a) Sketch the specific energy curves for the following open channel flows:

· A hydraulic jump formed in a rectangular open channel

· Flow through a channel width constriction, where the depths remain subcritical

throughout

· Flow through a sluice gate, where the gate opening is less than the flow’s critical

depth.

· Flow through a combined channel width constriction together with an upward

step, where the depth remains subcritical throughout.

b) Define and explain the following terms

· Critical depth

· The origin or description of the two components of the specific energy for

rectangular channels

· Alternate depths· The origin or description of the two components of the momentum function for rectangular channels

Kanchana has been working as an environmental engineer at a consulting firm for over twenty-five years. Well-known for settling disputes between his corporate clients before litigation must be pursued, Kanchana often analyses technical data, particularly distributions of solid particle pollution, presented by disputing parties to help them reach a compromise on the cost of environmental clean-up. For example, two parties may be separated from one another by a strip of land; however, each party must fiscally contribute in keeping the land free from pollutants.
One day, Kanchana was contacted by a journalist to talk about his experiences at the firm. Kanchana spoke about how he often encountered cases where companies did not accurately depict levels of solid particle pollution occupying the companies’ respective surroundings. Instead, technical experts, who are mostly engineers, would misrepresent data in order to make it seem that minority parties were responsible for a greater part of the contamination. At the end of the interview, Kanchana emphasized the necessity of engineers taking ownership and being honest about the presentation of data.

1. What are the additional factors that might affect capacity and speed on freeways (hint: they don’t always exist, and the adjustment is not carried out if they are irrelevant in a given problem)? How do you make these adjustments?

1. What are the critical geometric parameters for a weaving section analysis?

3. What are the three macroscopic parameters in traffic flow? Which parameters was considered as the independent variable in class (as the switching point between travelers intending to make a trip, and them starting a trip)?

List 3 factors that would affect dozer production. Give an example of a change to one of those factors that would affect production and explain how that change would increase or decrease production.

The shallow sandy aquifer (4 feet thickness) is contaminated with 1,2-XYZ (K oc = 20 L/kg) at an average soil concentration of 800 mg/kg. A batch soil washing device is designed to treat 1,100 kg of contaminated soil (f oc = 0.004) with 900 gallons of clean water. Find the concentration of 1,2-XYZ in water and in soil and water after (a) one wash, and, (b) two wash.

What are the possible reasons for the development of the fractures in the lithosphere?

Q. State and discuss 7 technical challenges faced in water distribution systems [14]   

A community’s groundwater has been contaminated by perchloroethylene after years of operation of a dry-cleaning business. Groundwater supplies a spring that feeds a pond and stream and is also the source for a well. A local family relies on the well for their drinking water and regularly eats fish caught in the stream and pond. The concentration of perchloroethylene in the groundwater is found to be 80 mg/L, and the chronic oral RfD is 0.006 mg/kg/day.

a.) Assuming all exposure to perchloroethylene comes from consumption of fish and water, and that children and adults eat the same amount of fish on average per day, calculate the Estimated Exposure Dose (EED) for an adult and a child.

b.) What are the adult and child hazard ratios (HR) for this scenario? Interpret the results.

The average body weight of an adult is 70kg, the average body weight of a child is 10kg, and the amount of fish consumed is 6.5g/day.

What are the steps for applying the Ishikawa (fishbone) method?
