An agricultural runoff diversion system discharges into a small river. The runoff has thefollowing characteristics: flow = 100 m3/min, DO = 3 mg/L, and BOD = 150 mg/L. The riverflows at1000 m3/min and has zero BOD and 9 mg/L of DO. Given that saturation DO is 9.5mg/L, kd is 0.4 day-1, and the ka is 0.7 day-1, calculate the DO and BOD remaining in the stream1.5 days after the discharge event.

An industrial plant discharges water into a river. An environmental protection agency has studied the discharged water and found the lead concentration in the water (in micrograms per litre) has a normal distribution with population standard deviation σ = 0.7 μg/l. The industrial plant claims that the mean value of the lead concentration is 2.0 μg/l. However, the environmental protection agency took 10 water samples and found that the mean is 2.56 μg/l. A hypothesis test is carried out to...

The city of Imaginopolis, which is located near White River, has an elaborate system of levees to protect the city from flooding during high-water events. The levees were built over 50 years ago and many of them are showing signs of structural distress. Using a systems perspective, how would you draw up a program to rehabilitate the levee system under budgetary constraints over a 5-year period?

A 360-m-wide river has a uniform flow speed of 1.5 m/s through a jungle and toward the east. An explorer wishes to leave a small clearing on the south bank and cross the river in a powerboat that moves at a constant speed of 5.8 m/s with respect to the water. There is a clearing on the north bank 65 m upstream from a point directly opposite the clearing on the south bank. (a) At what angle, measured relative to...
