摘要
河流泥沙学科是一门综合性的基础技术科学,它是研究泥沙在水体中的输移、冲刷和淤积的规律,是水利学科的理论基础之一,包括泥沙运动力学、河床演变学、工程泥沙、航道与港口治理、高含沙水流与泥石流等多方面的内容。本文在查阅浏览大量研究资料基础上,着重从泥沙运动、河床演变、水库泥沙和数值模拟技术等几个方面对泥沙学科的历史进程、重要成果和发展动态进行了跟踪,对比分析了国内外研究水平,提出了今后发展的新方向和值得关注的议题,对我国河流泥沙在国际上发挥更大的作用具有参考意义。
The river sediment discipline is a comprehensive technical science, which studies the rules of movement, erosion and deposition of sediment in flows, covering sediment transport mechanics, fluvial river morphology, engineering sediment, regulation of navigation channel and harbor, hyper-eoncentrated flows, debris flow and so on. On the basis of browsing massive research literatures published at home and abroad, the authors carried out a tracking investigation on the sediment diseipline＇s historic evolution, major achievements as well as the development trend, with focus being laid on sediment movement, fluvial processes, reservoir sedimentation and numerical simulation technology. After analyzing and comparing the domestic and foreign researches, the authors put forward some proposals on development direction and issues worth paying more attention to.
