The bankfull dimension of the Little Alamance Creek at this same spot is diagrammed in the trapezoidal shape to the right. The bank top width is 30 feet across and the stream bottom width is 22 feet across, and the height is 12 feet. The slopes on either side are the exact same angle. If the peak velocity of water in a major storm is 400 ft/min, what is the bankfull discharge (i.e., the volume the fills the banks before flooding) in both cfs and cms?

Question
. The bankfull dimension of the Little Alamance Creek at this same spot is diagrammed in the trapezoidal shape to the right. The bank top width is 30 feet across and the stream bottom width is 22 feet across, and the height is 12 feet. The slopes on either side are the exact same angle. If the peak velocity of water in a major storm is 400 ft/min, what is the bankfull discharge (i.e., the volume the fills the banks before flooding) in both cfs and cms? (hint: you can find the equation for the area of a equilateral trapezoid via a google search.)
