Sediment routing in a small watershed in the blast zone at Mount St. Helens, Washington

Creator:

Smith, Richard D. (Richard Dean), 1950-

Abstract:

A descriptive model of the routing of sediment that was delivered to the study area by the 1980 eruptions of Mount St. Helens has been developed. On hillslopes this sediment was distributed among three major storage compartments: 1) the tephra profile, 2) primary storage, and 3) secondary storage. The most...

Streamflow and bedload transport in an obstruction-affected, gravel-bed stream

Creator:

Smith, Richard D. (Richard Dean), 1950-

Abstract:

The mechanisms of pool maintenance were investigated in a small (width = 10 m, drainage area = 18 km2), gravel-bed stream where pools are commonly associated with large, in-channel obstructions. Measurements of boundary shear stress, scour and fill of the stream bed, and bedload transport rate and grain-size distribution were...
