1) Were the designers aware that this valley was landslide-prone before they built the dam? What feature of Fig. 1 suggests an answer?
2) Read the description of the Malm Formation under "The geologic setting". List all words here that you are certain are significant in conveying to the reader a problem with respect to slope stability.
3) Note the wide U-shaped profile of the upper (outer) portion of the valley as opposed to the steep V-shaped profile of the lower (inner) portion of the valley. Can you explain why this form exists? Is the form meaningful in terms of the dam?
determine the force exerted by the rider on the seat, the upward normal forces at A and B, and the lateral friction forces at A and B. Even though the bicycle is free to roll, assume that it does not. The bicycle weighs 29 lb with center of gravit..
FeCl3 is added to remove excess phosphate. The following reactions occur (the charges are in parentheses): FeCl3 -> Fe(3+) + 3Cl(-) Fe(3+) + PO4(3-) -> FePO4 The equilibrium constant for the second reaction is 10^26.4.
You add 100 mg/L of glucose to pure water, then decide that this was a mistake and decide to remove it biochemically before you serve the water to your friends at a cocktail party. To remove the glucose, you seed the water with a harmless bacteria..
Determine the maximum possible precipitation at New York City that may be encountered on a 100 mi^2 drainage area over a 96 hr period.
A rectangular open channel with a width of 10 ft and n = 0.013 conveys a discharge of 300 cfs. The upstream portion of the channel has a slope of 10%, which then abruptly changes to a slope of zero downstream.
Consider a 1000 acre residential area with a housing density of four dwellings per acre. Evaluate the peak hourly water use requirement.
A storage pile of crushed rock is 100ft by 100ft square at its base and 50 ft by 50 ft square on the top. The pile is 25 ft high. What is the volume of rock in the rock pile
The stream hts a stationary splitter, such that half of the flow is diverted upward at 45o. and the other half is directed downward, and both streams have a final speed of 18ft/s.
Dust is removed from the airstream of a municipal incinerator by four dust collectors operating in parallel, each handling 1/4 of the total airflow of 200 m3/min. The airstream contains 10 g/m3 of suspended solids.
Determine the operating speeds of the machine at which the machine's steady-state amplitude is less than 0.2 mm. Take keq = 3 EI/L3.
find the unknown quantity in each of the following, using the standard series equivalence formulas and tables in the Appendix. Give preference to the approach yielding the fewest computational steps.
Consider an L-shaped breakwater that protects a small harbor dredged to a uniform depth of 6 m. For a 2 m high, 10 s period incident wave at the head of the breakwater having incident wave direction of 60 degrees
