Physical Process EffectsSediment in Chehalis River

High contributions of sediment are typically associated with land use management practices. Common sources are usually logging roads, landscapes void of vegetation, landslides, and areas of excessive streambank erosion.   High amounts of sediment can cause excessive aggradation downstream and alter substrate composition.
