Rainfall Intensity
Civil Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Rainfall intensity is the rate of precipitation over a given duration, typically expressed in millimeters per hour. It is used in designing drainage systems and calculating runoff using the rational method.
Example in context
“The rainfall intensity for a 10-minute duration storm is needed to design the street gutters.”
“10 dakika süreli bir fırtına için yağış yoğunluğu, sokak oluklarını tasarlamak için gereklidir.”
Where engineers use it
Rainfall intensity-duration-frequency (IDF) curves are standard tools used by engineers to determine design storm intensities. This parameter directly influences the sizing of culverts and storm drains.
Practice: can you use “Rainfall Intensity” at work?
You are tasked with designing a stormwater management system for a new parking lot. Determine the critical rainfall intensity for the design storm.
Show a model answer
“The rainfall intensity is derived from the local IDF curve.”
