This report presents the influence of the erosion process below the Jeziorsko reservoir on changes in Warta river bed. It contains changes of grain-size in years and sections below the Jeziorsko dam, changes of bottom level in the Warta river reached between the sill No 2 and staff-gauge Uniejów in the years 1989-2001, water level in the Warta river reached between the sill No 2 and staff-gauge Uniejów...
The paper presents results of investigations conducted on models of the dam in two scale with basin and horizontal bed protection. Range of investigations contained measurements of temporal velocity at a points on length of the channel below the bed protection. The measurements were conducted for two cases. The first consisted for measurements on flat and stable bed of channel and second for developing...
The main scope of the research was to estimate rainfall and runoff erosivity factor for climatic conditions of Puczniew located in central Poland. Analyzed period covers years 1980-2002. Criteria accepted for erosivity was meet for 211 rain events. Index R varied from 12,6 in 1989 to 195,6 in 2001. Largest values of indexes R and Rr has been noted for June, July and August. January and February were...
Valuable cultural landscapes have developed on mountainsides as a result of existing cultivation. Their survival was ensured by a traditional way of soil use. Due to a current lack of the traditional use of the mountainsides, their valuable cultural landscapes are threatened, they are even to face a complete extinction. Moreover, in some cases the lack of the traditional use of mountainsides also...
W artykule opisano badania, których celem było rozpoznanie procesów deformacji sekcji przelewowych progów siatkowo-kamiennych oraz zjawisk erozyjno-akumulacyjnych w dolnym stanowisku. Badania przeprowadzono na progach gabionowych Kamionka i Łętów położonych na rzece Wildze. Na zmiany profilu dna w wyniku akumulacji rumowiska duży wpływ miała realizacja progu położonego powyżej w miejscowości Oziemkówka...
An irrevocable effect of the process of tillage erosion is truncation of the surface horizon and the translocation and accumulation of the eroded soil material at the foot of the slope. It concerns mostly fine soil fractions, humus and nutrients (C, N, P). The rate of that process depends on the original morphology of soil profiles and the susceptibility to erosion, the amount and intensity of precipitation,...
