Basin Lag given Peak Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Basin Lag = 2.78*Regional Constant (Snyder)*Area of Catchment/Peak Discharge
t_p = 2.78*C_p*A/Q_p
This formula uses 4 Variables

Variables Used

Basin Lag - (Measured in Hour) - Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.
Regional Constant (Snyder) - Regional Constant (Snyder) is considered an indication of the retention and storage capacity of the watershed.
Area of Catchment - (Measured in Square Kilometer) - Area of Catchment is the geographical area from which water flows into a particular point, such as a well, stream, or reservoir.
Peak Discharge - (Measured in Cubic Meter per Second) - Peak Discharge is the maximum volume flow rate passing a particular location during an event.

STEP 1: Convert Input(s) to Base Unit

Regional Constant (Snyder): 0.6 --> No Conversion Required
Area of Catchment: 3 Square Kilometer --> 3 Square Kilometer No Conversion Required
Peak Discharge: 0.891 Cubic Meter per Second --> 0.891 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_p = 2.78*C_p*A/Q_p --> 2.78*0.6*3/0.891

Evaluating ... ...

t_p = 5.61616161616162

STEP 3: Convert Result to Output's Unit

20218.1818181818 Second -->5.61616161616162 Hour (Check conversion here)

FINAL ANSWER

5.61616161616162 ≈ 5.616162 Hour <-- Basin Lag

What is lag time in hydrology?

The lag time is the delay between the maximum rainfall amount and the peak discharge. The shape of a hydrograph varies in each river basin and each individual storm event. ... This increases lag time. The peak discharge is also lower as it takes water longer to reach the river channel.

How to Calculate Basin Lag given Peak Discharge?

Basin Lag given Peak Discharge calculator uses Basin Lag = 2.78*Regional Constant (Snyder)*Area of Catchment/Peak Discharge to calculate the Basin Lag, The Basin Lag given Peak Discharge formula is defined as the elapsed time between the occurrences of the centroids of the effective rainfall and of the storm runoff hydrograph, which is an important factor in determining the time to peak of the unit. Basin Lag is denoted by t_p symbol.

How to calculate Basin Lag given Peak Discharge using this online calculator? To use this online calculator for Basin Lag given Peak Discharge, enter Regional Constant (Snyder) (C_p), Area of Catchment (A) & Peak Discharge (Q_p) and hit the calculate button. Here is how the Basin Lag given Peak Discharge calculation can be explained with given input values -> 0.00156 = 2.78*0.6*3000000/0.891.

FAQ

What is Basin Lag given Peak Discharge?

The Basin Lag given Peak Discharge formula is defined as the elapsed time between the occurrences of the centroids of the effective rainfall and of the storm runoff hydrograph, which is an important factor in determining the time to peak of the unit and is represented as t_p = 2.78*C_p*A/Q_p or Basin Lag = 2.78*Regional Constant (Snyder)*Area of Catchment/Peak Discharge. Regional Constant (Snyder) is considered an indication of the retention and storage capacity of the watershed, Area of Catchment is the geographical area from which water flows into a particular point, such as a well, stream, or reservoir & Peak Discharge is the maximum volume flow rate passing a particular location during an event.

How to calculate Basin Lag given Peak Discharge?

The Basin Lag given Peak Discharge formula is defined as the elapsed time between the occurrences of the centroids of the effective rainfall and of the storm runoff hydrograph, which is an important factor in determining the time to peak of the unit is calculated using Basin Lag = 2.78*Regional Constant (Snyder)*Area of Catchment/Peak Discharge. To calculate Basin Lag given Peak Discharge, you need Regional Constant (Snyder) (C_p), Area of Catchment (A) & Peak Discharge (Q_p).
