical field [0001] The invention relates to a groundwater hydrodynamic simulation and pollutant migration test simulation device, in particular to a pollutant migration test in an aquifer medium under complex hydrogeological conditions. Background technique [0002] In recent years, with the rapid development of the economy, the groundwater body has been polluted to a certain extent, and the water resource environment has also been seriously threatened. The law of groundwater movement is extremely complex, and often has a series of characteristics such as large-scale space and long time. In laboratory experiments, it is often difficult to control the hydrological conditions, boundary conditions, recharge conditions and formation lithology in the model study area. In particular, when the study area is in the coastal area, the aquifer is strongly influenced by the ocean. On the one hand, the groundwater in the coastal area is subject to the interaction of submarine ground...
