Rainfall intensities of 45, 100, and 150 mm/hr with systematically varied kinetic energies were applied to a saturated noncohesive, sandy bed 3 m long and set at slopes of 0.5 and 5%. Detailed size analyses of solids discharged showed that the 4-mm fraction behaved as a lag gravel. The sedimentary properties of bed deposits also reflected the differentiation of various size fraction and minerals in the original mixture. The effects ...
