Missing precipitation data (hydrology)

AI Thread Summary
The discussion centers on a homework problem requiring the development of a hydrograph and estimation of missing precipitation data for gauge X based on adjacent stations A, B, and C. The user calculates precipitation at 30-minute intervals but questions the validity of the problem due to the absence of normal annual precipitation data, which is typically necessary for such calculations. There is a suggestion that the question may contain an editing error, indicating a lack of connection between its two parts. If treated as separate questions, the arithmetic method could still be applied to estimate the missing data. The overall consensus is that the problem may be flawed or incomplete.

Homework Statement


Develop a hydrograph (rainfall intensity vs time) for the precipitation data . Then , estimate the amount of gauge
X if there adjacent station precipitation amount of A , B and C are 42.4 , 35.3 and 38.4 respetively .

Homework Equations

The Attempt at a Solution


So , i calculate the precipitation at 30 mins interval first , as shown in the excel file .

I think there's something wrong with this question . Normally this type of question ( when we are asked to find the missing precipitation data) , we would use normal ratio or arithmethic mean method ...

In both cases , the normal annual precipitation is needed . But , in this question , the normal annual precipitation isn't provided .So , i think this question can't be done .

Is my concept correct ?

P/s : The data is in photo 713

As far as I can make out, there is no connection between the first part of the question and the second. This suggests an editing error. If they really are two separate questions, you have no choice but to assume the arithmetic method can be applied.
