    • The International Ground Water Modeling Center (IGWMC) is an internationally oriented information, education and research center for ground-water modeling. The International Ground Water Modeling Center (IGWMC) was established in 1978, In 1991, the IGWMC was relocated and became part of the Colorado School of Mines (CSM), Golden, Colorado. It is currently operated as a research center in CSM's Department of Geology and Geological Engineering. The mission of the International Ground Water Modeling Center is to stimulate the correct and efficient use of simulation models and related computer-based support technology in the management and protection of ground-water resources; train ground-water professionals by involving them in this endeavor; and facilitate communication and interaction of ground-water professionals on modeling issues. The site provides information about its software,publications, conference, news and link, etc.

    • 应用克里格法、支持向量回归法、核极限学习机法建立多相流模拟模型的替代模型,并应用集对分析法建立组合替代模型,通过将多种替代模型进行对比,分析不同替代模型在地下水DNAPLs污染修复多相流模拟问题中的适用性.结果表明,3种单一替代模型中,克里格模型的精度最高,其次是核极限学习机模型,最后是支持向量回归模型;应用集对分析原理建立集对权组合替代模型,与单一替代模型相比,其模拟模型的逼近精度更高,且提升效果十分显著,平均残差和平均相对误差分别为0.4009%和0.5373%;集对权组合替代模型运行一次仅需1.5s,选择组合替代模型代替多相流模拟模型进行地下水DNAPLs污染的修复方案优选分析,能够大幅减小模拟-优化过程的计算负荷,并保持较高的计算精度.
