The distribution of the median 0ø, Mdø, of the fluvial deposits of main, rivers in Kanto plain is report_??_d in this article. The tractive fore of the current in moving bed-material, T, is given by
T=WRI
where R is hydraulic radius and I is gradient.
But the hydraulic radius changes in very small scale comparing to the gradient, therefore the mean grain size of the deposits in this distric is mainly, deterniined by gradient.
