Abstract

The invention discloses a method for simulating the unsteady flow of lakes and groundwater, which describes the lake water balance process in detail, effectively reduces the dependence of the lake's spatial discretization on the subdivision of the groundwater grid system, and adopts an algorithm for tilting the bottom of the lake To solve the problem of continuity of lake-groundwater interaction boundary conditions, on the one hand, without reducing the discretization accuracy of lake space, it can reduce unnecessary vertical subdivision layers of groundwater aquifers, thereby effectively reducing the workload of simulation calculations. The convenience of application is greatly enhanced. On the other hand, it also effectively avoids the numerical oscillation problem caused by the large number of vertical subdivision layers in the simulation process, and improves the convergence stability of simulation calculation. Compared with the existing lake-groundwater interaction simulation method, the present invention has significant advantages in application convenience and calculation stability, and can be widely used in quantitative analytical research on lake-groundwater interaction.

Description

technical field [0001] The invention belongs to the technical field of groundwater numerical simulation, and in particular relates to the design of a simulation method for unsteady flow interaction between lakes and groundwater. Background technique [0002] When lakes and surface aquifers have a direct hydraulic relationship, there can be significant impacts on the lake and groundwater systems, so a technique was developed to quantify the interaction between lakes and groundwater to assess the impact of changes in equilibrium conditions on one side on the other. It is of great significance to regional water resource management. Unlike other surface water bodies such as reservoirs, the water level of a lake is not a definite value, but is related to its own water balance process, which is difficult to assess. At present, the methods for analyzing the interaction between lakes and groundwater mainly include experimental methods and model simulation methods. However, compare...
