环境水力学反问题研究进展

Advance in inverse problems of environmental hydraulics

反问题广泛存在于环境水力学的各个研究领域,通过环境水力学反问题研究可以实现对水流及伴随水流系统的污染物质迁移、输运过程的识别和控制,促进水资源的可持续利用。近年来,环境水力学反问题研究内容逐渐丰富,其重要性日渐突出。基于反问题理念阐述了环境水力学反问题的内涵,从不同的角度对环境水力学反问题进行了分类,强调了环境水力学反问题研究的重要意义。从参数反问题、源项反问题、边界条件反问题、初始条件反问题和形状反问题5个方面分析评述了环境水力学反问题的研究现状和研究成果。在此基础上,讨论了研究现状存在的问题并对该领域未来研究方向进行了展望。

The inverse problems exist widely in the field of the environmental hydraulics. The flow and pollutants transporta- tion, coupled with flow, can be identified and controlled by the study of the environmental hydraulics, which benefits the con- tinual utilization of water resources. Based on the idea of the inverse problem, the connotation of the inverse problems of the environmental hydraulics is expounded. The inverse problems of the environmental hydraulics are sorted according to the vari- ous points of view. And its importance in research is emphasized. In this paper, the present study methods and results are an- alyzed from the aspects of the inverse problems on the parameter, source, boundary condition, initial condition and shape in the environmental hydraulics. Some unresolved issues and future research perspectives are also addressed.
