Missing precipitation data (hydrology)

Click For Summary
SUMMARY

The discussion centers on the challenge of estimating missing precipitation data for gauge X using adjacent station data amounts of 42.4, 35.3, and 38.4. The participant calculated precipitation at 30-minute intervals using Excel but identified a critical issue: the absence of normal annual precipitation data, which is essential for applying standard methods like the normal ratio or arithmetic mean. The conclusion drawn is that without this data, the question cannot be accurately resolved, indicating a potential editing error in the homework statement.

PREREQUISITES
  • Understanding of hydrographs and rainfall intensity vs time analysis
  • Proficiency in Excel for data calculations
  • Knowledge of normal ratio and arithmetic mean methods in hydrology
  • Familiarity with precipitation data interpretation
NEXT STEPS
  • Research methods for estimating missing precipitation data without annual averages
  • Learn about hydrograph construction techniques in hydrology
  • Explore the use of Excel for advanced data analysis in environmental science
  • Investigate common editing errors in academic questions and their implications
USEFUL FOR

Hydrologists, environmental scientists, students in water resource management, and anyone involved in precipitation data analysis will benefit from this discussion.

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 ?

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.
