    Sir, how to make the depth duration frequency (DDF) curves?

    Good afternoon, sir.
    I want to know how IDF curves can be applied in the design of an engineering (hydraulic) structure. Can I get a case study, please?

    sir, i have a question, i hope you still tune on
    in mononobe equation, you have I = R24/24 x (24/t)^ (2/3)
    if i take R24= 1 unity, i have an intensity of 0.347 R24 if duration of rain is 1 hour and 0.042 if duration of rain is 24 hr
    my question is, how do you understand this?
    if this rain extend for 24 hour then the amount of rain is 0.042 x 24 = ~ 1. in my understanding, the rain intensity is linear/ stagnant and the rain last for 24 hour
    but if i apply the same logic, if the rain only last for 1 hour, the amount of rain in that hour is only 0.347 or 34.7% from R24 that we usually interpret as daily rainfall for x return period. So where does the rest (0.653 unity) rain go? The rain for that day only last for 1 hour , right?
    is there another 1.88 hour of rain (i get this from 0.653/0.347) that happens in that day that happens in different time? let us say, 1st rain happen during 1 am to 2 am then there are other rain that happen lets say 3 pm to 4 pm and another one at 7 pm to 53 min pass 7 pm (this is 0.88 hour) ? Is this how you interpret the mononobe theory?
