摘要
弯曲河段水流运动与河床变形规律广泛应用于河流治理、引水灌溉、护岸工程等诸多领域.首先,对弯道水流运动及河床变形一般特性做了简要概括;其次,对弯道水流运动、河床冲淤变化及河岸冲刷方面的数值模拟研究成果进行了简要评述;最后,指出了目前弯道水流运动及河床变形数值模拟中存在的主要问题,探讨了该研究领域的发展趋势.
Studies on the water flow and river-bed deformation in curved channels have wide applications in river improvement,diversion for irrigation,bank protection work,etc.Firstly,the general characters of curved river flow and river-bed deformation were summarized.Secondly,numerical studies for curved river flow,bed scouring and deposition,and bank erosion were reviewed and analyzed.Finally,the future development in numerical simulation of curved river flow and bed deformation was prospected.The result could provide guidance for further studies on the water flow and river-bed deformation in curved rivers.
