The turbulent velocity components (u, v) at eight points in a plane perpendicular to the mean flow have been sampled and recorded simultaneously by a A/D converter. The quasi-instantaneous 3D images of coherent structures in the flood flow were reconstructed from these data by using a new method of data analysis. These structures detected near the river bed are low-velocity lumps of fluid and generate intermittently peaks of the high positive Reynolds stress. The high concentration of the suspend load in the flood flow may be explained by these structures. Near water surface, the coherent structure has also been found and they generated small-scale boils.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
