Up till now, local scour depth estimation in the nearshore architectures are assumed that whenever the seabed is flat, which not considered the common bed form: sand waves.
迄今，近岸水域建构筑物的局部冲刷深度的估算均假定局部冲刷前后为平床，没有考虑常见、广布的近岸沙波底形。
The variations of the local scour equilibrium depth with the parameters of the jet, such as jet exit height, width, velocity and sediments characteristics, were observed in the experiments.
实验观测了射流局部达到冲刷平衡时，最大冲刷深度随射流喷口高度、喷口宽度、喷口流速、横流流速及泥沙特性变化的规律。
Finally, we obtained distribution of the maximum depth of local scour under each experimental group by analysing and comparing the maximum depth data of local scour maximum.
最后，通过分析对比局部最大冲刷深度资料，得出各试验组次局部最大冲刷深度的分布规律。
Local scour on bridge pier caused by the sand movement is based on turbulence, understanding the turbulence characteristics in-depth can better raise awareness of local scour on bridge piers.
引起桥墩局部冲刷的泥沙运动是以水流脉动为基础的，只有深入地了解水流的脉动特性，才能更好地提高对桥墩局部冲刷的认识。
