Unformatted text preview: B. Conditions promoting aggradation: 1. Increase sediment load 2. Elevated base level 3. Decrease discharge a. Climate change --> drier b. Dams C. Landforms: 1. infilling of channel bed at head of lake 2. Delta formation III. Degradational Landforms A. Capacity > load --> stream has excess energy = erosion, degradation B. Factors promotion degradation: 1. Decreased sediment load 2. Lower base level C. Landforms: 1.Valley incision by stream 2. Dam --> reduces sediment load below dam 3. terrace formation on streams by floodplain...
