A 50 –acre watershed located near El Paso has the following land uses: 30 acres poor condition range (Soil Group B), 15 acres residential (3 acre lots, Soil Group B), and 5 acres business (85% impervious, Soil Group C). The watershed has a maximum flow length of 2000 feet on a 3% slope. No significant water ponding occurs within the watershed. Soils are dry at the start of the storm events.

Required:
a. What is the peak runoff estimate using the Rational Method.
b. What is the peak runoff estimate using the SCS TR-55 method.
c. Which method do you choose to estimate peak runoff and why did you choose that method.
d. What is the peak runoff for the 100-year, 24-hour storm?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
