摘要：Low-frequency waves generated oil a submerged curvilinear sill by bichromatic wave groups with and without an opposing current are studied experimentally in a laboratory flume. The second-order wave maker theory is used to generate the primary waves and the spurious long waves were significantly suppressed. The generation of harmonics, wave blocking of the short waves and especially the penetration of long waves through the blocking point have been observed. The evolution of long waves before and after the blocking point is described in detail.
