Dicken's Formula for maximum flood discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Flood Discharge = Dicken's Constant*Catchment Area^(3/4)
Q_mp = C_D*A^(3/4)
This formula uses 3 Variables

Variables Used

Maximum Flood Discharge - (Measured in Cubic Meter per Second) - Maximum Flood discharge is the maximum volume flow rate passing through a particular location during an event.
Dicken's Constant - Dicken's Constant is a constant whose value is 6 for catchments in plains and ranges between 14 to 28 for catchments in hills, depending upon the catchment characteristics.
Catchment Area - (Measured in Square Kilometer) - Catchment Area for an empirical estimation is in square kilometers to where all water flows to a single stream, river, lake or even ocean.

STEP 1: Convert Input(s) to Base Unit

Dicken's Constant: 6 --> No Conversion Required
Catchment Area: 40.5 Square Kilometer --> 40.5 Square Kilometer No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_mp = C_D*A^(3/4) --> 6*40.5^(3/4)

Evaluating ... ...

Q_mp = 96.3257763152204

STEP 3: Convert Result to Output's Unit

96.3257763152204 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

96.3257763152204 ≈ 96.32578 Cubic Meter per Second <-- Maximum Flood Discharge

What is Catchment Area & What is Maximum Food Discharge?

A catchment Area is an area from which surface runoff is carried away by a single drainage system. The area of land bounded by watersheds draining into a river, basin or reservoir.
In Hydrology, the term “peak discharge” stands for the highest concentration of runoff from the basin area. The concentrated flow of the basin greatly exaggerates and overtops the natural or artificial bank, and this might be called a flood.

Dicken's Constant for various topography.

Dicken's Constant for various topography is as follows:
North-Indian Plains 6
North-Indian Hilly Regions 11-14
Central India 14-28
Coastal Andhra and Orrisa 22-28.
