INFILTRATION RATES OF UN DISTURBED AND DISTURBED

MOUNT ST HELENS TEPHRA DEPOSITS1/

by

Allen J. Fiksdal

The May 18 , 1980 eruption of Mount St. Helens wreaked havoc on the forested terrain north and west of the mountain. The tephra deposits resulting from the blast and eruption covered the area's forested slopes with up to a meter of ash in some places. The ash restricted infiltration of rainfall into the slopes, causing rapid runoff and erosion problems throughout the area. In the Shultz Creek drainage, 20 km from the mountain's center, ash deposits ranged in depth from 3 cm to 30 cm , and often the ash Erosion of clearcut after one winter; extensive rill network has developed. depths change over a few meters distance. The stratigraphy of the tephra deposits in the Shultz Average thicknesses of these deposits are ap­ Creek area is basically two distinct layers: proximately 14 cm of blast material and 6 cm of coarse sand to sand- sized rock fragments from airfall ash. the initial lateral blast underlie a silty airfall ash. Through late Spring of 1980, saturation by rainfall and subsequent drying throughout the summer resulted in the compacting of the silt layer of ash. This compaction led to very low infiltration rates. Some early tests of infiltration rates by the U.S. Geological Survey and the Washington Department of Natural Resources, Division of Geology and Earth Resources, found infiltration to average less than about 5 mm per hour. In the summer of 1980, programs were set up to measure erosion in the blast area of

In the late summer, salvage of some of the downed timber prompted interest in measur­ ing erosion on the sites where timber had been removed and the layers of ash disturbed. Preliminary results this spring revealed erosion rates were highest in areas of clearcuts, lower in areas of timber blow down, and lowest in areas where the blowdown timber had been removed. These results indicated that timber removal reduced erosion on the sites measured.

Same area after timber was removed. Note large amount of organic debris left after timber removal.

Of interest still was what the actual in­ filtration capacity of these timber removal sites were. Interest in infiltration rates increased with the decision by the Washington State Department of Natural Resources to scarify ( disrupt the stratigraphy by mixing the tephra layers with a bulldozer) some of their clearcut land to decrease erosion. Experimentation using one square meter plots were devised to measure infiltration rates on different areas in the Shultz Creek drainage. Sites on undisturbed ash in clearcuts, on areas Ash covered timber in Shultz Creek area. where timber had been removed, and on areas Ash loss by erosion• that had been scarified were selected. The tests Clearcut Down timber Timber removed entailed putting a controlled simulated rainfall 3 3 420 meters /hectar 260 meters /hectar 90 meters3 /hectar on a plot and measuring runoff over time.
