Duration of Rainfall from Rainfall Hyetograph Solution

STEP 0: Pre-Calculation Summary
Formula Used
Duration = Pulses of Time Interval*Time Interval
D = N*Δt
This formula uses 3 Variables
Variables Used
Duration - (Measured in Hour) - Duration is used to measure the response time of any event.
Pulses of Time Interval - Pulses of Time Interval Observed in Rainfall Hyetograph.
Time Interval - (Measured in Hour) - Time Interval is the amount of time required for the change from initial to the final state.
STEP 1: Convert Input(s) to Base Unit
Pulses of Time Interval: 6 --> No Conversion Required
Time Interval: 3 Hour --> 3 Hour No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
D = N*Δt --> 6*3
Evaluating ... ...
D = 18
STEP 3: Convert Result to Output's Unit
64800 Second -->18 Hour (Check conversion here)
FINAL ANSWER
18 Hour <-- Duration
(Calculation completed in 00.004 seconds)

11 Φ-Index Calculators

Precipitation given Total Runoff Depth for Practical Use
Go Total Storm Precipitation = Total Direct Runoff+(Φ-Index*Duration of Rainfall Excess)
Duration of Rainfall Excess given Total Runoff Depth
Go Duration of Rainfall Excess = (Total Storm Precipitation-Total Direct Runoff)/Φ-Index
Phi Index given Total Runoff Depth
Go Φ-Index = (Total Storm Precipitation-Total Direct Runoff)/Duration of Rainfall Excess
Total Direct Runoff Depth
Go Total Direct Runoff = Total Storm Precipitation-(Φ-Index*Duration of Rainfall Excess)
Runoff to Determine Phi Index for Practical Use
Go Runoff in Cm from 24h Rainfall = Coefficient Depending on Soil Type*Intensity of Rainfall^1.2
Rainfall Intensity for Phi Index of Practical Use
Go Intensity of Rainfall = (Φ-Index*24)+Runoff in Cm from 24h Rainfall
Runoff for Phi Index for Practical Use
Go Runoff in Cm from 24h Rainfall = Intensity of Rainfall-(Φ-Index*24)
Phi Index for Practical Use
Go Φ-Index = (Intensity of Rainfall-Runoff in Cm from 24h Rainfall)/24
Pulses of Time Interval from Rainfall Hyetograph
Go Pulses of Time Interval = Duration/Time Interval
Duration of Rainfall from Rainfall Hyetograph
Go Duration = Pulses of Time Interval*Time Interval
Time Interval of Rainfall Hyetograph
Go Time Interval = Duration/Pulses of Time Interval

Duration of Rainfall from Rainfall Hyetograph Formula

Duration = Pulses of Time Interval*Time Interval
D = N*Δt

What is a Rainfall Hyetograph?

A Hyetograph is a graphical representation of the distribution of rainfall intensity over time. For instance, in the 24-hour rainfall distributions as developed by the Soil Conservation Service, rainfall intensity progressively increases until it reaches a maximum and then gradually decreases.

How to Calculate Duration of Rainfall from Rainfall Hyetograph?

Duration of Rainfall from Rainfall Hyetograph calculator uses Duration = Pulses of Time Interval*Time Interval to calculate the Duration, The Duration of Rainfall from Rainfall Hyetograph formula is defined as the total duration in hours depending upon the size of the catchment and storm characteristics. Duration is denoted by D symbol.

How to calculate Duration of Rainfall from Rainfall Hyetograph using this online calculator? To use this online calculator for Duration of Rainfall from Rainfall Hyetograph, enter Pulses of Time Interval (N) & Time Interval (Δt) and hit the calculate button.
