What is slope ?

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line.

How to Calculate Self Cleaning Invert Slope?

Self Cleaning Invert Slope calculator uses Self Cleaning Invert Slope = (Dimensional constant/Hydraulic mean depth)*(Specific gravity of sediment-1)*Diameter of the grain to calculate the Self Cleaning Invert Slope, The Self Cleaning Invert Slope defined as the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Self Cleaning Invert Slope is denoted by s symbol.

How to calculate Self Cleaning Invert Slope using this online calculator?
