[University Hydrology] - Creating a storm hydrograph from a 60 minute unit hydrograph with hourly net rainfall.

Relevant Equations

None

Hi guys,

not sure if anyone can help me but I'm having a bit of an issue with creating a storm hydrograph from a 60 min unit hydrograph that is in 5 minute intervals.

I've lagged the unit hydrograph by 60 minutes each net rainfall block while multiplying the respective net rainfall to the respective UH values but it gives me a really odd hydrograph when i plot it.

If i lag the UH by the 5 minute intervals for each net rainfall block i get a more respectable shape but it doesn't seem like its the right way to do it.

I can attach my spreadsheet if needed
