A highway embankment must cross the stream downstream of the gate in Problem 16.13 as shown in Figure P16.14. The embankment is traversed by a 48-in RCP chat is 75 ft long. The channel downstream is the same as in Problem 16.13 and runs on for a long distance. How far downstream of the gate must the embankment be placed so as not to effect the discharge through the gate? Assume the culvert inlet is flush with the embankment.
