Distribution of bedrock and alluvial channels in forested mountain drainage basins
Article Abstract:
A threshold model that links sediment content to sediment transport capacity explains the distribution of alluvial and bedrock channels in the Satsop River basin, Washington. Tree logs that block sediment movement and backward flow induce the formation of alluvial channels in bedrock channel areas. Forest management methods of removing big trees have a harmful effect on ecology as this prevents the formation of alluvial channels that support aquatic life. The bedrock channels are found on steeper slopes as they are relatively unaffected by sediment supply or discharge variations.

Episodic sediment accumulation on Amazonian flood plains influenced by El Nino/Southern Oscillation
Article Abstract:
The transient processes driven by the El Nino/Southern Oscillation cycle control the formation of the Bolivian flood plains and modulate downstream delivery of sediments and also associates carbon, nutrients and pollutants to the Amazon main stem.
