of lobe, based on fabric-morphometry relationships allowing the identification of different flow dynamics. In Carrara marble basins, the anomalous frequency with which debris flows tend to be triggered by medium-intensity rainstorms is due to the recent
A small catchment has been monitored in the high Gallego river basin (Central Spanish Pyrenees). The results show the great importance of autumn and occasional summer rainstorms for the sediment output. Sediment transport is negligible in winter
and adds little to the total volume during spring. Moreover, during the snowmelt, sediments are finer than those produced by rainstorms due to the hydrologic conditions and the different sediment sources.

An intense rainstorm affecting steep pasture-covered mudstone hill country in the North Island of New Zealand triggered many hundreds of shallow, rapid earthflows. Thirty of these and their associated site and soil conditions were investigated

A high-intensity rainstorm focused above Slide Canyon in North Ogden, Utah, during September 1991. This storm exceeded all previous records for the state and resulted in a debris flow that discharged onto an existing fan and into a residential
On July 18-21, 1996, a severe rainstorm caused widespread flooding along the north shore of the St. Lawrence River. At the Lake Ha!Ha! reservoir, inadequate available capacity to spill during the storm at the outlet dam resulted in the overtopping

these four rainstorms. A sub-objective was to determine if sediment had been eroded or deposited in the channel before the studied events in order to determine if any of the sediment discharge consisted of re-suspended material.
Hortonian runoff was measured in the laboratory from uniform slopes of lengths of 1.5, 3.0, and 6.0 m for steady, high-intensity rainstorms with durations of 1.0 to 7.5 min. A clear reduction in runoff per unit slope length was found as slope
