Knowledge of surface runoff characteristics allows creating better conditions for landscape management, whether rural or urban. We focused on a determination of a volume of surface water runoff and it velocity in this paper. A direct measurement was done on an experimental area with three different slopes in a laboratory. Results of direct measurements were compared with results from a model SMODERP and NRCS method used in GIS environment. The velocity of surface runoff was also calculated by a mathematical equation used in literature. The results of surface runoff volume from GIS were equal in all cases, but not the velocity. The results of SMODERP simulation and direct measurements are similar. The calculated velocity was the highest in case of first slope, and the lowest in other cases. Differences of the velocity varied in a range 1.10 - 11.06 %. The volume of surface runoff varied more, mainly the results of NRCS Curve Number method in GIS (up to 41 %). The results show that the higher slope, the higher runoff velocity and volume is.
