How to Calculate Friction Slope?
Friction Slope calculator uses Friction Slope = Instantaneous Discharge^2/Conveyance Function^2 to calculate the Friction Slope, The Friction Slope formula is defined as the rate at which energy is lost along a given length of channel is called the friction slope. Friction Slope is denoted by Sf symbol.
