Rainfall Intensity vs Storm Duration

Formula

## Rainfall Intensity Rainfall intensity is the rate of rainfall, critical for sizing stormwater drainage systems. ### Formula **i = P / t** where P is the total depth of rainfall (mm) and t is the duration (hours). Shorter, more intense storms require higher drainage capacity. Design storms are typically characterised by intensity-duration-frequency (IDF) curves.

Esempio Risolto

50 mm of rain over 30 minutes.

  1. 01Duration in hours = 30 / 60 = 0.5 h
  2. 02Intensity = 50 / 0.5 = 100 mm/h
  3. 03This is a relatively intense rainfall event.
