In the paper an evaluation of causes of an excessive moisture content of the paddock and its surface erosion have been presented. The paddock is located on the lot number 95/2 at the 12 Jodłowa Street in Kraków, that belongs to the Experimental Station of the Department of Animal Breeding and Anatomy at University of Agriculture in Krakow. In order to determine the groundwater conditions a proper filed and laboratory tests of the geotechnical parameters were carried out. Based on the current groundwater conditions of the paddock area it was stated that the rainfall does not have a proper drainage and low permeability coefficients of the soils cause its stagnation in the surface layers, which is the reason for the swamping of the ground after heavy rainfall. Based on the carried out tests and analysis a conception of drying and stabilization of the paddock area was prepared. Two types of protection were suggested – one against rainfall stagnation and another one against surface erosion, using coarse mineral soils as a drainage and cellular geosynthetic as a stabilizing protection. A collecting pipe to discharge water from the drainage was also planned.
