Them ain scope of the research was to estimate rainfall and run off erosivity factor for climatic conditions of south-westem Poland. The analysis was made on the base of 1966-2000 rainfall intensity data from Wrocław Swojec gauging station localized in the Lower Silesia region. Calculated average for years 1966-2000 rainfall and run off erosivity factor R for Wrocław Swojec was equal to 63.7 M J ha-l...
Results of water erosion studies on loess soil were presented. Analysis of data front plots of different length showed that process of erosion should be considered simultaneously in the terms of soil loss and the effective distance of soil transport. Soil losses expressed per unit area were similar to the data predicted from the USLE only inside the effective distance of soil transport (ranging front...
The paper presents results of 2-years studies on the intensity of water erosion processes in the road gully in Wielkopole near Krasnystaw. Field measurements included inventory of erosion and depositional forms. During the studies, three surface washouts that led to erosion damage were registered. Totally, erosion damage in a form of rills amounted to 144 m3 , and the volume of deposited soil material...
This paper shows velocity of water erosion incidentally meet in young glacial areas occurred after intensive summer rainfall at Daleszewo - North part of Poland. Simple calculation give the amount of 305 tones of soil material, which was washed out from surface of 9 ha. It gives average rainwash on level 35 Mg·ha-1. Locally, at rilling zone, this index reached the value even above 250 Mg·ha-1. Main...
We elaborated three new methods enabling better evaluation of the process of loosening, detaching and transporting soil particles. These methods are as follows: method of the stimulated rain causing water erosion, method of the measurement of the sample microhardness where sample is exposing on the eroding action of the rain from stimulator, evaluation method based on the measurement of the output...
Technical meaning of the word “slope” assing significantly inclined area which joins two horizontal or almost horizontal surfaces lying on different heighst. In this meaning, slope replaces and acts as resistance walls. The slopes prtect embankments and excavations, reinforce drainage ditches and regular riverbeds. The slope is a construction element of earthen structures. Reinforcement may be biological...
W dniach 31 lipca-6 sierpnia 2005 w okolicy Lublina wystąpiły wysokie, intensywne opady (tab. 1). Największy z nich miał miejsce w nocy z 3/4 sierpnia - w dwu stacjach jego wysokość przekroczyła 100 mm (ryc. 1). Był to opad o zmiennym natężeniu do 1 mm/min., trwający 4-5 godzin. W obszarze ok. 400 km2, objętym izohieta 100 mm, wystąpił intensywny spływ powierzchniowy, o skutkach erozyjnych. Wielkość...
W artykule przedstawiono problemy stateczności skarp nasypów pokrytych roślinnością. Przedstawiono wymagania dotyczące odpowiedniego przygotowania podbudowy i powierzchni skarpy przed wprowadzeniem roślinności, w tym głównie dotyczące uzyskania wymaganego zagęszczenia gruntów użytych do wykonania nasypu. Dobór gatunków roślin do zabudowy biologicznej skarpy powinien być dostosowany do rodzaju wbudowanych...
