2) (a) Using the data from your chart on the previous page, and the Earth Science Reference Table page 6 “Relationship of Transported Particle Size to Water Velocity” graph, determine the size of the sediment the stream could carry at locations A and B. Record both sizes below: Size of particle that should be carried in location A: _________ cm Size of particle that should be carried in location B: _________ cm Draw to scale a sediment with the maximum size that could be transported at Location A and Location B in the space below Location A Location B (b) Using a ruler the students found pieces of sediment of the approximate sizes that the chart showed could be transported. They took the sediment samples to the stream, dropped them in one at a time and observed what happened. Here are their results: Location A: Of two particles, one particle failed to move, the other bounced downstream along the bottom. Location B: Of two particles, one particle failed to move, the other rolled downstream along the bottom.
Questions - Station #1 1) (a) How did the velocity of the stream at Location A compare to Location B? (b) The stream discharge at both locations is the same. In light of this, explain the difference in the velocities below. 2) (a) How did the size of the sediment that could be carried by the stream at location A compare to location B? (b) Explain the difference in the size of sediment that can be transported. 3) (a) Did all the sediments dropped in the stream keep moving? (b) Assuming that the student calculations and measurements were correct, what factors might account for sediments that were not carried? (Hint: Carefully examine ESRT page 6) (c) By what method did sediments of the maximize size that were transported at Locations A and B move? Location A: Location B: 4) State the relationship that exists between: a) gradient and velocity: b) velocity and particle size carried by stream:
