Q1:Compare the methods of slope stability analysis and write in your own words how the methods are different from one another.

Question 4 a) "SuDS are designed to mirnic the natural rnovement of water and slow down the process of the water getting into the watercourse. They can channel the flow of water above ground and reduce the burden on the piped sewerage system- The Pitt Review 2007. This extraction from the Pitt Review surnmarised the application of Sustainable Drainage Systerns of which there are rnany designs. Briefly explain each of the different types of SuDS noted below. i. Green Roofs ii. Balancing Ponds iii. Infiltration trenches iv. Swales v. Permeable pavements (10) b) The floods for a particular river conform to an Extreme Value Type I (i.e. Gumbel) distribution. If the 100-year flood has a magnitude of 260 ri,/s and the 10-year flood has a rnagnitude of 170 rnsVs. what is the probability of having a flood as great as or greater than 240 rn-, and what is the return period of that event. c) Give 3 examples of Human flood causes (12) (3)

In the past few decades, a fourth industrial revolution has emerged, known as I.R.4.0. I.R.4.0 optimizes the computerization of I.R.3.0, where computers are connected and communicate with one another to ultimately make decisions without human involvement using autonomous systems fuelled by data and machine learning. A combination of cyber-physical systems, the Internet of Things (IoT), access to real-time data, the introduction of cyber-physical systems, and the Internet of Systems make I.R.4.0 possible and the smart factory becomes a reality. I.R.4.0 connects physical with digital and allows for better collaboration and access across departments, partners, vendors, products, and people. As a result of the support of smart machines that keep getting smarter as they get access to more data, the factories will become more efficient, productive, and less wasteful. I.R.4.0 empowers business owners to better control and understand every aspect of their operation and allows them to leverage instant data to boost productivity, improve processes, and drive growth.
I.R.4.0 had been adopted successfully in various industries especially in the manufacturing industry. However, it is rarely adopted in the water industry to date. As a new generation of civil engineers, it is important to know and understand where to adopt IR.4.0 in Civil Engineering especially in the water industry. Besides, it is also important to know the impact and challenges faced in the water industry, and how does I.R.4.0 helps to solve the problems that we are facing in the water industry nowadays.

This is a question on the “Application of I.R.4.0 in Water Industry”.

Write about,

1) Impact, advantage, and disadvantage of adopting I.R. 4.0 in the water industry
2) How does I.R.4.0 help to solve the problems in the water industry

How to size an I section under shear bending? Stress calculation should be done at which points, why? Which of the parameters that affect stress are more critical? What changes when the section is L, rectangular, or U? What additional inspections should be made for a safe design or what principles should be used for the check? How to choose the section or point to be checked? Explain with formulas, figures, and equations.

Please show step by step. Thank you.

Shallow square footing is resting on a dry cohesionless soil. If the groundwater table moves from great depth to ground surface and axial load of the column moves from centroid to e_x = B/3 how will affect bearing capacity (D_f = 0). Assume unite weight of soil is 124.8 pcf.

Define a Primary Standard using the terms public, enforceable, MCL, and health in your definition

A block of weight 12 lbs is placed on a cart of weight 40 lbs that is attached to a spring with a constant of 500 lb/in. The coefficient of static friction between block A and cart B is 0.15, and the coefficient of friction between cart B and the ground is negligible.

a.) Find the maximum amplitude of oscillation of the system to prevent block A from sliding.

b.) Use conservation of energy to determine the maximum velocity and acceleration of the system.

c.) If the cart begins at the maximum amplitude to the right, determine the equation for x(t), v(t), and a(t). [Hint: The template for the equations are in your Physics I book/notes.

Sandstone pore of 20 mm in diameter and 100 mm long with porosity of 15% is prepared for
core flood experiment. The sandstone pore is fully (100%) saturated with water by injecting
water with viscosity of 1cp at volumetric flow rate of 20 cubic mm/sec. A pressure drop of 1
atm was recorded across the pore during the injection process.
i. What is the absolute permeability of the sandstone pore sample in mD?
ii. What is the pore volume of sandstone sample?
