- Abstract
- Water erosion on arable land has since the beginning of the 80's been studied frequently in Sweden because it to a high extent contributes to losses of nutrients from fields. This study discusses water erosion on arable land in a study area in southern Sweden, with an emphasis upon its relations to topographical factors, soils and land use. In the study area another investigation of water erosion was made during 1986-89.
Erosion and land use data from the winter season 1986/87 were used from this earlier study, when the highest erosion intensity was measured. The study made during 1986-89 used traditional measurement methods but this study has utilised Geographical Information Systems (GIS).
From a Digital Elevation Model (DEM),...

This study discusses water erosion on arable land in a study area in southern Sweden, with an emphasis upon its relations to topographical factors, soils and land use.

Erosion and land use data from the winter season 1986/87 were used from this earlier study, when the highest erosion intensity was measured. The study made during 1986-89 used traditional measurement methods but this study has utilised Geographical Information Systems (GIS).
From a Digital Elevation Model (DEM), interpolated with the Intercon routine of the IDRISI software package different topographical variables were calculated. The relief was best in locating the affects of water erosion.
All fields (the number is 484) were divided into five classes based on the dominated soil within each field. Clayey soils were most sensitive to water erosion. The land use mapping, however, was divided into three groups where ploughed fields showed the highest frequency of water erosion.
Comparisons between the earlier investigation and this study showed that common topographical variables used in both studies were better in locating water erosion with GIS application. Soils and land use had only small differences between the two studies. (Less)
