A dynamic simulation method for recharging groundwater with surface water

Abstract

The invention discloses a dynamic simulation method for recharging groundwater with surface water, comprising the following steps: assembling equipment: connecting a surface water input unit, a groundwater input unit, a discharge unit, a flow monitoring unit, a river simulation unit, a vadose zone simulation unit and a Aquifer Modeling Unit; Groundwater Flow Field Modeling: Controls the connection between the groundwater input unit and the aquifer modelling unit, and the connection between the discharge unit and the aquifer modelling unit to obtain a stable subsurface flow field; Infiltration modelling: Controls the surface water input unit The connection with the river simulation unit and the connection between the discharge unit and the river simulation unit, and obtain the infiltration amount and effective replenishment amount of the vadose zone; infiltration monitoring: the flow monitoring unit monitors the internal and external conditions of the vadose zone simulation unit. The aquifer simulates the moisture content or liquid level in the unit; and realizes dynamic and three-dimensional monitoring of the influence of infiltration moisture on groundwater flow under different river runoff conditions.

Description

technical field [0001] The invention relates to the technical field of experimental simulation, in particular to a dynamic simulation method for replenishing groundwater with surface water. Background technique [0002] Groundwater is an important water resource in my country. Among the 657 cities in the country, more than 400 use groundwater as a source of drinking water. Taking the Beijing-Tianjin-Hebei region as an example, groundwater accounts for more than 70% of drinking water. However, due to the long-term overexploitation of groundwater in some areas, a series of environmental problems such as groundwater quality deterioration and land subsidence have arisen. [0003] Groundwater recharge is an effective measure to systematically solve the security of water supply, restore the exploitation capacity of water source, and improve the groundwater environment. At present, with the improvement of water supply, rainwater and flood utilization rate and regeneration of wate...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is that due to the lack of corresponding surface water recharge groundwater simulation method, it is impossible to realize dynamic and three-dimensional monitoring of the influence of infiltration water on groundwater volume under different runoff conditions of rivers.
