Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.

Question

Q2) Water is flowing in three side-by-side pipes of diameter (1.8m) each.
The Manning's (n) and the bed slope of each pipe are (0.017) and (1:1000)
respectively. The water depth in each pipe is (1.6 m). After the
development, the discharge above is expected to increase by (25%), and
the engineers have decided to replace the three pipes by a trapezoidal
channel. The new channel should have (n= 0.013) with the same bed slope
,B = 1.15 y , and z=1. Design the cross section of the new channel.

A) A fully penetrating unconfined well of 12 in. The diameter is pumped at a rate of 1 ft^3/sec. The coefficient of permeability is 750 gal/day per square foot. The drawdown in an observation well located 200 ft away from the pumping well is 10 ft below its original depth of 150 ft. Find the water level in the well. B) In addition to the requested information, calculate the radius of influence for the well (in ft). You will get an extremely large and unreasonable value (in the millions...pinky to corner of mouth required). C) Then develop a plot of the water surface profile for the well during pumping. Orient the plot so that the x-axis represents the distance from the production well (and looks like the bottom of the aquifer (i.e., the datum)) and the pumping well is represented by the y-axis and shows the water depth (in feet) in the aquifer. I recommend selecting small intervals (10-20 feet) of x-axis values between the y-axis and 500 feet. Then use increments of 1,000-1,000,000 as…
