✦ Synopsis

Detailed measurements have been taken for the longitudinal turbulent intensities of flow in a gravel-bed flume. The experimental results indicate that the distribution of turbulent intensity greatly depends on the relative roughness. In comparison with the smooth-bed results, the roughness makes the flow turbulence become well-distributed, especially in the region near the bed and in the case of smaller H/K s values. In addition, the cross sectional average of turbulent intensity is also discussed in this paper, and the results show that the roughness makes flow turbulence much more intense.

## Abstract The vertical distribution of invertebrates in bed sediments was studied in a gravel stream in the hercynian region of Central Europe, using freeze‐cores to the depth of 70 cm at two sites with different flow conditions, taken on five occasions. About 78% of invertebrates were concentrat
