Embodiment Construction

[0035] 1. The present invention is used to solve the concrete steps in the multi-objective management problem of groundwater remediation as follows:

[0036] Step 1 establishes a simulation model to describe the temporal and spatial distribution of groundwater head and solute concentration in the remediation site. The groundwater flow model can be solved by the three-dimensional finite difference program MODFLOW developed by the US Geological Survey, while the solute transport model is solved based on the water head and velocity field solved by MODFLOW, using the modular three-dimensional solute transport program MT3DMS developed by Zheng Chunmiao. . The initial conditions and boundary conditions described in the water flow model and the solute transport model should be consistent with the actual site conditions, and the finally established simulation model is the corrected and tested water flow model and solute transport model.

[0037] Step 2 Determine the management object...

Abstract

The invention discloses a multi-objective groundwater remediation optimization method. The individual fitness function value archiving strategy, the Pareto dominance concept and a niche fitness sharing method are combined with tabu search (TS) to systematically form a new multi-objective optimization method. The method integrates the advantages of various optimization technology and is high in computing efficiency and strong in global search capability. Compared with the similar methods, the method of the invention mainly avoids repeated search in the optimization process and improves the diversity and the global property of seed solutions. The technology is coupled with the groundwater flow program (MODFLOW) and the solute transport program (MT3DMS) and has strong applicability to solving the multi-objective management model for groundwater pollution control.

Description

technical field [0001] The invention relates to the fields of hydrology and water resources, in particular to a multi-objective optimization method for groundwater restoration. Background technique [0002] In the optimal management system of groundwater pollution remediation, multiple conflicting management objectives are often involved. These objectives have some characteristics, including the incommensurability of the measurement units of each objective, and the contradiction between each objective function, which makes the multi-objective The solution to the optimization problem is not unique. The task of multi-objective management is to weigh the advantages and disadvantages of each objective and seek a compromise solution that meets the interests of each objective. [0003] Simulation-optimization model is the most effective method to solve the management of groundwater pollution remediation system, and it is also the most widely used solution tool. The simulation mod...
