Water and sediment discharge has been measured in a 283m2 catchment at Mount Unzen on a slope composed of recently deposited pyroclastic-flow debris. Measurements began in July, 1996, one year after cessation of eruptive activity. Vegetation on these deposits has recovered rapidly, primarily because the slope has been aerially seeded twice. Revegetation has reduced sediment discharge substantially, but has had little effect on storm runoff response. Analysis suggests that the decrease in sediment discharge results from reduced soil-surface erodibility, and that the limited effect of revegetation on stormflow runoff is explained by an immaturely developed root network and by insufficient soil crust formation.
