The paper deals with the results of five year observations and measurements of contemporaneous morphologenetical processes, modelling a group of loess gullies and their basins situated on the Nałęczów Plateau in NW part of Lublin Upland. The relief has been shown on the background of general physicogeographical characteristics (fig. 1-5). The modelling of the gullies and their basins is the result of mor- phogenetic processes which are both destroying (linear erosion, superfical washing, suffosion, mass movements) and constructing (accumulation on the bottom and on the forested slopes). Quantitative measurements showed that the lowering of the slope surfaces as a result of washing out equalled to 6.8 - 11.3 mm per year, erosional thresholds of the bottom removed with velocity 1.0 - 4.5 mm per year, while creeping of the cover of the slopes was with velocity 5-10 mm per year. The bottom material has been accumulated in the shape cones, the accumulation rate being here 4.3 - 14,7 mm per year. The figures presented give mean value of some years of observation. They may be considerably larger under the extreme conditions (e.g. after storms). Differentiation of physicogeographical conditions of the basins enabled elimination of the zones characteristic by the domination of the process or groups of processes (fig. 6). There has been distinguished: -the area of loess top surface and gently slopes, denudational valleys, slopes of main gully and its branches, bottom of the main gully and its branches. Erosional risk of distroying of the basin is not uniform and this must be taken into consideration when is projecting antierosional.

Investigation of eolian soil erosion were carried out on the Lublin Upland and partially neighbouring regions in the period 1981-1985. The subject of the researches were the eolic processes occuring in the time of dryness of the soil and lack of vegetation as well as in the winter time, when wind and snow were active simultaneously (niveo-eolic processes). The investigations allowed to present the quantitative characteristics of the eolic processes, the index of which depends of the size of eolic accumulation (g/m² or t/km² ). It has been found that the extreme values varied from 8.7 to 524 t/km², while the average values from 7.5 to 224 t/km (tab. 3). The eolian soil erosion was most intensive during winter and early spring, when the snow cover was thin. Mostly eroded are soils formed on loesses as well as the dried up sandy soils. The fundamental influence exerted the way of utilisation: unfavourable are big areas uner one kind of cultivation as well as the lack of the interfield afforestation.
