Abstract

The purpose of this three-year study is to describe, explain and predict changes in the geomorphology of the Snake River (from Jackson Lake Dam to Moose) and related changes in riparian vegetation due to Jackson Lake Dam and 1988 fires in the watershed. Specific objectives are to determine changes over time and space in: 1) sediment mobilization on hillslopes from rainsplash and overland flow; 2) sediment delivery to streams from slope failures; 3) equilibrium condition and relative stability of the Snake River; and 4) extent of various riparian vegetation communities in the Snake River floodplain.
