The Harz massif is located in the northern part of the area of Germany. The Harz rocks compose geologically hard, horst, strongly metamorphized upper-paleozoic complex with mainly developed Devon and lower-carbon formations. Plutonic formations like harzburgite-gabbro and banatite-granitoide formation to which are related the massifs Harburg, Broken, Ramberg, Oker and Bode dyke are typical for Harz.

In this paper a mathematical model is offered, which characterizes the erosion process in mountainous countries. It takes into consideration the inclination and geographical latitude of the area. The results obtained by this model appeared to be rather close to the experimental data. The observed deviations can be brought to zero taking into account anti-erosion tendency of the ground (the infiltration coefficient).
