The aim of studies was the recognition of the contemporary denudation considering tillage translocation and water soil erosion. This study was performed in the typical last glacial relief. The Cs-137 inventory was analysed along two hillslope profiles and at their footslopes. The value of soil erosion and sedimentation was calculated using the proportional model and the simplified mass balance model...
The estimation of soil erosion rates in complex tropical agricultural systems is difficult and most of the traditional methods have serious limitations. The ¹³⁷Cs technique allows to obtain relatively quickly retrospective medium term soil erosion results. The spatial variation of soil erosion rates was studied, in a small catchment under intensively cultivatcd fields and permanent grasslands on the...
The paper presents the results of slopewash studies carried out in hydrological years 2007-2008 on 7 runoff plots located within the marginal part of the Carpathian Foothills near the Research Station of the Institute of Geography and Spatial Management in Łazy. All the plots were 2 m wide. Four of them were 22.1 m long while the remaining three were 11.1, 5.5 and 2.8 m in length. All the plots were...
Monitoring of water erosion and runoff processes was conducted in an agricultural micro loess catchment of 1,05 ha area located in the Lublin Upland. Results of the studies shoved that, over 250 m³ of runoff and about 11 t of soil was removed from the catchment during two and half year. On the basis of results a relationship between temporal rainfall intensity and runoff rate was developed in the...
The study aimed at evaluating the changes occurred in loess soils of Opatówka river catchment (Sandomierska Upland) due to surface water erosion and long-term agricultural performance. The survey was conducted in two micro-catchments on three cross-section transcets. Soil pits and bores were made, and soil samples to laboratory examinations were collected to determine the soil type, soil texture,...
In years 2007-2009 soil erosion measurements were conducted on plots and hillslopes with not separated area. The separated plots were closed by the Gerlach troughs with collectors. Measurements with not separated area were carried with the modified collectors of Słupik (entrance width 0,5 m). The aim of the paper is to compare the results and to evaluate the usefulness of the small collectors. Annual...
This work presents a use of the ¹³⁷Cs method in the reseach of soil erosion and sedimentation on the agricultural loessial land. There is an urgent need to obtain reliable quantitative data of the soil translocation in agricultural areas and to choose an effective method of soil conservation. After deposition on the land surface, ¹³⁷Cs is rapidly and strongly adsorbed by soil particles. The isotope...
The Meghalaya Plateau, located in NE India, forms hilly horst block elevated to about 2000 m a.s.l. In the subtropical monsoonal climate, with strong mean annual rainfall gradient from 11,000 mm in Cherrapunji to 2,200 mm in Shillong and 1,600 mm in Gauhati were developed several cultivation systems. The shifting cultivation is the oldest and predominant system at lower elevations (such near Gauhati)...
W artykule przedstawiono wyniki przeprowadzonych w latach 2000-2002 pomiarów strat gleby wskutek erozji wodnej na trzech poletkach doświadczalnych. Poletka zostały założone w Stacji Doświadczalnej Puczniew położonej w centralnej części Polski. Poletka miały jednakową szerokość (4 m) oraz różne długości: 40 m, 60 m, 80 m. Średni spadek poletek wynosił 10%, a kształt stoków był wypukły. Na powierzchni...
Pomiary uwilgotnienia gleby lessowej prowadzono na erodowanym stoku w zlewni Mielnicy na obszarze Wzgórz Trzebnickich. Okresy, w których je prowadzono charakteryzowały się jednymi z najniższych sum opadów występujących na tym obszarze. Pomiary prowadzono techniką TDR w charakterystycznych miejscach rzeźby stoku. Rozpoznanie warunków pedologicznych wykazało istnienie podeszwy płużnej a tym samym utrudnienie...
These procesess are conditioned by natural parameter of environment and its using. There were evaluate the surface runoff and erosion values on different kinds farming land on base of long-term measurements. Annual size surface fl ow and soil erosion were correlated mutually and with precipitation. The subsurface runoff is important element of water circulation. Authors showed the amount and course...
