Rainfall intensity-duration-frequency relationship provides valuable information for the use of design engineers or hydrologists, in designing runoff controlling structures for moderating flood control projects. Inadequacy of such information will lead to wrong assumption and unjustified use of factor resulting in heavy expenditure. Out of different rainfall characteristics, rainfall intensity is by far the most important one. The intensity of rainfall is inversely proportional to its duration of occurrence and directly proportional to the return period. With an increase in duration, there is...
