The urban tram project, which operates with a light rail system, is planned. In addition to metaformic, sedimentary and magmatic rocks on the ground, unconsolidated fine sand-silt grain size ground materials were also found. Underground water level depth is between 1 and 3 meters. There is a fault zone along the project line. What can be the geotechnical problems that may be encountered before, during and after the project construction, and solutions as a civil engineer?

A clay layer in field is 3-m thick and is sandwiched between two sand layers (drained from top and bottom). The saturated stratum of clay is under a surcharge loading and underwent 90% primary consolidation in 75 days. The time required in minutes for a 30 mm thick undisturbed clay sample obtained from the field to undergo 90% consolidation in laboratory is most nearly equal to

1. In 2015, countries around the world agreed to develop a new set of global goals to eradicate extreme poverty and achieve sustainable development by 2030 through 17 Sustainable Development Goals (SDGs) for the future of the world. No goal or target is considered met unless met for all people, whoever and wherever they are.

a) Briefly explain what the concept of sustainable development means.

b) Illustrate the three pillar model of sustainability. Comment on some of the challenges for sustainable development in our country and suggest a way to overcome the same.

c) The SDG #7 is to ensure access to affordable, reliable, sustainable and modern energy for all.

(i) Differentiate between conventional and non-conventional energy sources. Which will you support? Why?

(ii) Going green can reduce the overall energy use. Mention any two strategies that you could adopt to meet the sustainability benchmarks.

2. Air pollution in Asia has worsened since 2000 and is responsible for deaths of thousands of people in Beijing, Jakarta, Seoul and Manila. The pollution is a result of the use of fossil fuels by the industry and transport sectors. The problem got aggravated in Asia due to the use of poor quality fuel, inefficient method of energy production, use of vehicles in poor condition and traffic congestion. This was revealed during a research conducted by World Bank and Stockholm Development Institute. The research states that air pollution in the continent has surpassed the combined emissions in Europe and North America. The deaths caused by fine particulate matter far exceed those caused by sulphur dioxide, nitrogen oxide, ozone and lead. The health cost in major Asian cities now exceed for 15-18 percent of urban income expenditure, claims World Bank officials.

a) A comprehensive campaign to address air pollution need to be launched through school children, what programme (one) would you envisage for this. What is outcome anticipated?

b) There is a sudden decision to remove all vehicles from the road that fails to meet specified norms of emission level within a specified time period. As part of citizen forum you are requested to give views on the enforced regulation. State your views on this.

c) A massive campaign on environmental degradation is to be initiated. Bring out a slogan and the key message that need to be addressed.

d) Suppose you are a Carbon Credit Auditor appointed to assess the greenhouse gas emission reduction strategies. Identify a component of assessment and brief the methodology that could be adopted in connection with this.

Provide 3 areas in Engineering Grand Challenges that are highly RELATED to Civil Engineering or Construction Engineering Management fields. Why are they associated with CECEM?

While working for a client, an engineer learns confidential knowledge of a proprietary production process being used by the client’s chemical plant. The process is clearly destructive to the environment, but the client will not listen to the objections of the engineer to release information that was gained in confidence. Is it ethical for the engineer to expose the client? Why?

Which of the following is true about hydraulic jump?

- A reduction in slope can cause a hydraulic jump

- in increase in manning's roughness can cause hydraulic jump

- An increase in slope can cause a hydraulic jump

- A smoother steeper channel will cause a hydraulic jump

- A hydraulic jump results in a reduction of total head

- A hydraulic jump results in an increase of total head

A car is traveling up a 1.5% grade at 65 mi/hr on good, wet pavement. The driver brakes to try to avoid hitting a cone on the road that is 300 ft ahead. The driver’s reaction time is 1.5 second. When the driver first applies the brakes, a software flaw causes the braking efficiency to lower to 0.8 for 100 ft. After the initial 100 ft, the braking efficiency returns to 1.0. How fast will the driver be going when the cone on the road is hit if the coefficient of rolling resistance is constant at 0.015? (Assume minimum theoretical stopping distance and ignore aerodynamic resistance.)
