The variability of water runoff and fluvial transport in the upper Wieprz River catchment (300.3 km2 ) in Central Roztocze region is presented, based on results of daily measurements in Guciów from the period of 1996–2016. The study period was characterised by high variability of annual precipitation totals – from 563.2 mm (2003) to 932.9 mm (2010), with the mean annual value of 735 mm. Mean annual discharge flow in the Wieprz River ranged from 0.91 m³ ·s⁻¹ (1996) to 2.27 m³ ·s⁻¹ (2010), and extreme discharge values varied from 0.5 m³ ·s⁻¹ (1996) to 13.1 m³ ·s⁻¹ (2005). The variability of annual, monthly, and extreme discharges was moderate. The specific runoff index amounted to 4.5 dm³ ·s⁻¹ · km⁻², and it varied from 3.0 dm³ ·s⁻¹ · km⁻² to 7.6 dm³ ·s⁻¹ · km⁻². The mean annual runoff of the Wieprz River in Guciów amounted to 142 mm, with the variability in the range between 95 and 239 mm in particular years. The runoff regime showed features of nival type, moderately developed. The dynamics of transport of solutions and suspensions corresponded to seasonal and annual changes in the runoff of the Wieprz River. Mean annual fluvial transport varied from 7.8 · 103 t (1996 and 2004) to 18.0 · 103 t (2010), whereas transport of solutions constituted 89–97% of the total flux. The mechanical and chemical denudation indices calculated for the catchment amounted to 2.4 and 36.1 t · km⁻² per year, respectively. In spite of the evident increasing trend in annual atmospheric precipitation totals, water runoff did not increase, contrary to forecasts, whereas fluvial transport, particularly that of suspensions, showed a tendency of a slight decrease.

The use of the information system NIT (Numerical Information about Terrain) for the evaluation of the potential soil water erosion hazard on the river Wieprz basin has been proposed. Maps of the elementary classes of erosion hazards including slope decline, soil cover, geological structure and land use were prepared. The maps were also combined to form a mozaic cartogramme. The information gathered was presented in the form of a scheme and map illustrating the spatial distribution of potential hazards of water erosion in the investigated river Wieprz basin.

The surface layer was examined of soil, plant and water contaminated with chromium in the vicinity of the tannery waste lagoon situated in the eastern Poland. The area under investigation is located in the direct neighbourhood of the Wieprz River and cultivated fields. The aim of the paper was to determine the chromium levels in the soil and the neighbouring fields, water samples from the Wieprz River as well as in six plant species. The process of migration of chromium in soil samples from the dumping ground was confirmed. The gradient was observed of chromium level in the soil in terms of the distance from the central part of tannery waste in the direction of the Wieprz River. Increased levels of chromium concentration ranging from 2.50 to 6.27 mg kg⁻¹ dry mass were found in the examined plants.

This paper shows variability of fluvial transport of the Wieprz river. The catchment of the upper Wieprz river to profile at Guciów located in Central Roztocze Region. In Wieprz during the hydrological years 1996–2006 average annual flow is 1.32 m3⋅s–1, which correspond to the outflow – 41.5 Mm3⋅a–1. Extreme values of the flows varied from 0.5 m3⋅s–1 to 13,1 m3⋅s–1. Outflow the Wieprz river has feature for the snow-rainy hydrological regime. During the study the annual average suspended load amounted 737 Mg. The annual average dissolved load amounted 10 343 Mg. The bed load estimated of the dissolved load and 1% of the suspended load. The monthly average suspended load and dissolved load were least in the November and were highest in the April. During the period of researches, the average mechanical denudation rates 2.4 Mg⋅km–2⋅a–1. Chemical denudation rates were much higher –36.1 Mg⋅km–2⋅a–1. Their differentiation are similar in other regions of Poland.
