In the study there was presented measurement of superficial flow intensity from four sections of forest slope road. One of the road section was located where the excavation cut the drain of the intraground flow. Unit intensity of runoff from periods of low and high rainfall intensity and period of snow melting are being compared. Presented measurement shows distinctly advantage of the superficial flow from road section where the excavation cut the drain of the intraground flow over the other measured sections. This disproportion accentuates with low precipi-tations and in the period of snow melting - circa 30 times predominance. Compar-ing flows intensity from snow melting period with period with low precipitation disproportion achieves values more than 400 times. Features of road sections without the exudation of water from scarp assertion do not allow to determinate (according to this researches) strong connection of the particular feature with the intensity of water superficial flow from their pavements.
