502. A gate is to be suddenly dropped into place closing a rectangular channel 

 6 feet deep and 10 feet wide, in which 200 c.f.s. are flowing at a depth of 4 feet. 

 Will the canal overflow? Assuming the sides of the channel to be sufficiently high 

 to prevent it from overflowing, what will be the velocity of the traveling jump 

 produced ?
