A. Compare and contrast the following: design period, returnperiod, design life.
B .What return period is required in the design of a drain inorder to carry 10% risk of flooding in the next 3 years? How doesthe risk in this design vary as the return period is increased(answer both qualitatively (i.e., conceptually) and quantitatively(i.e., mathematically)? How does the risk vary as the recurrenceinterval is increased (answer both qualitatively andquantitatively)?
