Ocena natężenia erozji w małych zlewniach górskich w Karpatach zachodnich
AbstractA solution to the problem of the evaluation of erosion intensity in small highland drainage basins is probable only cue to the existence of methods elaborated by the scientists dealing with erosion and hydrogeologists investigating the transport of rock waste in water courses. It is also possible due to the application of assumptions concerning The experiment while choosing suitable elements of the geographical environment that affect the intensity of erosions selected in the statistical way. Basing on the author's research done in three experimental drainage basins of the West Carpathians within the years 1973-1985 into the quantitative and qualitative evaluation of erosion processes, a choice and elaboration of physiographical parameters in 60 email drainage basin were made. Next, general erosion was determined by the Reniger-Dębski method for these drainage basins. Before making a choice of suitable elements of the geographical environment, a check of homogeneity end representativeness of sequences was carried out. Three combinations of independent variables essential at the level α = 0,05 were obtained. The following formulae were created, (1) EH = 10,5522 Cv0,1037 L0,5393 ε-0,5679; R = 0,347, F e 1,506, α = 0,231 (2) ER = 0,006948 Ps 0,95798 hs 0,4793 ε -0,3579 R e 0,446, F = 2,319, α = 0,097 (,.3) ER e 0,012556 Ps 1,301878 Cv 0,20903 ε -0,2699; 5 R = 0,422, F = 2,022, α 0.134 The absolute percent evror of the obtained formulae is included in the interval from 24,82 to 20 %. On the other hand, the absolute percent evror for the suggested formulae 2 and 3 calculated on the basis of the independent data oscillates between 19,5 % and 20,06 le The application of the suggested empirical formulae creates possibility for the determination of general erosion for a given profile limiting the drainage basins of the highland stream in the West Carpathians. The results can de applied for the determination of .general erosion in small highland drainage basins for the prediction of silting up of water reservoirs in order to design the interes of surface waters in non-controlled drainage basins.
