2. Design a trapezoidal vegetative waterway that has a side slope of 4:1, a slope of 4%, flow equal to Q= 75 cfs, an erosion resistant soil, and the grass mixture grown to 2 inches in height

1. What is the difference betw een direct and indirect site characterization methods? 2. Give an example of direct measurement method? 3. Give an example of indirect measurement method?

I DOWNVOTE for incorrect answers.
Explain the helicoidal flow theory required.

1.Describe the four stages to Project Life Cycle. Discuss in your own words the key documents likely to be utilized by the PM for each stage. Provide a template as an example for each one.

1. As an Geotechnical Engineer for a company you have been instructed to handle a project to develop a new Mall. The project currently in construction stage. During process of pile installation, the contractor notices few problems with the site condition:

1. Limited area for work space which might have problem to use conversional method for pile installation.
2. Project site is near with Hospital (contractor must control the sound pollution).

As a consultant you are need to solve these problems and need to suggest (with explanation) suitable method to install the pile.

2. After complete installation of pile, you are need to suggest method/s to conduct pile test (with explanation).

A natural soil slope failed overnight after experiencing several days of rainfall.  The rain continued even after the slope failure.  The shape of the failure resembled a spoon (i.e., circular failure).  You are the consulting engineer hired, please answer the following questions:

i.  In order to confirm the stability of the slope prior to the rainfall induced failure (when it was stable), what Shear Strength parameters you will likely use in this calculation? Why?

ii.  In order to explain the slope failure, i.e., for your slope stability model of the slope at failure, what Shear strength parameters will you likely use in this calculation? Why?

1. The image of a point whose elevation is 1,475 ft above datum appears 53.87 mm from the principal point of a vertical photograph taken from a flying height of 6,000 ft above datum. What would this distance from the principal point be if the point were at datum?

2. Images a, b, and of ground points A, B, and C appear on a vertical photograph taken from a flying height of 8,350 ft above datum. A 6-in-focal length camera was used. Points A. B. and C have elevations of 1.725 ft, 1.640 ft, and 095 ft above datum, respectively. Measured photocoordinates of the images are xa= -371 in, ya= 1.864 in, xb=062 in. yb = 3.183 in, xc=3.704 in, and yc=-3.138 in. Calculate the lengths of the lines AB, BC, and AC and the area within the triangle ABC.

3. The images of the top and bottom of a utility pole are 5.11 in and 4.93 in, respectively, from the principal point of a vertical photograph. What is the height of the pole if flying height above the base of the pole is 2,850 ft?

4. An area has an average terrain elevation of 1,200 ft above datum. The highest points in the area are 1,850 ft above datum. If the camera focal plane opening is 9 in square, what flying height above datum is required to limit relief displacement with respect to average terrain elevation to 0.20 in? If the camera focal length is 8in, what is the resulting average scale of the photography?

5. The datum scale of a vertical photograph taken from 3,000 ft above datum is 1:6,000. The diameter of a cylindrical oil storage tank measures 6.87 mm at the base and 7.01 mm at the top. What is the height of the tank if its base lies at 590 ft above datum?

6. Assuming that the smallest discernable and measurable relief displacement that is possible on a vertical photo taken from 3,000 ft above ground is 0.5 mm, would it be possible to determine the height of a telephone utility box imaged in the comer of a 9-in-square photo which stands 4 ft high above the ground?

7. If the answer to Prob.6 is yes, what is the maximum flying height at which it would be possible to discern the relief displacement of the utility box? If the answer is no, at what flying height would the relief displacement of the box be discernable?

part 1) A deep excavation (choose all that apply):

Needs to consider Lateral Pressures

Are possible only if the soil is cohesive

Must consider the need for dewatering

Can use braces if needed

Requires Engineering Design
