• 1.1 Q (Water Discharge)

this is adjusted by changing the flow of water added to the flume.

• 1.2 S (Slope)

This is adjusted by changing the Hight of one end of the flume.

• 1.3 Qs (Sediment Discharge)

this is controlled by amount of flow and size of grains added to the flume.

• 1.4 Profile

this is controlled by a combination of slope, water flow, and grain size.

• 1.5 Base Level

this can be controlled by filling part of the flume with water.

• 2.1 Bed Erosion

marked in red

• 2.2 Bank Erosion

marked in green

• 2.3 Deposition

marked in areas of purple

• 2.4 Sediment Transport

marked in blue

• 4.1 Small Flood

increased flow and sediment transport

• 4.2 Big Flood

large increase in flow banks are eroded

• 4.3 Channel Realignment (Grading)

sediment is deposited in a sorted manner by grainsize and shape

• 4.4

During the small flood event there was increased bed and bank erosion along with sediment transport. the large flood event caused extensive erosion of bed and bancs along with avulsing sediment in some areas.

• 4.5

Most of the water flow was brace or bank full, with over bank flow quickly leading to channel incision.

• 4.6

Hyporheic flow most likely occurred in the flue experiments due to the loosely packed grains but was not easily observed.

• 4.7

Recession limb flows were present after the water flow in the flume was decreased.
