Please Answer: 3, 7-9
QUESTION 1 Cougar Run flows from the west to the east (see figure below showing the location of the river, your factory, a factory built in 2004, local farms (A-F), and water wells). Based on the shape of the stream channel, consider where one would expect significant erosion or deposition to occur. Based on your evaluation of the the figure below, which landowners (A-F) could experience the worst erosion damages to their property? Owell well Cougar Run Location of Your Factory well well Factory Built in 2004 1 km 0 0 0 0

Answer 1

Question 3: See image

Question 8:

Part 1: Since the water is acidic it will increase erosion by eroding the constructions and that will lead to urban flooding.

Part 2: Since the flow velocity is not very high and the river is meandering the acidic water gets sufficient time to infiltrate down the subsurface by the action of gravity and affect the ground water.

Question 9: It is the job of engineers to provide model.

Виох, ол 3 erode the fertile soil the stream To must be travelling fast enough to pick up the sand frilt and transport it downstream. Practice using the "velouty" us particle size" guaph found below by filling in the blanks below. • Sand particles that care 0.03 mm in size will be eroded when water teranels at 30unk. • Deposition starts to occur at 20 unk on 0,2 ml for particles bumin size. • To pick up Cerode ) and transport Larger particles , inuch higher newities and needed. To move cobbles that are 200mm (or 20cm in size), water veloutien must be at least 500 ans or sunk Pebbles (50mm) being tremported will begin to be deposited when water veldcity drops below so unkom Ove mk.
