Problem 2: Designing Culverts Under a Bridge on El Rio de las Aguas Torenciales A 100-year stom event is being considered in order to design the culverts under a bridge. Figure 3 shows the storm event that may fall on the rural watershed of area 3.2 Km that drains into El Rio de las Aguas Torenciales. It generates runoff all over the watershed. The runoff flows into the river towards the ast point A (Figure 4) in the watershed where...

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...
