Cool TS, I found some great info. !there is a very old document called rainfall in Burma in 1965, wondering how reliable it is after 50 years, but it will definitely good supporting doc for a very rough assumptions.
Thanks
Yes Beej, you got it, we don't have that luxury to get every data we need, not even basic set of data. In the worst scenario, I will use nearby country available IDF, pick out an area with similar geographic/climate characteristics.
Thanks Beej, until when I get more data, for now I was wondering if I can make the following rough assumptions:
1. The data is 1-yr storm event
2. Heaviest rain is in Oct of 7.3 inch, 7 rainy days in the month -> 7.3/7 = 1.1 inch -> 1-Yr storm, 24 hr storm duration
Thanks
Thanks Peter, I will ask local government for more rainfall amount from 5min to 24hr. The worst case do you think 60min is okay to use it as 1hr design point rain fall? What about frequency? do you think the probability of rainny day comes with the data set will give us safe assumption about...
Dear all experts,
I'm civil engineer an have very basic understanding of hydrology. In my past with hydrology/hydraulic cals, IDF were given. This time, I work on a project oversea that requires some basic drainage cals but all I have is precipitation data from this website...
