Channels draining burned areas have zones of erosion and zones of deposition. This deposition occurred downstream from the erosional zone shown in the previous photo. The peeled bark indicates the highest level of water and debris during a flash flood. Sediment is coarse sand and gravel. The view is downstream and the blue backpack is about 1 meter tall.

Animation comparing rain falling onto two volumes of soil: one that is sandly loam and one that is clay loam. Blue raindrops fall uniformly over both boxes and begin to infiltrate the soil surfaces. The rain infiltrates the sandy loam soil volume more deeply, but within a relatively narrow vertical channel. The rain infiltrates the clay loam volume in a shallower, more horizontally spread out pattern
