Snyder's Equation for Peak Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Peak Discharge - (Measured in Cubic Meter per Second) - Peak Discharge is the maximum volume flow rate passing a particular location during an event.
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.
Basin Lag - (Measured in Hour) - Basin Lag is the elapsed time between the occurrences of the centroids of the effective rainfall.

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
Basin Lag: 6 Hour --> 6 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_p = 2.78*C_p*A/t_p --> 2.78*0.6*3/6

Evaluating ... ...

Q_p = 0.834

STEP 3: Convert Result to Output's Unit

0.834 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.834 Cubic Meter per Second <-- Peak Discharge

What is Peak Flood Discharge?

In hydrology, the term peak discharge stands for the highest concentration of runoff from the basin area. The concentrated flow of the basin greatly exaggerated and overtops the natural or artificial bank, and this might be called flood.

Which factors influence the amount of effective rainfall?

The fraction of effective rainfall increases with increased water-holding capacity in the soil. The amount of water held and retained by a soil depends upon its depth, texture, structure, and organic matter content, the finer the texture, the greater the storage capacity.
