Answer each question thoroughly and clearly using a combination of written statements,diagrams, plots, and/or worked out equations to arrive at and explain your answer. Bequantitative whenever possible. Since you will have access to a wide variety of resources, Iam expecting very well thought out responses, presented professionally in order to earn agood grade. Pretend I am your boss, and you are preparing a report. It should be complete,to the point, and straightforward to read, and it should convince me that you completelyunderstand each of the topics.When using equations, always explain why the equations you choose are appropriate foranswering the question, and what assumptions are being made. Use complete sentencesorganized into short paragraphs when necessary for your written responses.Explaining your thought processes and demonstrating your deeper understanding of thematerial is just as important as arriving at a technically correct answer.If you get stuck on a question due to lack of information provided, chances are you eitherneed to look up a typical value (e.g. density of a rock type) or should search a bit harder foranother equation that will let you solve for an unknown variable.
Good luck! Email or stop by my office with clarifying questions.
Questions:
1. Over the course of the term, we calculated the shear stress on the failure plane of alandslide, at the bed of a river, under wind, and beneath a glacier. List each of theseequations, and explain what assumptions the equations have in common as well aswhat assumptions are different among the 4 equations.
2. The picture on the next page shows a granite boulder about 0.5 m in diameter at thebottom of a canyon in eastern Washington that was carved by the Missoula floods.
The canyon is about 600 m wide at this location. Assuming that the granite boulderwas transported as bedload during the floods, estimate what each of the followingwas when the boulder was being transported: water velocity, Reynolds and Froudenumbers of the flow, water depth, water surface slope, and discharge
