REPORT:
Post-Eruption Changes in Channel Geometry of Streams in the Toutle River Drainage Basin, 1980-82, Mount St. Helens, Washington

-- D.F. Meyer, K.M. Nolan, and J.E. Dodge, 1986, Post-Eruption Changes in Channel Geometry of Streams in the Toutle River Drainage Basin, 1980-82, Mount St. Helens, Washington: USGS Open-File Report 85-412

The May 18, 1980, eruption of Mount St. Helens, Washington, generated a debris avalanche, lateral blast, lahars, and tephra deposits that altered mainstem and tributary channels within the Toutle River drainage basin. Channel cross sections were monumented and surveyed on North Fork Toutle River and its tributaries, on South Fork Toutle River, on Green River, and on Toutle River in 1980 and 1981. This report presents channel cross-section profiles constructed from the survey data collected during water years 1980 through 1982. -- Meyer, et.al., 1986
