Resumo:
The phenomena of erosion and sediment production by rainfall are evaluated based on the development of general erosion equations, from bed load formulas for river sediments, through an analytical procedure based on the basic principles of hydraulics, sedimentation and erosion mechanisms. . The verification of the obtained equations is done by comparing calculated values with erosion records previously published by other authors. Equations are also obtained for critical slope and critical shear stress that enable the establishment of the conditions for which the movement of sediments begins.
