Flow resistance data set and R code

This dataset and R program accompany a paper by R. Ferguson and A. Recking, submitted to Water Resources Research and titled 'Flow resistance and hydraulic geometry in gravel- and boulder-bed rivers' Important note: if the R program does not start, check that dataset.csv is in UTF8 format.本数据集与R程序配套发布，用于支持R·弗格森（R. Ferguson）与A·雷金（A. Recking）投稿至《Water Resources Research（水资源研究）》的学术论文，该论文题为《砾石与漂石床河流的水流阻力与水力几何形态》。 重要提示：若R程序无法正常启动，请确认dataset.csv文件采用UTF8编码格式。
