Which factor is NOT included in the RUSLE equation?

The RUSLE equation, which stands for the Revised Universal Soil Loss Equation, is used to estimate soil erosion rates. It is based on several components represented by different variables. Each component plays a critical role in calculating the potential soil loss due to erosion.

In the context of RUSLE, the variables are defined as follows:

• R represents rainfall and runoff erosivity, which measures the impact of precipitation on soil erosion.

• K denotes soil erodibility, which reflects the susceptibility of soil particles to detachment and transport by water.

• P symbolizes the support practices that can affect erosion, such as contouring or terracing, which help to manage runoff and soil movement.

The variable that is not part of the RUSLE equation is H, which typically does not represent any erosion factors within this model. Since R, K, and P are all integral parts of the equation that directly influence soil erosion dynamics, identifying H as the absent component is essential for understanding the structure of the RUSLE model.

Clarifying the roles of R, K, and P in the equation helps to grasp why H is not relevant in this context, as they all pertain directly to factors affecting soil erosion and conservation practices. Thus, acknowledging H
