The paper contains analysis of the anti-erosion system in the road gully in Wielkopole, Lublin Upland. The solution implemented in the gully’s bottom is effective against line erosion – there is no gully deepening. Lack of protection of slopes results in an intense earthmass movements. At the brim zone of the gully suffosion processes occur leading to the gully widening. The eroded material is accumulated on the road and colmatage drainage system of voivodship road no. 842, what is dangerous to traffic and generates expenses. That is why anti-erosion systems should be implemented comprehensively, protecting both the slopes and the bottom of gullies. Projects of such systems should be consulted with specialist.

W pracy przedstawiono wyniki badań natężenia erozji wodnej w wąwozie drogowym w Gorzkowie na Wyżynie Lubelskiej. Program badań opierał się na badaniach terenowych, którymi objęto badania natężenia erozji wodnej, uwzględniając rodzaje i rozmiary szkód erozyjnych. W okresie badań wystąpiły trzy spływy powierzchniowe wód, podczas których powstały szkody erozyjne. Szkody erozyjne w postaci żłobin w dnie wąwozu wyniosły 64,2 m3, a objętość osadzonego materiału ziemnego na dnie wąwozu i w rowie przydrożnym wyniosła 70 m3.

The paper presents the results studies on the intensity of water erosion processes in the road gully in Gorzków on the Lublin Upland. The study program was based mainly on field determinations including the intensity of water erosion processes, taking into account the types and size of erosion damage. During the studies, three surface washouts that led to erosion damage were registered. Erosion damage in a form of rills on the bottom of gully, during the studies, amount- ed to 64.2 m3, and the volume of precipitated soil material on the bottom of gully and the roadside ditch was 70 m3.

The article presents the development of a small, midfield form of road, which cuts the side of a loessic valley. The contemporary shape of the surface was determined by GPS measurements (Leica System 500), set together in ArcView and ArcGIS. Changing of its position was determined by a field analysis of the construction of 50 profiles of the Luvisols with varying degrees of erosion or aggradation. Calculation and visualization were performed in the ‘Surfer’ program. The results are interpreted in the context of changes in the agrarian structure since the end of the 19th century. It was found that the development of erosional forms is associated with an intensive use, since the late 1930s, of the road traced at the end of 19th century. Significant rate of its cutting is also the result of earlier soil erosion, due to its agricultural use since the late Middle Ages. Until achieving the depth of about 1 m, the form was the shape of a trough, because the road also served as a zone of turning round during the cultivation of the adjacent transversal-slope fields. In the 1970s, after a change in cultivation mode, erosion took the form of a box-like section. The average annual rate of cutting into the deepest section increased from 2.5 to4 cm and the depth - to 1.8 m. These conclusions confirm the profile of deposits on the extended cone at the gully mouth at the valley bottom. Their lower series, with thickness of 1.7 m and a massive structure, are products of soil erosion accumulated for several hundred years. The laminated top series with thickness of 0.8 m is distinguished by CaCO3 content growing towards the surface. Its accumulation at a rate of 1.2 cm per year is the result of a deeper cutting of the road on the slope.
