tidal scour

基本解释

Because the pipeline diameter in platform is one third of that in tidal channel, so the limit scour length is less.
而平台区由于设计管径仅为潮汐通道区的三分之一，其极限冲刷长度远小于潮汐通道区。
There are many sluices built in tidal estuary, Zhejiang province, in which an important problem is scour protection for soft foundation of sluice downstream.
浙江省的感潮河口水闸众多，其闸下软基防冲是众人最关心的问题。
Therefore, the seabed soil failure due to the tidal current scour in the cable route area may occur to affect the safety of submarine cable buried in the seabed soil.
路由区海底土会因潮流冲刷作用而发生失稳破坏，影响埋设在海底土中海缆的安全。
