This work is a part of erosion research, which deals with study of erosion processes on forest roads roadways with gravel cover. This paper evaluates results received from terrain measures of ambulant raining deluometric method. Measures were performed in Kremicke vrchy mountains, in the location Kovacova. Within the net of experimental sections on forest road Beriakova - Mistrikovo 10 elementary runoff microareas (0,5 x 2,0 m) were created. Artifical rainfall with the intensity of 3.84 mm per minute during 20 minutes was simulated on these microareas. Characteristics of surface runoff were detected exactly and from the volume and cloudness of surface runoff absolute soil erosion loss was evaluated. High values of surface runoff (90-95 % of simulated rainfall) were determined. Absolute soil erosion losses reached values 55,34-357,23 g per sq m dependent on the amount of available material for potential erosion.
