Abstract
An annular flume has been constructed in order to estimate the erosion rate of fine cohesive sediments. Under an uniform bed condition, some erosion tests for Kaolinite sediments have been conducted to examine the performance of the flume and to check the validity of experimental method and results. In this study, the critical shear stress for erosion and the erosion rate coefficient are estimated and compared with the existing measurements. It is concluded that the performance of the annular flume is good enough to conduct erosion tests and the experimental method and results are valid.
