Requirementsprecipitation Intensity
A precise tool.
What is the Requirementsprecipitation Intensity & How does it work?
Rainfall intensity is a fundamental parameter in hydrology, representing the rate at which precipitation falls over a given period.
It is commonly expressed in millimetres per hour (mm/h) and is derived from the total depth of rainfall divided by the duration of the event.
Design storms for infrastructure are often specified by a return period, indicating the likelihood of a storm of a certain intensity occurring.
I = frac{P}{t}
I = intensity (mm/h) P = rainfall depth (mm) t = duration (h)

Frequently Asked Questions
How do I calculate rainfall intensity?
Rainfall intensity is calculated by dividing the total rainfall depth (in millimeters) by the duration of the event (in hours).
What units are used for rainfall intensity?
Rainfall intensity is typically expressed in millimeters per hour (mm/h).
Why is rainfall intensity important in infrastructure design?
It helps engineers design structures that can withstand expected storm conditions, ensuring safety and functionality.
What does the return period of a storm indicate?
The return period indicates how often a storm of a certain intensity is expected to occur, used in designing for extreme events.
How can I convert rainfall intensity from mm/h to inches per hour (in/h)?
To convert mm/h to in/h, multiply the value by 0.03937.
What factors affect rainfall intensity?
Factors include temperature, humidity, wind speed, and atmospheric stability, among others.
Can this calculator be used for snowfall intensity as well?
While the formula is similar, snowfall intensity is typically expressed in different units (e.g., inches per hour) and may require adjustments based on specific conditions.
