Opis:: The studied sandstones from the Giełczew Elevation and the Chełm Hills become an important unit that ended the Neogene deposition in the Lublin Region. They outcrop in the upper partof Sarmatian sandstones building the butte elevations up 100 m high. These sandstones are porous, with an undefined oligomictic rock skeleton. They are mainly structureless but some sedimentary structures (e.g. cross-bedding, convolute stratification), are also observed. Grain skeleton consistsin general of poorly rounded quartz grains and several percent of feldspars. Quartz is represented by triangle-shaped and poorly rounded crystals, with visible mineral corrosion, which indicates ashort transport and rounded grains (extraclasts with wavy light dimming), as well as by scarcely redeposited well-rounded quartzite clasts. This skeleton was cemented with a basal-contact matrix some rock voids, microfossils and ooids, replacing the primary carbonate bioclasts. Microsedimentary and paleontological analyses documented that the studied deposits originated probably in the shallow basins (e.g. ooids presented in some samples) with varied salinity and a significant input ofriverine material.

Opis:: On the 31st July – 6th August 2005 in Lublin surroundings, high and intensive rainfalls appeared (Table 1). The highest one took place at night of 3rd–4th August and its level exceeded 100 mm in two stations (Fig. 1). It was the rain of changeable intensity to 1 mm·min–1, lasting 4–5 hours. In the area of 400 square kilometers enclosed with 100 mm isohyet, an intensive runoff with erosional effects appeared. Its size in rural area was conditioned by land use, crop structure, fi eld pattern and road network. Majority of corn fi elds determined the predominance of dispersed runoff and little rainwash. Concentration of runoff and linear erosion took place only on small area of: roads, fi elds with root plants and fi elds of aerated soil (Fig. 3). The maximum of erosion rate in the fi eld scale reached: 200 t·ha–1 of translocated material and 70 t·ha–1 of carried material, fi eld surface lowering by 5 mm and convex parts of slope by 8 cm. Deposition of material, in form of fans and proluvial covers took place in dry valley fl oors. Concentrated runoff formed here episodic channels: transport and deposition in channels being fl at and erosional channels in crops with uncovered soil. Below roads crossing the channels, potholes with the capacity to 50 m3 and bars of eroded material were formed. Most of moved soil material was left within dry valleys whereas water runoff was the main source of fl ood waters in river valleys. Specifi c outfl ow from dry valley catch ments, with the area of 5 square km, reached 1–2.5 m3·(s·km2)–1. In valleys of small perennial fl ows with catchment area less than 50 square km (for instance: Skrzyniczanka, upper Stawek and Sierotka Streams), located in zone of the highest rainfall, local fl oods appeared. They caused losses in road and hydrotechnical infrastructure. Waves from these catchments, with specifi c outfl ow to 0.8 m3·(s·km2)–1, caused relatively smaller fl ood waters in higher valleys in next days (Fig. 2). Five-times growth of fl ow in Biskupice on the Giełczew River and seven-times one in Sobianowice on the Bystrzyca river occurred. On 4th–11th August period, about 12 mm of water fl owed from these catchments but in the Czerniejówka catchment, level of groundwater raised about 30–70 cm.
