Abstract: This paper shows variability

of fl uvial 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 fl ow is 1.32 m3·s–1, which correspond

to the outflow – 41.5 M m3·a–1. Extreme

values of the fl ows 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

for less than 10% 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.
