Q6/(A)- The return period of a 10cm rainfall in 6 hr occurring at station A is found to be the probability that a 6-hour rainfall of magnitude 10 cm or larger will 1- not occur in station A in 20 successive years. 2-occurs in station A at least once in 20 successive years. 3-occurs in station A once in 50 successive years. ... (B)- Design the most economical section of a rectangular channel to carry 0.3 m³/s of water when the channel bed slope (So) is 1:1000. Assume the manning coefficient (n) is 0.025. GOOD LUCK
