Form Factor using Watershed Dimensions Solution

STEP 0: Pre-Calculation Summary

Formula Used

Form Factor = Watershed Area/Watershed Length^2
F_f = A/L^2
This formula uses 3 Variables

Variables Used

Form Factor - Form Factor is a ratio of watershed area to the square of the length of the watershed.
Watershed Area - (Measured in Square Meter) - Watershed Area is an isolated area with a well demarcated boundary line, draining the rainwater to a single outlet.
Watershed Length - (Measured in Meter) - Watershed Length is distance from outlet to watershed boundary along main channel.

STEP 1: Convert Input(s) to Base Unit

Watershed Area: 20 Square Meter --> 20 Square Meter No Conversion Required
Watershed Length: 50 Meter --> 50 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_f = A/L^2 --> 20/50^2

Evaluating ... ...

F_f = 0.008

STEP 3: Convert Result to Output's Unit

0.008 --> No Conversion Required

FINAL ANSWER

0.008 <-- Form Factor

What is Form Factor?

Form factor is defined as the ratio of the basin area to the square of the basin length. The value of the form factor would always be less than 0.754 (for a perfectly circular watershed). The smaller the value of the form factor, the more elongated will be the watershed.

What determines the Shape of a Watershed?

The Shape of a Watershed influences the shape of its characteristic hydrograph. For example, a long-shaped watershed generates, for the same rainfall, a lower outlet flow, as the concentration time is higher.

How to Calculate Form Factor using Watershed Dimensions?

Form Factor using Watershed Dimensions calculator uses Form Factor = Watershed Area/Watershed Length^2 to calculate the Form Factor, The Form Factor using Watershed Dimensions formula is defined as the ratio of the basin area to the square of the basin length. Form Factor is denoted by F_f symbol.
