GEOG 101 Lecture Notes - Lecture 22: Suspended Load, Bed Load, Aggradation
Document Summary
4 main river patterns defined according to channel. Few streams are straight for any great distance. Some rivers in the western interior plains and parts of the st. lawrence. Portions are described as pools and ripples. Calm water and deeper water in pools. Ripples 5-7x greater than the width of the channel. Coarse material is deposited at the top of the stream. Water moves slowly down the stream and transports a. Characterized by aggregation lot of suspended debris. When the channel bed builds up over time. Falls between the very strong and weak river channel. Coarser material than anastomosed, finer than braided. Dissipates the greatest amount of energy using the least amount of time. Usually occurs when there is an excess of bed load and suspended load. One of the most important expressions of channel flow. Determines the rate of erosion, sediment transport and instability. Where floodwaters are moving from adjacent land into rivers that have no yet.
