Being a hydrologically driven process.
• Given the scope of the process, the topographic modeling in
the erosion analyses can differ in terms of complexity,
processes considered and data required for model use and
calibration, which can be empirical, physical and conceptual.
• The empirical models most used, such as USLE (Universal
Soil Loss Equation) and the revised version of USLE
(Revised Universal Soil Loss Equation - RUSLE)
• RUSLE 3D and USPED (Unit Stream Power Erosion and
Deposition) are derived from USLE to represent their
advancements by adding a physical basis that tries to relate
the morphology of the relief and the erosion defining
parameters.
