Your engineering firm has been hired as a consultant to evaluate engineered channels to replace an existing natural stream. The
existing channel has a length of 1.2 miles with an average bedslope of0.0042ft/ft. Thedesign flowfor this channel is2,250 cfs.The client requests that you conduct a feasibility study to replace the natural stream with a concrete-linedchannel. Base your design on the best hydraulic section and select two of the following section shapes to evaluate:rectangular, trapezoidal, triangular, and half-circularsections.Provide a freeboard of at least 10% of the flow depthat design discharge. Subcritical flowis preferredin the engineered channel. After completing the design of the channel, perform an extreme event analysis by determining the normal depth for a flow of twice the design flow. Discuss ifflooding is an issue for this extreme event.

Answer:
Stat PVC = Stat(82+98.5)
Stat PVT = Stat(59+71.5)
Explanation
PVI = 71 + 35
Let G1 = Grade 1; G2 = Grade 2
G1 = +2.1% ; G2 = -3.4%
Highest point of curve at station = 74 + 10
General equation of a curve:
At highest point of the curve
Station PVT
Answer:
The following command is issued
in Windows command prompt
followed by the HTTP GET
message to the “utopia.poly.edu"
web server:
> telnet utopia.poly.edu 80
As the index.html page in the web
server was not modified since
Mon, 18 May 2015 09:23:34GMT,
the following outputwas displayed
when the above commands were
issued on Sat, 23 May 2015.
The first 4 lines are the GET
message and header lines input by
the user.
The next 4 lines (starting from
HTTP/1.1 304 Not Modified) are
the response from the web server.
