Slope gradient is a key factor in influencing the relative stability of a slope. It determines the degree to which gravity acts upon a soil mass. Slopes are often irregular and complex, with gradients varying greatly throughout a given shoreline profile. Each slope profile section should be treated as a separate management and restoration site unit. Slope gradient can be expressed in several ways. The table and slope determination formulas below illustrate three commonly used notations.
