The objective of this research was to estimate soil and water losses of a Red Yellow Argissol, using a pendulum rainfall simulator. Rainfall was simulated for 35 min at the intensities of 30, 40, 50, 60 and 70 mm h-1, which corresponded to kinetic energy values of 138, 184, 229, 275 and 321 J m-2, respectively. Cumulative soil and water losses were recorded with time at 5 min intervals. The results of soil and water losses were then fitted by regression equations. The fitted equations yielded soil and water losses that varied from 2.83 to 26.82 g m-2 (for soil) and from 0.00209 to 0.01370 m³ m-2 (for water) when the rainfall kinetic energy varied from 138 to 321 J m-2. Fitted and field measured soil and water losses showed a maximum variation of 3.4 and 5.7%, respectively.
