基于和声搜索算法的地下水污染源与未知含水层参数的同步反演研究
Simultaneous identification of groundwater contaminant source and aquifer parameters by harmony search algorithm
摘要
Abstract
Both groundwater contaminant source identification and aquifer parameter identification belong to groundwater inverse problems. In absence of prior information about aquifer parameter, simultaneous identification contaminant source and aquifer parameters are needed on the basis of the obtained monitoring data. In the simultaneous identification problems, the location and strength of contaminant sources, the unknown aquifer parameters are taken as the decision variables. In this paper, the framework of the simultaneous identification model, including simulation model and optimization model, is firstly introduced, and then an improved harmony search algorithm is proposed on the basis of several existing improved harmony search algorithms and combined with the simuhaneous identification model. Finally, the simultaneous identification model, with improved harmony search algorithm, is applied to case study. The case studies indicate that the improved harmony search algorithm is stable and efficient with relative fast convergence speed and the high robustness, and applicable to groundwater contaminant source identification and aquifer parameter identification.关键词
