Description

Technical Field

[0001] The present invention belongs to the technical field of three-dimensional geological modeling, and in particular relates to a real-time three-dimensional geological modeling system and method based on groundwater dynamics. Background Art

[0002] Groundwater dynamics refers to the changes in groundwater level, flow velocity, flow direction and water quality elements over time. It is a comprehensive reflection of the groundwater system's response to natural and human factors, and is crucial to understanding the distribution, migration and storage of groundwater resources. Changes in groundwater dynamics directly affect the interaction between surface water and groundwater, the recharge and discharge process of groundwater, and the development and utilization strategy of groundwater resources. Monitoring groundwater dynamics has multiple meanings. First, it helps to promptly detect abnormal changes in groundwater levels and provide early warning information for flood control, drought relief and water resources management. Secondly, by monitoring groundwater flow velocity and direction, the flow path of groundwater can be revealed, providing a basis for tracking and controlling groundwater pollution. In addition, groundwater dynamic monitoring can also help evaluate the sustainable utilization potential of groundwater resources and provide a scientific basis for regional water resources planning and management.

[0003] Traditional groundwater dynamic monitoring mainly relies on manual observation and water level gauges. Observation wells are the main way to obtain groundwater level data. Regular or irregular manual measurements are used to record changes in groundwater levels. At the same time, flow rate and direction of groundwater can be measured using flowmeters. These data are usually recorded in paper or spreadsheets for subsequent analysis and processing. In terms of analysis, traditional groundwater dynamic analysis is mainly based on statistical methods and hydrological models. Through statistical analysis of historical data, seasonal and interannual changes in groundwater levels can be revealed. At the same time, hydrological models can be used to simulate the flow process of groundwater and predict future trends in groundwater level changes. However, traditional groundwater dynamic monitoring and analysis methods have many shortcomings. First, manual observation is limited by observation frequency and accuracy, and it is difficult to capture rapid changes in groundwater levels. Second, the data recording and processing process is cumbersome, error-prone and inefficient. In addition, traditional hydrological models are often based on simplified assumptions and conditions, and it is difficult to accurately reflect the complexity and nonlinear characteristics of groundwater systems. These limitations lead to the fact that the results of traditional groundwater dynamic monitoring and analysis are often not accurate and timely, and it is difficult to meet the needs of modern water resources management and environmental protection. Therefore, there is an urgent need to develop a real-time three-dimensional geological modeling system based on groundwater dynamics to provide timely and accurate information support for water resources management and environmental protection.
