Time of Peak given Base Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time of Peak = Base Length/2.67
T_p = T_b/2.67
This formula uses 2 Variables

Variables Used

Time of Peak - (Measured in Hour) - Time of Peak is the time interval from the start of rainfall to the peak discharge.
Base Length - (Measured in Meter) - Base Length in SCS Triangular Unit Hydrograph is a popular method used in watershed development activities, especially in small watersheds.

STEP 1: Convert Input(s) to Base Unit

Base Length: 18.69 Meter --> 18.69 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_p = T_b/2.67 --> 18.69/2.67

Evaluating ... ...

T_p = 7

STEP 3: Convert Result to Output's Unit

25200 Second -->7 Hour (Check conversion here)

FINAL ANSWER

7 Hour <-- Time of Peak

Time of Concentration given Time of Peak

Go Time of Concentration = (Time of Peak-(Standard Duration of Effective Rainfall/2))/0.6

Duration of Effective Rainfall for given Time of Peak

Go Standard Duration of Effective Rainfall = 2*(Time of Peak-0.6*Time of Concentration)

Time of Peak given Time of Concentration

Go Time of Peak = 0.6*Time of Concentration+Standard Duration of Effective Rainfall/2

Duration of Effective Rainfall given Time of Peak

Go Standard Duration of Effective Rainfall = 2*(Time of Peak-Basin Lag)

Time of Peak or Time of Rise

Go Time of Peak = (Standard Duration of Effective Rainfall/2)+Basin Lag

Lag Time given Time of Peak

Go Basin Lag = Time of Peak-Standard Duration of Effective Rainfall/2

Catchment Area given Peak Discharge

Go Area of Catchment = Time of Peak*Peak Discharge/2.08

Time of Peak given Peak Discharge

Go Time of Peak = 2.08*Area of Catchment/Peak Discharge

Peak Discharge

Go Peak Discharge = 2.08*Area of Catchment/Time of Peak

Time of Recession as Suggested in SCS

Go Time of Recession = 1.67*Time of Peak

Time of Peak given Time of Recession

Go Time of Peak = Time of Recession/1.67

Base Length in SCS Triangular Unit Hydrograph

Go Base Length = 2.67*Time of Peak

Time of Peak given Base Length

Go Time of Peak = Base Length/2.67

Time of Peak given Base Length Formula

Time of Peak = Base Length/2.67
T_p = T_b/2.67

What is Basin Lag?

Basin lag time, defined as the elapsed time between the occurrences of the centroids of the effective rainfall. and of the storm runoff hydrograph, is an important factor in determining the time to peak of the unit. hydrograph and the intensity of peak discharge.

What is Baseflow?

Baseflow is a portion of streamflow that is not directly generated from the excess rainfall during a storm event. In other words, this is the flow that would exist in the stream without the contribution of direct runoff from the rainfall.

How to Calculate Time of Peak given Base Length?

Time of Peak given Base Length calculator uses Time of Peak = Base Length/2.67 to calculate the Time of Peak, The Time of Peak given Base Length formula is defined as the time interval from the start of rainfall to the peak discharge. Time of Peak is denoted by T_p symbol.

How to calculate Time of Peak given Base Length using this online calculator? To use this online calculator for Time of Peak given Base Length, enter Base Length (T_b) and hit the calculate button. Here is how the Time of Peak given Base Length calculation can be explained with given input values -> 0.001944 = 18.69/2.67.

FAQ

What is Time of Peak given Base Length?

The Time of Peak given Base Length formula is defined as the time interval from the start of rainfall to the peak discharge and is represented as T_p = T_b/2.67 or Time of Peak = Base Length/2.67. Base Length in SCS Triangular Unit Hydrograph is a popular method used in watershed development activities, especially in small watersheds.

How to calculate Time of Peak given Base Length?

The Time of Peak given Base Length formula is defined as the time interval from the start of rainfall to the peak discharge is calculated using Time of Peak = Base Length/2.67. To calculate Time of Peak given Base Length, you need Base Length (T_b). With our tool, you need to enter the respective value for Base Length and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Time of Peak?

In this formula, Time of Peak uses Base Length. We can use 4 other way(s) to calculate the same, which is/are as follows -

Time of Peak = (Standard Duration of Effective Rainfall/2)+Basin Lag
Time of Peak = Time of Recession/1.67
Time of Peak = 2.08*Area of Catchment/Peak Discharge
Time of Peak = 0.6*Time of Concentration+Standard Duration of Effective Rainfall/2
